Question 8: Our country is full of garbage. How to dispose of it? Methods of garbage disposal
China is currently studying a new method of garbage disposal - resource utilization, which treats garbage harmlessly and produces composite fertilizers, bricks and composites. Building materials such as boards, and products such as electricity are currently a major difficulty.
In order to cooperate with resource utilization, China will subdivide urban waste into four groups, namely material waste group (including glass, magnetic or non-magnetic metals, waste paper, rubber, plastics), organic waste group (Kitchen waste, biological waste), inorganic waste group (stove ash, bricks, ceramics, etc.), toxic and hazardous waste group (wasted batteries, waste fluorescent lamp tubes, pesticide containers, expired drugs, medical waste and waste TV sets, Electronic waste from old electrical appliances such as phones and computers).
China’s urban garbage treatment started very late, and garbage treatment only began in the 1980s. Previously, garbage was piled in the open.
According to information from the Municipal Solid Waste Disposal Committee of the China Environmental Protection Industry Association, before 1990, China's urban waste disposal rate was less than 2%. After entering the 1990s, China's urban waste treatment has continued to improve. In 1999, there were 668 cities in China with 696 garbage treatment plants (fields), including less than 200 harmless treatment plants. The garbage treatment rate was 63.4%, and the harmless treatment rate was only 20.3%.
There are more than 700 harmless disposal sites for domestic waste in Chinese cities, and the national municipal solid waste disposal rate is 52%.
Garbage disposal in Chinese cities must first go through collection. At present, China's urban domestic waste collection method is basically mixed collection. Although the Chinese government promoted classified collection in 2002, classified collection currently only accounts for 16%.
There are three main methods of mixed collection. One is to place the collection containers in fixed locations, such as residential areas, both sides of streets, and other public places. Special sanitation personnel are responsible for collecting garbage in these containers every day. Second, there are fixed garbage collection stations in residential areas, and residents can throw household garbage to the garbage stations every day. The third is the garbage chute. In China's high-rise residential buildings, the garbage chute is already designed when the building is built. It runs from the first floor to the top floor. Residents can throw garbage into the garbage chute and sanitation personnel take it away from the bottom. Collecting household waste through garbage channels was once the most common way of collecting waste in residential areas. However, after the SARS outbreak in 2003, many cities banned them because garbage was conducive to the spread of bacteria. Cities such as Beijing, Guangzhou and Shanghai have successively stipulated that new residential buildings should not have garbage chute, and some cities have closed the garbage chute of existing residential buildings out of use.
The collected garbage is transported to the garbage transfer station by special garbage trucks. Garbage haulers are completely sealed. After the garbage is transported to the transfer station, it undergoes the first step of treatment. First, it is classified by a classification machine and divided into organic matter and inorganic matter, as well as usable and unusable matter. Large-volume garbage must also be compressed. Afterwards, the garbage is sorted and transported away.
Some of the garbage transported from the transfer station is transported to sanitary landfills. The garbage is filled into prepared pits, covered and compacted to cause biological, physical, and Chemical changes, decomposition of organic matter, to achieve the purpose of reduction and harmlessness. Special pipes and anti-seepage layers are laid in these pits to collect gas and leachate produced by garbage fermentation. The gas is burned, and part of the leachate is purified and processed into reclaimed water, which is used to clean garbage vehicles and ground dust. Some of the leachate is filtered and reaches the national first-class standard before being discharged, which will not cause pollution to the environment.
Others are transported to the composting plant. After composting, the domestic waste is turned into hygienic and odorless humus, which is used as fertilizer for plants.
Another part is sent to the incinerator for incineration, so that the combustible components in the garbage are fully oxidized, and the heat generated is used for power generation and heating. At present, there are 140 waste-to-energy power plants built, under construction, and being submitted for approval in China. One ton of garbage can generate 300 degrees of electricity, and the waste heat can also be used for heating. Tianjin Shuanggang Waste-to-Energy Power Plant has a daily processing capacity of 1,200 tons of waste and an annual power generation of 120 million kilowatt-hours, which can provide electricity for 50,000 households for a year, which is equivalent to saving 48,000 tons of standard coal.
For recyclable waste, it will be recycled and reused.
In the process of garbage disposal, China has formulated many relevant standards, such as agricultural control standards for urban garbage, sanitation standards for harmless feces, and incineration exhaust gas emission standards.
Among the current garbage disposal methods, incineration has been developing slowly in China, mainly due to lack of funds.
The initial investment in incineration treatment is relatively large, and it is necessary to build a garbage disposal capacity of 10 per day...>>
Question 9: How to deal with domestic waste in a more environmentally friendly way? Incineration is an efficient way to dispose of waste. However, there are currently many incinerators that burn garbage. The most ideal incinerators are "clean incineration technology" and "resource utilization law garbage incinerators".
The resource utilization method garbage incinerator is based on the three elements of material combustion and adopts fuzzy design techniques to achieve cooling, burning, and burning of garbage from bottom to top in a closed oxygen-deficient environment in the furnace. Through incineration processes such as carbonization, combustible gas generation, and drying, a large amount of carbon monoxide, hydrogen, methane and other carbohydrate-based combustible gases are obtained. These combustible gases are new energy sources for waste recycling. They have high thermal energy and can be replaced. Diesel and natural gas are used in the tail gas treatment tower behind the incinerator to incinerate the flue gas at high temperature and oxidize the toxic and harmful substances in the flue gas, thereby achieving the purpose of treating waste with waste, utilizing resources and protecting the environment. In July 2007, it won the national patent.
The resource utilization method garbage incinerator is a high-load, closed combustible gas generator without any odor or gas leakage. Without the need for diesel, heavy oil, mixed oil, or natural gas, the entire process of garbage dehydration, garbage gasification, and effective garbage incineration is comprehensively realized. It is a new technology, new process and new product for clean garbage incineration.
Waste incinerators under the Resource Utilization Law have been installed in Guangxi, Beijing, Shandong, Hebei, Guizhou, Shanxi, Sichuan, Inner Mongolia, Heilongjiang, Jiangsu, Jilin, Henan, Hubei, Tianjin, Xinjiang and other places in my country. Examples include waste incineration in areas such as living, hospitals, chemical industry, slaughtering, and food. A large number of applications have proven that the incineration effect is better than the national emission standards, and has won unanimous praise from users and experts. In August 2009, it was awarded Guizhou Province’s new energy-saving emission emission technology; in June 2010, it was awarded the National Innovative Product; in May 2010, it was awarded the National Torch Plan Product, with the following advantages:
(1) Application Wide range
The resource utilization method waste incinerator has a series of products such as single furnace incineration method, double furnace incineration method, three furnace incineration method and multi-furnace incineration method, which can meet the needs of large, medium and small towns, small towns, As well as rural domestic waste incineration and medical waste treatment.
(2) No need for fuel and gas, saving resources
The resource utilization method incinerator converts garbage into gas without using diesel, heavy oil, natural gas, liquefied gas, or coal gas. , the gas is burned in the oxidation tower behind the furnace to oxidize the flue gas, which greatly saves diesel or natural gas and reduces operating costs.
(3) Use waste to treat waste and utilize resources
The furnace can put all the waste generated every day into the furnace at one time and process it under closed conditions. The waste generates combustible gases. In addition to using these combustible gases for high-temperature oxidation of flue gas behind the furnace, extra-large garbage centers can also use the waste heat to boil water for bathing or drive turbine generators to generate electricity, thus achieving the goal of treating waste with waste. The purpose of resource utilization and circular economy.
(4) No dedicated personnel are required.
This furnace changes the traditional style of the past and eliminates the backward method of traditional incinerators that require frequent feeding of materials. All garbage enters the furnace at one time throughout the day. In a closed condition, after the garbage is ignited within 3 to 10 seconds, the garbage in the furnace automatically burns and decomposes into gas, and the gas is used to incinerate the flue gas and other processes. The entire process runs automatically without the need for dedicated personnel, saving operators time and effort.
(5). The equipment operates in a closed manner, without secondary pollution.
After the garbage is put into the furnace, it operates under a closed and slightly negative pressure. There is no odor leakage, no secondary pollution, and protection. It reduces the number of operators and is beneficial to the ecological environment of the hospital.
(6) No need to rotate the grate, reducing equipment failures
Garbage incineration is carried out under high temperature conditions. Any rotating equipment operating under high temperature conditions in the furnace has a high failure rate. The service life is short, so the furnace changes the outdated, backward and traditional combustion method. There is no need to rotate the grate, which eliminates mechanical failures under high temperature conditions and extends the life of the equipment.
(7) Save operating costs and reduce operating costs
In traditional incinerators, the operator stands next to the furnace and continuously, uninterruptedly and frequently pumps water into the furnace. Add garbage inside.
The operation is cumbersome and the management is complex. If the operator wants to add garbage into the furnace continuously, uninterruptedly and frequently, he must open the furnace door. As long as the furnace door is opened, the heat energy will overflow from the feed port and be radiated into the air, causing a waste of heat energy. , and once the furnace door is opened, toxic and harmful gases will be emitted from the furnace, causing direct physical and mental harm to the operators. Especially after the furnace door is opened, the toxic and harmful gases will overflow, forming toxic and harmful pollution to the surrounding environment, causing concentrated The sanitary place for disposal becomes a secondary pollution state, and the resource utilization method garbage incinerator operates in a closed manner without the use of diesel, heavy oil, mixed oil, natural gas, and coal gas...>>
