Question 8: How do we deal with the garbage in our country? Garbage disposal mode
At present, China is studying a new way of garbage disposal-resource utilization. Garbage is treated harmlessly and recycled to produce compound fertilizer, bricks, composite boards and other building materials, as well as electricity and other products.
At present, garbage classification is a big difficulty.
In order to cooperate with resource utilization, China divides urban garbage into four categories, namely, material garbage (including glass, magnetic or non-magnetic metals, waste paper, rubber and plastics), organic garbage (kitchen garbage and biological garbage) and inorganic garbage (furnace slag, bricks and tiles, ceramics, etc.). ) and toxic and harmful waste groups (waste batteries, waste fluorescent tubes, pesticide containers, expired drugs, medical waste and waste).
China's urban garbage treatment started very late, and it didn't start until 1980s. In the past, garbage was piled up in the open air.
According to the data of the Municipal Solid Waste Treatment Committee of China Environmental Protection Industry Association, before 1990, the municipal solid waste treatment rate in China was less than 2%. Since the 1990s, the level of urban garbage disposal in China has been continuously improved. From 65438 to 0999, there were 668 cities and 696 garbage treatment plants (sites) in China, including less than 200 harmless treatment plants. The garbage disposal rate is 63.4%, and the harmless disposal rate is only 20.3%.
There are more than 700 harmless treatment plants for municipal solid waste in China, and the harmless treatment rate of municipal solid waste in China is 52%.
Garbage disposal in China should be collected first. At present, the collection method of municipal solid waste in China is basically mixed collection. Although China advocated classified collection in 2002, it currently only accounts for 16%.
There are three main ways of mixed collection. One is to put the collection containers in fixed places, such as residential areas, streets and other public places. Every day, special sanitation personnel are responsible for collecting the garbage in these containers. Second, there are fixed garbage collection stations in residential areas, and residents can throw their domestic garbage into the garbage stations every day. The third is the garbage chute. In China's high-rise residential buildings, the garbage chute was designed when the building was built, from the first floor to the top floor. Residents can throw the garbage into the garbage chute, and the sanitation personnel take it away from the ground floor. Collecting domestic garbage through garbage tunnels was once the most common garbage collection method in residential areas. However, after the outbreak of SARS in 2003, garbage tunnels were banned in many cities because they were conducive to the spread of bacteria. Beijing, Guangzhou, Shanghai and other cities have successively stipulated that garbage lanes should not be set up in new houses, and some cities have also closed garbage lanes in existing houses.
The collected garbage is transported to the garbage transfer station by a special garbage truck. The garbage truck is completely sealed. After the garbage is transported to the transfer station, it needs to be treated in the first step. First of all, it is classified by classifier, which is divided into organic and inorganic, usable and unusable. It is necessary to compress the large-capacity garbage. After that, the garbage is sorted and transported away.
Part of the garbage transported from the transfer station is transported to the sanitary landfill, and the garbage is filled into the prepared pit, covered and compacted, so that it will undergo biological, physical and chemical changes and decompose organic matter to achieve the purpose of reduction and harmlessness. These pits are paved with special pipes and impervious layers to collect the gas and leachate produced by garbage fermentation. After gas combustion, some leachate is purified into reclaimed water, which is used to clean garbage vehicles and ground dust. Some leachate will be discharged after reaching the national first-class standard after filtration, which will not cause pollution to the environment.
Others are transported to composting plants. After composting, domestic garbage becomes sanitary and odorless humus, which is used as fertilizer for plants.
Part of it is sent to the incinerator for incineration, so that the combustible components in the garbage are fully oxidized, and the generated heat is used for power generation and heating. At present, there are 140 garbage power plants built, under construction and being submitted for approval in China. A ton of garbage can generate 300 degrees of electricity, and the waste heat can also be used for heating. Tianjin Shuang Gang Garbage Power Plant has a daily garbage disposal capacity of 1.200 tons and an annual power generation capacity of1.200 million kWh, which can supply power to 50,000 households for one year, equivalent to saving 48,000 tons of standard coal.
For recyclable garbage, it will be recycled.
In the process of garbage disposal, China has formulated many relevant standards, such as the agricultural control standard of urban garbage, the sanitary standard of harmless feces, and the emission standard of incineration waste gas.
Among the current garbage disposal methods, incineration develops slowly in China, mainly due to the shortage of funds. The investment in the early stage of incineration treatment is large, and the daily garbage treatment capacity is 10 ... >; & gt
Question 9: How to deal with domestic garbage is more environmentally friendly? Incineration is an effective method to treat garbage. However, there are many incinerators for burning garbage at present, and the most ideal incinerators are "clean incineration technology" and "garbage incinerator with resource utilization mode".
Based on the three elements of material combustion, the waste incinerator with resource utilization method adopts fuzzy design method to make the waste cool, burn out, carbonize, produce combustible gas and dry from bottom to top in the closed oxygen-deficient environment in the furnace, and then obtain a large number of combustible gases mainly composed of carbon monoxide, hydrogen, methane and other carbohydrates. These combustible gases are new energy sources for waste regeneration, which have high heat energy and can replace diesel oil and natural gas. The tail gas treatment tower used after the incinerator burns the flue gas at high temperature and oxidizes the toxic and harmful substances in the flue gas to achieve the purpose of treating waste with waste, utilizing resources and protecting the environment, and obtained the national patent in July 2007.
The waste incinerator with resource utilization method is a kind of combustible gas generator with high load, sealing, no odor overflow and no gas leakage. Without diesel oil, heavy oil, mixed oil and natural gas, the whole process of garbage dehydration, garbage gasification and garbage effective incineration is realized comprehensively. It is a new technology, new process and new product for clean incineration of garbage.
In China, Guangxi, Beijing, Shandong, Hebei, Guizhou, Shanxi, Sichuan, Inner Mongolia, Heilongjiang, Jiangsu, Jilin, Henan, Hubei, Tianjin, Xinjiang and other places have already had engineering examples of recycling waste incinerators, involving waste incineration in the fields of life, hospitals, chemicals, slaughter and food. A large number of applications have proved that the incineration effect is better than the national emission standard, which has won unanimous praise from users and experts. In August 2009, it obtained the new technology of energy saving and drainage in Guizhou Province; On June 20 10, national innovative products were obtained; Products of the National Torch Program were obtained in May 20 10, which has the following advantages:
(1), which has a wide range of applications.
Resource utilization mode Waste incinerators have a series of products, such as single furnace incineration, double furnace incineration, three furnace incineration and multiple furnace incineration, which can meet the needs of domestic waste incineration and medical waste disposal in large, medium and small towns, small towns and rural areas.
(2) Do not use fuel and gas, and save resources.
The incinerator is used as a resource to convert garbage into fuel gas, without diesel oil, heavy oil, natural gas, liquefied gas and gas. The fuel gas burns oxidized flue gas in the oxidation tower behind the incinerator, which greatly saves diesel oil or natural gas and reduces the operating cost.
(3) Treating waste with waste and recycling.
The furnace can send all the wastes generated every day into the furnace at one time, and generate combustible gas from these wastes under closed conditions. These combustible gases are not only used for high-temperature oxidation of flue gas behind the furnace, but also used for boiling water for bathing in super-large garbage centers or promoting turbine generators to generate electricity, so as to achieve the purposes of treating waste with waste, utilizing resources and recycling economy.
(4) Don't be on duty.
The furnace has changed the traditional style and put an end to the backward method that traditional incinerators need frequent feeding. It uses all garbage to enter the furnace at one time all day, and after the garbage is ignited within 3 ~ 10 seconds under closed conditions, the garbage in the furnace is automatically burned and decomposed into gas, which is used in the whole process of burning flue gas. The whole process runs automatically, without special person on duty, and the operator saves time and effort.
(5) The equipment is closed without secondary pollution.
After the garbage enters the furnace, it runs in a closed micro-negative pressure state, without odor overflow and secondary pollution, which protects the operators and is beneficial to the ecological environment of the hospital.
(6) There is no need to rotate the grate, thus reducing equipment failures.
Garbage incineration is carried out at high temperature, and any rotating equipment has high failure rate and short service life at high temperature in the furnace. Therefore, the furnace has changed the outdated, backward and traditional incineration mode without rotating grate, eliminated the mechanical failure at high temperature and improved the service life of the equipment.
(7), save operating costs, reduce operating costs.
In the traditional incinerator, the operator stands next to the furnace and continuously, uninterruptedly and frequently throws garbage into the furnace. Operators with complicated operation and management must open the furnace door if they want to throw garbage into the furnace continuously, uninterruptedly and frequently. Only when the oven door is opened, the heat energy will overflow into the air from the inlet, resulting in a waste of heat energy. In addition, once the oven door is opened, toxic and harmful gases will be emitted in the oven, causing direct physical and mental harm to operators, especially after the oven door is opened, toxic and harmful gases will overflow, causing toxic and harmful pollution to the surrounding environment. Centralized disposal of sanitary places has become a state of secondary pollution, while the garbage incinerator with resource utilization mode is closed, and there is no diesel oil, heavy oil, mixed oil, natural gas and gas. & gt
