Description
Technical field
The present invention relates to environmental protection and technology of garbage disposal field, especially relate to one way of life refuse disposal system.
Background technology
Along with urbanization process and expanding economy, the management of house refuse and processing present situation can not adapt to the needs of social development, can not meet the requirement that the people improves day by day to living environment, more can not meet the requirement of social economic environment sustainable development.
The annual house refuse growth rate of China has exceeded 10%, exceeds about 1.5 percentage points than the average annual numeral in the world, nearly 1.5 hundred million tons of the annual domestic waste total amounts producing.In 668 cities of China except county town, have 2/3 city among rubbish surrounds, 1/4 without garbage loading embeading stacking place.National urban rubbish is stored up accumulative total appropriation of land and is exceeded 500,000,000 square metres, and annual economic loss is up to 30,000,000,000 yuan, and National urban house refuse accumulative total volume of cargo in storage has reached 7,000,000,000 tons.Meanwhile, along with the development of rural economy in recent years, the quickening of Development of China's Urbanization, the raising of life of farmers level, the output of life in the countryside rubbish and accumulating amount are also growing with each passing day, and estimate that life in the countryside refuse production has exceeded 200,000,000 tons every year.
The harm of house refuse is mainly manifested in: the pollution and harm to soil, the pollution and harm to water source, pollution and harm to atmosphere.
1, house refuse is the pollution of soil, and the house refuse that is full of large amount of organic and pathogen is dangerous pollution sources, and too much house refuse enters soil, and pollution level exceedes soil self purification activity, can produce various injurious effects.What the life span of the pathogen (Escherichia coli, salmonella, typhoid bacillus, roundworm etc.) in house refuse in soil had reaches 30 years, white pollution thing (plastics, rubber-like) in house refuse is all difficult for degraded for 100 years simultaneously, they and other noxious material together Pollution Plant, vegetables and water body, and cause hardening soil phenomenon.Simultaneously in house refuse, have many pathogenic microorganisms, and mosquito, fly, mouse multiply in a large number, serious threat is to people's health.In house refuse, contain each heavy metal species and organic pollution, such as mercury (refuse battery etc.), plumbous (paint), cadmium (pigment industry), washing agent (sanitary sewage), Polychlorinated biphenyls etc., these can cause the various acute and chronic poisonings that are difficult to healing, can also cause canceration, deformity etc.
2, house refuse is diversified to the pollution form at water source.Organic matter in house refuse and pathogen are to cause the pollution of water body aerobic substance, body eutrophication, the epiphytotics main cause of water type.House refuse in water body because the decomposition of organic matter under microorganism participates in needs a large amount of oxygen (general 1 ton house refuse need 115 tons of clean rivers), after oxygen depletion, organic matter enters anaerobic digestion and produces the pernicious gas such as hydrogen sulfide, ammonia, house refuse self decompose produce ooze drop liquid also can cause water quality worsen.In house refuse, not only contain pathogenic microorganism, in stacking decay process, also can produce a large amount of acidity and alkaline organic pollution, and the heavy metal in house refuse can be dissolved out, form organic substance, heavy metal and pathogenic microorganism three and be integrated serious polluted underground water.
3, house refuse also can not be ignored the pollution and harm of atmosphere.Due to the pollution of house refuse, in air, contain various suspended particulates, colloidal sol, poisonous stench, inflammable and explosive gas, spreading of they can serious harm natural environment, health, and becomes the hidden danger of many accidents.The simple and easy landfill of house refuse, the pernicious gases such as a large amount of ammonia, sulfide are released, severe contamination atmosphere.And stack to become to concentrate along with the raising of content of organics in house refuse with by outdoor dispersion and store up, very easily cause the anaerobic environment that produces methane gas, inflammable and explosive, there is hidden danger.

Can domestic rubbish disposal occupies critical positions in whole application of city life garbage management, handle well and will town environment and resident's health be exerted far reaching influence.China's domestic waste is the main mode that adopts landfill, burning, compost and integrated treatment now.By on September 26th, 2010,849 of domestic garbage was harmlessly treated facilities were built together in national the planned city, county and Some Cities And Towns, wherein 676 of sanitary filling fields, 7 of composting plants, 90 of incineration plant, 76, integrated treatment factory.Disposal ability 399702 ton per days, wherein sanitary landfills 281927 ton per days, compost 1950 ton per days, burn 68865 ton per days, integrated treatment 46960 ton per days.
1, sanitary landfills: sanitary landfills is the method for processing in the world house refuse amount maximum.The researcher's of Harvard University evidence, when in house refuse, the content of organic matter reaches 20%, 1 ton of organic domestic waste produces 100 cubic metres, methane, if deal with improperly, meeting breaking out of fire, explosion accident.Meanwhile, methane gas or important greenhouse gases, its impact even exceedes carbon dioxide, and landfill yard takes up an area large, and 1 ton of house refuse of landfill need be taken up an area 3 cubic metres.In addition, except occurring drop liquid pollutes, the expense of landfill shovelings, earthing etc. is also higher, strictly says, landfill is to dissolve, with resource, innoxious, minimizing very large distance in addition.The content of organic matter is greater than 5% house refuse and directly enters the waste that landfill yard is also resource.
2, burning electricity generation: burning electricity generation is the Disposal of Municipal Refuse that current countries in the world extensively adopt.Burning method is that a kind of government that is based upon is to a kind of comparatively desirable processing mode in resident's great number charge, government subsidizes in a large number, life garbage original-source is strictly classified, refuse thermal value is higher situation.The construction of burning electricity generation factory and producing cost costliness, burning disposal requires the calorific value of house refuse to be greater than 3.35MJ/kg, otherwise, must add combustion adjuvant, this will make operating cost be increased to the stage that general city is difficult to bear; Exist maximum to dispute on for domestic garbage burning electricity generation, also be if solve bad smoke evacuation purifying problem, be easy to make this solid pollution of rubbish to change into gaseous contamination, in Refuse Incineration Process, can discharge tens kinds and even hundreds of metal " flying dust " and sour gas simultaneously, particularly incinerator furnace temperature discharges dioxin in the time being less than 850 DEG C, it has carcinogenic, teratogenesis and genotoxicity, affects health.Because content of organics in China's domestic waste is high, water content is high, and therefore the calorie value of house refuse is low, so general consumer waste incineration need to, with combustion adjuvant (coal, electricity, wet goods), so just have a large amount of CO2 emissions.Global warming, its main cause is exactly greenhouse gases (CO2, CH4, N2O) discharges, destroy infrared radiation normal relation between atmosphere and ground, absorb the infrared radiation that the earth discharges, stop scattering and disappearing of earth heat, make the earth that the gas that appreciable temperature raises occur.1998 start, and various countries have signed the Kyoto Protocol and exactly every country CO2 emissions specified to standard.Therefore, waste incineration and generating electricity does not meet international and domestic overall situation.
