Description

Domestic garbage treating system

Technical field

The present invention relates to environmental protection and technology of garbage disposal field, especially relate to a kind of domestic garbage treating system.

Background technology

Along with urbanization process and expanding economy; The management of house refuse and processing present situation can not adapt to demands of social development; Can not satisfy the requirement that the people improves living environment day by day, more can not satisfy the requirement of social economic environment sustainable development.

The annual house refuse growth rate of China surpasses 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 that produces.In 668 cities of China except that the county town, have 2/3 city to be among rubbish surrounds, 1/4 has not had garbage loading embeading stacking place.National urban rubbish is stored up the accumulative total appropriation of land and is surpassed 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.Simultaneously, along with 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 every year is above 200,000,000 tons.

The harm of house refuse mainly shows: to the pollution of soil and harm, to contaminated water source and harm, to the pollution and the harm of 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 surpasses soil self purification activity, can produce various injurious effects.What the life span of pathogen (Escherichia coli, salmonella, typhoid bacillus, roundworm etc.) in soil in the house refuse had reaches 30 years; White pollution thing (plastics, rubber-like) in the house refuse all was difficult for degraded in 100 years simultaneously; They pollute plant, vegetables and water body together with other noxious material, and cause hardening soil phenomenon.Simultaneously in the house refuse many pathogenic microorganisms are arranged, and mosquito, fly, mouse multiply in a large number, serious threat is to people's health.Contain each heavy metal species and organic pollution in the house refuse; For example mercury (refuse battery etc.), plumbous (paint), cadmium (pigment already), washing agent (sanitary sewage), Polychlorinated biphenyls etc.; These can cause the various acute and chronic poisonings that are difficult to cure, and can also cause canceration, deformity etc.

2, house refuse is diversified to the contaminated water source form.Organic matter in the 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 needs a large amount of oxygen (general 1 ton of house refuse needs 115 tons and cleans rivers) because organic matter is participated in decomposition down in microorganism in water body; Organicly behind the oxygen depletion get into anaerobic digestion and produce pernicious gases such as hydrogen sulfide, ammonia, house refuse self is decomposed oozing drop liquid and also can causing water quality to worsen of producing.Not only contain pathogenic microorganism in the house refuse; In stacking decay process, also can produce a large amount of acidity and alkaline organic pollution; And can the heavy metal in the house refuse be dissolved out, forming organic substance, heavy metal and pathogenic microorganism three is the serious polluted underground water of one.

3, house refuse also can not be ignored with harm the pollution of atmosphere.Because the pollution of house refuse, contained various suspended particulates, colloidal sol, poisonous stench, inflammable and explosive gas in the air, spreading of they can the serious harm natural environment, health, and becomes the hidden danger of many accidents.The simple and easy landfill of house refuse, pernicious gases such as a large amount of ammonia, sulfide are released, severe contamination atmosphere.And become concentrated storing up along with the raising of content of organics in the house refuse with by open-air dispersion stacking, very easily cause the anaerobic environment that produces methane gas, inflammable and explosive, there is hidden danger.

The present situation of the present domestic rubbish disposal of China

Can domestic rubbish disposal occupies critical positions in whole application of city life garbage management, handle well the health to town environment and resident is exerted far reaching influence.The main now mode that adopts landfill, burning, compost and integrated treatment of China's domestic waste.By on September 26th, 2010, the whole nation was established city, city, county and part cities and towns and is built together into 849 of domestic garbage was harmlessly treated facilities, and wherein sanitary filling field is 676,7 of composting plants, 90 of incineration plant, 76 in integrated treatment factory.Disposal ability 399702 ton per days, sanitary landfills 281927 ton per days wherein, compost 1950 ton per days burn 68865 ton per days, integrated treatment 46960 ton per days.

1, sanitary landfills: sanitary landfills is to handle the maximum method of house refuse amount in the world.The researcher's of Harvard University evidence, the content of organic matter reaches at 20% o'clock in the house refuse, and 1 ton of organic domestic waste produces 100 cubic metres in methane, if deal with improperly, meeting breaking out of fire, explosion accident.Simultaneously, methane gas still is important greenhouse gases, its influence even surpass carbon dioxide, and landfill yard takes up an area of big, and 1 ton of house refuse of landfill need be taken up an area of 3 cubic metres.In addition, except taking place drop liquid pollutes, the expense of landfill shovelings, earthing etc. is also higher, says that strictly landfill is to dissolve, with resource, innoxious, minimizing very big distance in addition.The content of organic matter directly gets into the waste that landfill yard also is a resource greater than 5% house refuse.

2, burning electricity generation: burning electricity generation is the garbage treatment technology that extensively adopt present countries in the world.Burning method be a kind of be based upon government to resident's great number charge, government subsidize in a large number, a kind of comparatively desirable processing mode under the strict classification of life garbage original-source, refuse thermal value condition with higher.The construction of burning electricity generation factory and producing cost are expensive, and burning disposal requires the calorific value of house refuse 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, the metal " flying dust " and the sour gas, particularly incinerator furnace temperature that can discharge simultaneously tens kinds and even hundreds of in the waste incineration process discharge dioxin less than 850 ℃ the time; It has carcinogenic, teratogenesis and genotoxicity, influences health.Because content of organics is high in China's domestic waste, water content is high, so the calorie value of house refuse is low, so general consumer waste incineration need so just have a large amount of CO2 emissions with combustion adjuvant (coal, electricity, wet goods).Global warming; Its main cause is exactly greenhouse gases (CO2, CH4, N2O) dischargings, destroys infrared radiation normal relation between atmosphere and ground, absorbs the infrared radiation that the earth discharges; Stop scattering and disappearing of earth heat, make the earth that the gas that appreciable temperature raises take place.Beginning in 1998, various countries have signed the Kyoto Protocol and exactly each national CO2 emissions have been stipulated standard.Therefore, waste incineration and generating electricity does not meet international and domestic overall situation.
