Summary of Enterprise Environmental Protection Work 1 I. Company Profile
Founded on September 28th, 20**, the company is a private enterprise specializing in aluminum smelting, with 750 employees. The company's 230KA large-scale prebaked aluminum electrolysis project is one of the key construction projects in the province. The design work is undertaken by xx Branch of xx Al-Mg Design and Research Institute. The designed annual aluminum ingot production capacity is 6.5438+400,000 tons. After putting into production, the annual sales revenue is 2 billion yuan, and the profit and tax are 250 million yuan. The total investment of this project is 850 million yuan, which will be built in two phases. The existing scale is 70,000 tons in the first phase, which will be held on February 28th and July 8th, 2007. *** 108 batteries, with a total investment of 450 million yuan, and the annual electricity consumption reaches1000 million kwh. By the end of 20**, * * had produced 93,757.637 tons of aluminum ingots, and in the first quarter of this year, * * had produced aluminum ingots 15876.362 tons.
Second, the process characteristics
SY230 prebaked anode electrolyzer of our company integrates all kinds of advanced technologies and achievements at home and abroad, and adopts fully enclosed automatic material conveying system, energy-saving automatic monitoring flue gas purification and recovery system, intelligent fuzzy control system, auxiliary management of the whole process of aluminum electrolysis production, stable power supply system with high degree of electrical automation, advanced spectral analysis quality monitoring facilities, etc. The process is compact and highly automated, and it is in the advanced ranks in the same industry in China. The whole production process belongs to the clean production process of aluminum electrolysis industry.
Third, about environmental protection governance.
For electrolytic aluminum industry, environmental protection is a very important basic condition. Since 2000, the state has introduced many measures to implement environmental protection policies and closed many enterprises that do not meet environmental protection standards. Therefore, it is self-evident that xx Aluminum, established in this environment, attaches importance to environmental protection. Company leaders conscientiously implement the relevant national industry policies and systems, and look at the problem from a long-term perspective, regardless of the construction period or the current production period.
1, high standard design, laying a technical foundation.
The impact of electrolytic aluminum production on the environment is mainly air, fluoride is the main characteristic pollutant discharged, and the other is dust. In order to meet the standard, our company first proposed to the design unit that it must be put into production according to the national policy. After re-screening, we selected a powerful national design unit-xx Branch of XX Aluminum-Magnesium Design and Research Institute, and organized a group to inspect the selection of more than 20 large and medium-sized aluminum plants in China, and finally selected SY230 series storage tanks.
2, highlight the governance, pay attention to technical standards.
Since the company put into production, it has always attached great importance to environmental protection standards. In strict accordance with the Environmental Air Quality Standard (GB3095- 1996), Urban Regional Environmental Noise Standard (GB3096-93), Noise Standard at the Boundary of Industrial Enterprises (GB 12348-90) and Surface Water Environmental Quality Standard (GB 3838-90)
First of all, increase investment to ensure that environmental protection hardware meets the standards. The total investment of 70,000 tons in the first phase of the company is 450 million yuan, and the total investment in environmental protection is about 50 million yuan. Equipped with two sets of purification and recovery systems, the fully enclosed feeding system is adopted, and the flue gas in the electrolytic cell is treated centrally and discharged up to standard by using the principle of bag dust collector and Venturi dry recovery and purification.
Secondly, classified comprehensive management. The pollution of electrolytic aluminum is nothing more than gas, dust, fluorine and slag. In view of the above pollution sources, the company uses technical treatment (using the strong adsorption capacity of AL2O3 to recover fluorine dry adsorption into favorable fluorine-containing raw materials for production, and the recovered dust AL2O3 and ALF3 are returned to the electrolytic raw material silo, and the remaining carbon slag and other materials are classified and piled up, and are regularly purchased or returned to the carbon factory as production raw materials or fuel. Effective substances are retained and utilized, harmless gases are discharged up to standard, and solid materials are reused or used as raw materials in other industries, which not only controls but also comprehensively utilizes, turning waste into treasure, creating benefits for enterprises and reducing losses;
Third, ensure that 100% of environmental protection facilities operate. Because I realized the importance of environmental protection, I also tasted that comprehensive management is the sweetness of turning waste into treasure. All the company's environmental protection treatment equipment ensures the 24-hour operation of 100%, laying a scientific foundation for creating a beautiful and clean environment. At the same time, the company has set up a purification and recycling workshop and an environmental protection department to manage, supervise and implement the company's environmental protection atmosphere and run well for a long time. In addition, the company also actively invited the county and city environmental protection departments to guide and strengthen monitoring, timely rectification and improvement, and finally reached the industry standard.
3. Greening the enterprise environment and optimizing management indicators.
In order to further strengthen employees' environmental awareness, the company organized employees to carry out voluntary greening activities. The company spent more than 500,000 yuan to afforest more than 90% of the open space in the first phase of the factory as planned, and divided the responsibility areas. Entering the company's gate gives people a real feeling of garden-style factory, and the enterprise is thriving, and all indicators have reached the advanced level of the industry:
① The quality 100% of HJ brand aluminum ingots for remelting conforms to national standards, and has been declared as provincial famous brand products;
(2) The AC power consumption of electrolytic primary aluminum is below 14000kwh/t-AL, reaching the domestic advanced level;
③ Fluoride emission concentration 1.9mg/nm3 (national standard < 3 mg/nm3 =), dust emission concentration 8mg/nm3 (national standard ≤30mg/nm3), and dust removal efficiency as high as 99%, reaching the leading level in the same industry;
(4), the implementation of fully enclosed circulating water, basically no industrial water discharge;
(5), the enterprise and the surrounding truly achieved mutual supervision, * * * with management, * * * with environmental advantages.
Fourth, make unremitting efforts to create tomorrow's environmental protection enterprises.
With the development of enterprises and the progress of society, reaching environmental protection standards is a kind of knowledge and requirement. Our company has also planned the future environmental protection development plan. We will sum up past achievements, learn from foreign successful experiences, constantly improve the environmental protection image of enterprises, actively respond to national policies, cooperate with environmental protection departments at all levels to intensify efforts, seek truth from facts, do a good job in environmental protection governance of enterprises, and make unremitting efforts to create tomorrow's environmental protection enterprises.
Summary of enterprise environmental protection work 2 We always adhere to the safety production policy of "safety first, prevention first, comprehensive management", take the "three actions", "investigation and management of hidden dangers" and the implementation of "year of safety production" as an opportunity, while strengthening the basic management of on-site safety, pay close attention to the construction of safety team, vigorously shape the enterprise safety culture, comprehensively improve the safety practice ability of managers, comprehensively improve the safety awareness of all employees and continuously consolidate safety.
When the overhaul and four technical transformation projects were put into production in xx, the number of industrial accidents was the same as that in xx, and all kinds of illegal behaviors were the same as that in XX. The completion rate of safety education and training plan was 100%. The completion rate and rectification rate of the hidden danger investigation scheme are 100% and 99% respectively (some of them have not expired or need to stop production for maintenance), and the death toll of production safety accidents is zero. There were no major production safety accidents, major environmental pollution accidents, major occupational accidents, major fires and personal injury accidents throughout the year, and the discharge of "three wastes" reached the national standards. This achievement benefits from the great attention of leaders and managers at all levels of the company and the strict management and picketing of the picket brigade. In order to further summarize the achievements, accumulate experience and improve the management level of production safety, the work of production safety in xx is summarized as follows:
First, improve various rules and regulations and implement institutionalized management.
Give priority to improving various rules and regulations. This year, our department has enriched and supplemented the following rules and regulations: safety production responsibility system, safety production acceptance regulations, environmental sanitation department responsibility system, contractor responsibility system and related regulations. And the system is improved and transformed into management implementation. For example, after the introduction of the contractor responsibility system, unqualified managers will be assessed according to their quality and working ability.
As another aspect of sanitation work, it is the problem of charging. After we established the post responsibility system for toll collectors, the duties of toll collectors are clear, the tasks are clear, the rewards and punishments are clear, and the work is more proactive than before, so that this year's charging work can be better completed under the situation of fee reform.
In personnel management, secretarial staff are engaged in the collection and arrangement of personnel files in management units, and the workload is very huge. In recent years, family planning work must also be strictly controlled. In the case of less manpower and heavy workload, they can still complete the task perfectly, manage the archives work and family planning work in an orderly way, and take time out to build a computer charging platform for the charging work.
Two, improve the contract responsibility system, promote the implementation of quality service and safety in production.
Due to the continuous expansion of production in previous years, the proportion of new workers is large, which leads to the reduction of labor production efficiency. Therefore, in order to achieve a high standard of production quality and service quality, I tried to reduce the workload to varying degrees in terms of cleaning and fleet, focusing on training workers' production skills. Since the beginning of this year, according to the production capacity of personnel, our bureau has further improved the contract responsibility system, so that every employee can freely combine according to the regulations, handled some bad employees, ensured quality service, and made unremitting efforts in safety production, which improved production efficiency and reduced production costs.
Third, the reform of fees has achieved initial results, and management is moving towards standardization.
For the problem of difficult charging, our department has been exploring solutions for several years, and has repeatedly proposed that water, electricity and sanitation fees should be charged in one window, but it has not been implemented for various reasons. Although the above scheme has been implemented in neighboring counties and cities and some towns and villages in our city, our bureau is still a backward manual charging method. In order to solve this backward charging method and keep up with the pace of building an information-based city in our city, the leading group of our department has made up its mind to implement the scheme of paying garbage fees by banks from this year 10. Through careful division of labor, since July, all the staff of our department have started their own actions according to the division of labor: contacting the computer software company to make a set of charging system software according to the specific charging situation of our department; At the same time, arrange for the collection and transportation staff to come to the door to sign a service contract with the residents and a power of attorney to pay the garbage collection and transportation and sanitation cleaning fees; For other customers, start with the store and sign a power of attorney with it. Then re-enter the signed data of * * households and * * units into the computer program. After several months of fighting, the first bank deduction was officially implemented on 10/3. The result of deduction is gratifying, and the household deduction is successful, reaching more than 60%; Units (mainly shops) successfully deducted * * households, which also reached 50%.
The first attempt of the bank to pay the garbage fee laid the foundation for our office to gradually realize the standardization of management and the automation and scientificity of the office system. This charging software creates a computer charging platform that can be operated and queried on multiple computers at the same time, which changes the backward manual door-to-door charging method, ensures the safety of charging work, and paves the way for the future development of the city and the expansion of data storage.
Fourth, there is a problem.
While the reform work is going smoothly, I also face certain problems, especially the problems of difficult charging and garbage disposal. Because this reform of paying garbage fees by banks is the first attempt, of course, there are many problems, such as the error between the account name entered into the computer and the name on the passbook of bank customers; Some families failed to deposit enough money into the bank passbook on time; Some households have wrong accounts and so on. This led to the unsuccessful deduction. Faced with this series of problems, the staff in our office did not flinch. After the staff of the office carefully investigated the problem and the collectors patiently explained it to the residents, the problem was gradually solved. However, quite a few of the more than 10,000 households in our office are unwilling to sign service contracts and authorization letters to pay for garbage collection, transportation and sanitation. Some shops are reluctant to sign because of their own stability and long-term nature. This has caused certain obstacles to the standardization of our bureau's charging work. In addition, for the tenants of rental houses, we can only collect cash. These problems need to be further solved.
On the other hand, after several years of continuous efforts, the urban area of our city has found a way of garbage collection and treatment through continuous exploration, but it needs to be continuously improved. The garbage collection and disposal in our office is gradually moving towards standardized management. And I'm in a temporary landfill built by Heshuntang, which is nearly full due to a large number of dumping. This is undoubtedly another serious problem for our garbage outlet. Judging from the current garbage disposal capacity, if we can't find a suitable place as a garbage disposal site by next year, it will greatly affect the solution of the garbage removal problem in our place. This is a major problem that needs to be solved urgently.
With the correct guidance of leaders at all levels and the unremitting efforts of the vast number of sanitation workers, the sanitation work in our city has indeed achieved gratifying results. But looking forward to the future, with the continuous development of the South China Sea economy and the further acceleration of urban construction, urban environmental sanitation is more important and the task we face is more arduous. All the staff of our office will continue to work together in Qi Xin, cheer up the spirit, foster strengths and avoid weaknesses, and make due contributions to the construction of Nanhai city; At the same time, overcome difficulties, deepen reform, and constantly create a new situation in sanitation.
Summary of enterprise environmental protection work 3 According to the spirit of provincial and municipal environmental protection conferences and the special work conference on environmental pollution remediation of petroleum development enterprises in northern Shaanxi, in order to further improve the environmental quality of our county's oil areas and promote the healthy and orderly development of oil exploration enterprises, our county adheres to the working idea of taking publicity and education as the guide, focusing on the construction of clean and civilized well sites in oil areas, strengthens the construction of environmental protection infrastructure and ecological environment, strengthens law enforcement supervision and inspection, strictly controls environmental protection approval, and comprehensively carries out environmental pollution remediation in oil areas, and the environmental quality of oil areas has been significantly improved. The special rectification of environmental pollution in our county oil region is reported as follows:
First, strengthen leadership, consolidate responsibilities, and ensure the effectiveness of special rectification work.
In order to ensure that the special rectification work of environmental pollution in oil development enterprises in northern Shaanxi has achieved remarkable results, we immediately held a special meeting according to the Implementation Plan of Special Remediation Action for Environmental Pollution in Oil Development Enterprises of the Municipal Environmental Protection Bureau, and made specific arrangements and arrangements in combination with the actual situation of our county, and formulated the Implementation Plan of Special Remediation Work for Environmental Pollution in Oil Areas of the County, with Director Zhao Wenjiang as the team leader, Deputy Director Wang Yajun and the captain of the Environmental Monitoring Brigade as the deputy team leaders, instructor Ma and the captains of the law enforcement squadron Guo and Bai Shichang.
Second, strengthen the publicity of environmental protection laws and regulations and enhance the environmental awareness of the whole people.
Focusing on the special rectification actions of environmental pollution of petroleum development enterprises, we went deep into the oil region, distributed more than 30,000 copies of publicity materials related to laws and regulations such as the Environmental Protection Law and the Regulations on Environmental Protection of Coal Oil and Gas Development in Shaanxi Province, and required each well site to brush and write more than 2 permanent environmental protection publicity slogans and more than 3,600 permanent slogans. And using cable TV stations in cities and counties to report environmental news regularly, a feature film on special environmental remediation work in oil areas was produced; Insist on compiling and distributing a special rectification work briefing every week, and timely notify the enterprises that don't know enough about the special action of oil pollution control and pay low attention to it, so that the environmental awareness and legal concept of enterprise legal persons are generally enhanced, and a good public opinion atmosphere is created for comprehensively carrying out environmental pollution control in oil areas.
Third, strengthen the comprehensive improvement of the petroleum environment and comprehensively improve the environmental quality of the oil region.
1, strictly control pollution sources. For newly laid oil wells, strictly implement the environmental impact assessment method and the system of environmental protection first approval, and completely put an end to laying oil wells along rivers, roadsides, fields and water source protection areas; For newly exploited oil wells, the "three simultaneities" system should be strictly implemented, and any environmental protection facilities that fail to meet the requirements are not allowed to be drilled and put into production; Oil development enterprises that do not implement the "three simultaneities" system and do not meet the requirements of clean and civilized well site construction standards will no longer approve new oil wells. A total of 7 illegal acts of unapproved construction and construction while approving were investigated and dealt with, and 7 cases were shut down. Up to now, the environmental impact assessment rate of oil development enterprises and the implementation rate of the "three simultaneities" system have reached 100%.
2. Comprehensively carry out the construction of clean and civilized well sites in oil areas. This year, leaders, squadrons and cadres are still adopted to comprehensively promote the construction of clean and civilized well sites. At present, our county * * has a total of well sites 1970 and 4,299 oil wells, and has built clean and civilized well sites 1868 and 4,052 oil wells with a completion rate of 94%. Among them, the "trilateral" well sites are all clean and civilized. (The First Oil Production Plant of Changqing Oilfield has 5 17 well sites, 0/073 oil production wells and 48/kloc-0 clean and civilized well sites, with a completion rate of 93%; There are 99 well sites and 235 oil wells in the Fourth Oil Production Plant of Changqing Oilfield, and 86 clean and civilized well sites have been built, with a completion rate of 87%. Pingbei Management Department of Changqing Oilfield has 1 12 well pads and 5 12 oil production wells. Clean and civilized well sites were built 102, with a completion rate of 91%; There are 7 well pads and 24 oil wells in Lianxi II Project Team of No.5 Oil Production Plant of Changqing Oilfield, and 7 clean and civilized well pads have been built, with a completion rate of 100%.

3. Strengthen the construction of sewage treatment facilities. The annual sewage output of oil development enterprises in the county is 6.5438+0.456 million tons, the sewage reinjection amount is 654.38+0.10.36 million tons, and the reinjection rate is 78% (including: the annual sewage output of Changqing Oilfield development enterprises is 856,000 tons, and the reinjection rate is 854.38+0.000%; The annual output of sewage in Xingzichuan Oil Production Plant of Yanchang Oilfield Co., Ltd. is 600,000 tons, and the reinjection rate is 47%. There are 6 sewage reinjection stations 16 and 270 sewage reinjection wells in the county. Xingzichuan Oil Production Plant plans to invest 250 million yuan to build six joint stations, one of which has been completed and the others are under construction.
4. Strengthen the supervision of oil pipelines. The oil pipeline in our county is 254.5 1 km, of which: the oil pipeline of Changqing Oilfield Development Enterprise is 2 19.55438+0 km; The oil pipeline of Xingzichuan Oil Production Plant is 35km, with an annual investment of more than 6 million yuan in 20xx. The oil pipeline from Bath to Dongying13km has been built, and all the debugging has been completed. We have sent more than 200 people (times) to inspect more than 300 kilometers of oil pipelines.
5. Strengthen environmental greening and hardening construction in oil areas. In April, the county environmental protection bureau formulated and issued the implementation plan of oil area greening, organized manpower to strengthen supervision and inspection, and urged all oil exploration enterprises to use 1 month to comprehensively afforest the inside and outside of the well site, slope protection and both sides of the road. Up to now, petroleum exploration enterprises have invested a total of 43 million yuan, with green area of 10 17 mu and hardened roads of 509 kilometers.
6, is the full implementation of mud waste liquid brick making technology. In order to achieve the goal of harmless treatment rate 100% of drilling mud waste liquid in our county. This paper introduces the brick-making technology of drilling mud waste liquid, which was piloted in Jianghan Oilfield, held on-site meeting and fully promoted, and the target task of harmless drilling mud waste liquid reached 100%.
7. Strengthen law enforcement inspection in oil regions. We have adopted the measures of "one law, two stops and three rectifications", further strengthened law enforcement, and severely punished acts such as littering, dumping sewage and throwing sewage pools. And other illegal acts, focusing on the supervision and management of the recovery and utilization of onshore crude oil in oil areas, so that the utilization rate of onshore crude oil reaches 54%. This year, more than 2,800 people were dispatched, 3,000 wells were inspected, illegal acts were investigated and dealt with 13, and a fine of 4 10000 yuan was imposed. Especially in the pollution accident in Wangjiawan work area of Xingzichuan, 68 oil wells were shut down and rectified within a time limit.
In a word, in the special rectification activities of environmental pollution of oil development enterprises carried out by provinces and cities, our county has made clear its responsibilities and paid close attention to implementation, further strengthened the supervision and inspection of law enforcement, strengthened the comprehensive management of the oil region environment, effectively solved the outstanding problems existing in practice and obviously improved the environmental quality of our county oil region. In the future, we will continue to strengthen the construction of environmental protection infrastructure and ecological environment, increase investment in environmental pollution control, strengthen law enforcement supervision and inspection, strictly control the first batch of environmental protection, and ensure that the environmental improvement work in our county oil region will reach a new level.
