since last year, Guiyang has launched the largest and most extensive air pollution control work in history, set up a leading group for tackling key problems in improving ambient air quality in Guiyang, and launched seven special control works jointly carried out by 28 member units, including dust control on construction sites, vehicle exhaust pollution control, industrial waste gas control, cooking fume control, oil and gas recovery control, non-coal mine control and environmental greening improvement.
according to the analysis, dust pollution has become one of the main reasons that affect the ambient air quality in Guiyang, because with the rapid development of urbanization and industrialization in Guiyang, several construction sites have started at the same time, and dust pollution sources are widely distributed and belong to unorganized emission sources, and some construction sites do not follow the rules.
it is the key to curb dust pollution and block the source. Since 2113, the departments of housing, construction, urban management and traffic control have jointly enforced the law on the present situation of dust pollution in construction sites and roads in Guiyang, intensified the inspection of construction sites, and strengthened the daily supervision of engineering transport vehicles and muck trucks.
according to statistics, last year, the municipal and district housing and construction bureaus inspected 1276 projects under construction and issued 1156 rectification notices. For 24 construction sites with many problems in inspection and supervision, 33 construction units and 19 supervision units involved were given to informed criticism in batches, and the construction units and supervision units were suspended from participating in project bidding activities and undertaking new construction projects until the rectification and review reached the requirements, and the bad behaviors of the construction units and supervision units were recorded and included in the credit files.
At the same time, Guiyang Public Security Traffic Management Bureau investigated and dealt with all kinds of traffic violations of engineering transport vehicles (including muck trucks) that affect air quality, especially those that are prone to dust, and * * * investigated and dealt with 3,245 traffic violations of engineering transport vehicles; The Municipal Urban Management Bureau dispatched more than 9,861 vehicles and more than 58,111 sanitation workers to manually clean sanitation facilities (garbage bins, trash cans, garbage collection boxes, etc.) every day, with an average daily manual cleaning of 17.23 million square meters and a mechanical washing area of 9.4 million square meters; In 2113, the city's environmental inspection agency * * inspected 311,689 motor vehicles, with a regular environmental inspection rate of 95.63%. The city * * * issued (including renewal) 291,111 sets of environmental protection signs for motor vehicles, which laid the foundation for Guiyang to carry out vehicle classification management.
in March this year, Guiyang city started a new round of joint inspection of ambient air quality, and intensified the remediation of dust pollution on construction sites. Through unannounced visits and joint check-up at night, it focused on the inspection of night construction sites, road dust and muck transportation, dust pollution in non-coal mines and other issues.
During this period, Guiyang Housing and Urban-Rural Development Bureau strictly carried out grid management on 665 construction sites, and put the supervision responsibility of civilized construction on each supervisor, and supervised the cleaning and leakage prevention of vehicles on the site, the coverage of muck and materials, the implementation of dust reduction measures, and the hardening and cleaning of entrances and exits.
At the same time, Guiyang Housing and Urban-Rural Development Bureau, together with the Municipal Urban Management Bureau and the Municipal Public Security Traffic Management Bureau, jointly set up checkpoints at night, and set up checkpoints at key sections of Guiyang every night to check the passing muck trucks, commercial concrete trucks and gravel transport vehicles.
Multi-pronged approach-
Preliminary results
In addition to dust control, Guiyang has also played a "combination boxing" to prevent and control air pollution from six aspects, and achieved phased results.
Vehicle exhaust pollution has become an important air pollution source. In order to reduce the negative impact on air quality caused by excessive vehicle exhaust, Guiyang Motor Vehicle Pollution Prevention and Control Management Center has carried out regular environmental inspection of motor vehicles, standardized motor vehicle repair business and random inspection of roads polluted by motor vehicles and exhaust gas. In 2113, the city's environmental inspection agency * * inspected 311,689 motor vehicles, with a regular environmental inspection rate of 95.63%, and sampled 275 motor vehicles throughout the year, effectively preventing vehicles with unqualified exhaust gas from driving on the road.
gradually promote the treatment of industrial waste gas. In recent years, in order to save energy, reduce consumption and reduce pollution, Guiyang City has adjusted the industrial layout of the whole city, completed the relocation of Guiyang Cigarette Factory and Guizhou Cement Factory, and promoted the relocation of Guizhou Tire Co., Ltd. and Shougang Guiyang Special Steel Factory. Gradually complete a number of enterprise waste gas treatment projects, such as sulfuric acid production from flue gas desulfurization of coal-fired boilers in Guizhou Branch of Chinalco, power generation from yellow phosphorus tail gas in Guizhou Qianneng Tianhe Phosphorus Industry Company, and sodium formate production from yellow phosphorus tail gas in Qinglitianmeng Chemical Company. Formulate the Comprehensive Improvement Plan for the Prevention and Control of Industrial Air Pollution in Guiyang City, take 67 industrial enterprises as key prevention and control enterprises, specify the special person responsible for prevention and control, and conduct a comprehensive inspection on the operation of environmental protection facilities, smoke and dust pollution, and exhaust gas discharge up to standard. Relocation and transformation of enterprises with high energy consumption and high pollution in the central city will be carried out. Among them, Guiyang Weichunyuan Food Co., Ltd., Guiyang Kangle Bean Industry Co., Ltd. and Guiyang Sanlian Dairy Co., Ltd. plan to move out of the central city this year, and Guizhou Laogandie Food Co., Ltd. has included coal-fired boilers into gas-fired boilers in its work plan. The denitration project of five cement production lines in Guiyang Conch Panjiang Cement Co., Ltd., Guizhou Jinjiu Cement Co., Ltd., Guiyang Orchid Cement Co., Ltd., Guizhou Miao Ling Building Materials Co., Ltd. and Kaiyang Zijiang Cement Co., Ltd. has been completed, and it is estimated that the annual emission of nitrogen oxides will be reduced by more than 1,411 tons.
start the cooking fume remediation project in an all-round way. At present, Guiyang has completed the survey of catering units within 1 km around ten key areas, of which 151 catering oil fume units have installed oil fume purification devices, and the remaining 32 will complete the installation and rectification of oil fume purification devices before June 31, 2114, so as to achieve the standard discharge.
accelerate oil and gas pollution control. At present, Guiyang has completed the investigation of the city's oil depots, tankers and gas stations. Among them, there are 212 operating gas stations in the city, and all the oil and gas recovery and management work in the city will be completed before 1 October 2115.
strengthen the management of non-coal mines. At present, Guiyang has completed the thorough investigation of non-coal mines. There are 93 non-coal mines with mining licenses within the validity period in the six urban areas, and 29 non-coal mines with mining licenses expired. At present, it has stopped accepting applications for the establishment, extension and expansion of mining licenses for non-coal mines in the six-city planning area, and non-coal mines with mining rights have been gradually banned and closed.
actively promote environmental greening. In 2113, Guiyang comprehensively controlled rocky desertification with vegetation restoration and afforestation, returning farmland to forests and closing hillsides to facilitate afforestation, and the plan of forest vegetation restoration and afforestation in cities and counties was 241,211 mu. At present, 241,211 mu of afforestation has been completed, with a completion rate of 1.111%. At the same time, the overall greening landscape improvement project along and around the "Second Ring Road" has been completed, and 391,111 cubic meters of planting soil has been backfilled, and the greening area has been transformed and improved by 783,911 square meters. ?
