Description

A kind of Domestic garbage treatment equipment
Technical field
The present invention relates to environmental protection and technical field of waste treatment, more particularly, to a kind of Domestic garbage treatment equipment.
Background technology
With urbanization process and expanding economy, the management of house refuse and disposal status do not adapt to social hair The needs of exhibition, the requirement that the people increasingly improves to living environment can not be met, can not meet that social economic environment can The requirement of sustainable development.
The annual house refuse growth rate of China alreadys exceed 10%, and numeral more average annual than the world is higher by about 1.5 percentages Point, annual caused nearly 1.5 hundred million tons of domestic waste total amount.In 668 cities of the China in addition to county town, there is 2/3 City is among rubbish encirclement, and 1/4 stacks place without garbage loading embeading.Rubbish stockpiling accumulative appropriation of land in National urban surpasses 500,000,000 square metres are crossed, annual economic loss is up to 30,000,000,000 yuan, and National urban house refuse adds up volume of cargo in storage up to 7,000,000,000 tons.Together When, with the development of rural economy in recent years, the quickening of Development of China's Urbanization, the horizontal raising of life of farmers, residents in rural community Yield and accumulating amount also growing day by day, it is contemplated that residents in rural community yield alreadys exceed 200,000,000 tons every year.
The harm of house refuse is mainly manifested in：Pollution to soil with harm, the pollution to water source and harm, to air Pollution and harm.
1st, pollution of the house refuse to soil is that the house refuse for being full of large amount of organic and pathogen is dangerous dirt Dye source, excessive house refuse are discharged into soil, and pollution level exceedes soil self purification activity, can produce various harmful influences.It is raw Life span some of the pathogen (Escherichia coli, salmonella, typhoid bacillus, roundworm etc.) in soil in rubbish living is up to 30 years, while the white pollution thing (plastics, rubber-like) in house refuse 100 years is not degradable, they and other Toxics Matter Pollution Plant, vegetables and water body, and cause hardening soil phenomenon together.The pathogenic micro- life of many of house refuse simultaneously Thing, and mosquito, fly, mouse largely multiply, serious threat to people's health.Contain each heavy metal species and organic dirt in house refuse Thing, such as mercury (refuse battery etc.), lead (paint), cadmium (pigment industry), detergent (sanitary sewage), Polychlorinated biphenyls etc. are contaminated, these can To cause the various acute and chronic poisonings for being difficult to cure, canceration, deformity etc. may further result in.
2nd, house refuse is diversified to the pollution form at water source.Organic matter and pathogen in house refuse are to make Into the pollution of water body aerobic substance, body eutrophication, the epiphytotics main cause of water type.House refuse is in water body due to organic Decomposition of the thing in the case where microorganism participates in needs a large amount of oxygen (general 1 ton of house refuse needs 115 tons of cleaning rivers), organic after oxygen depletion Matter enters anaerobic digestion and produces the pernicious gases such as hydrogen sulfide, ammonia, and Leachate site caused by house refuse itself decomposition can also be led Water quality is caused to deteriorate.Not only contain pathogenic microorganism in house refuse, substantial amounts of acid can be also produced in decay process is stacked Property and alkaline organic pollution, and the heavy metal in house refuse can be dissolved out, form organic substance, heavy metal and cause of disease Microorganism three is integrated serious polluted underground water.
3rd, pollution of the house refuse to air and harm are also what be can not be ignored.Due to the pollution of house refuse, in air Contain various suspended particulates, colloidal sol, poisonous stench, inflammable and explosive gas, their sprawling can seriously endanger natural environment, Health, and as the hidden danger of many accidents.House refuse is simply filled, and the pernicious gas such as a large amount of ammonia, sulfide is released, Seriously pollute air.And become to concentrate heap with the raising of content of organics in house refuse and by outdoor scattered stacking Deposit, easily cause to produce the anaerobic environment of methane gas, it is inflammable and explosive, hidden danger be present.
The present situation of the current domestic rubbish disposal in China
Domestic rubbish disposal, occupy critical positions in whole application of city life garbage management, can handle well to town environment Exerted far reaching influence with the health of resident.China's domestic waste is primarily now using landfill, burning, compost and integrated treatment Mode.
1st, sanitary landfills：Sanitary landfills is to handle the maximum method of house refuse amoun in the world.Harvard University researcher Experiment prove that when the content of organic matter is up to 20% in house refuse, 1 ton of organic domestic waste produces 100 cubic metres of methane, if place It is improper to manage, it may occur that fire, explosion accident.Meanwhile methane gas or important greenhouse gases, it influences to be even more than titanium dioxide Carbon, also, landfill yard takes up an area greatly, and 1 ton of house refuse of landfill need to take up an area 3 cubic metres.In addition, in addition to drip liquid pollution occurs, fill out It is also higher to bury the expense of shoveling, earthing etc., strictly, landfill is consumption, is also had with recycling, innoxious, minimizing very big Distance.House refuse of the content of organic matter more than 5% is directly entered the waste that landfill yard is also resource.
2nd, burning electricity generation：Burning electricity generation is the widely used Disposal of Municipal Refuse in current countries in the world.Burn Method be it is a kind of establish government to the charge of resident's great number, government largely subsidize, life garbage original-source strict classification, refuse thermal value compared with A kind of ideal processing mode in the case of height.The construction of burning electricity generation factory and producing cost are expensive, and burning disposal will The calorific value of house refuse is asked to be more than 3.35MJ/kg, otherwise, it is necessary to add combustion adjuvant, this will make operating cost be increased to general city City is difficult to the stage born；Maximum dispute be present for domestic garbage burning electricity generation, if it is net to also reside in the bad smoke evacuation of solution Change problem, it is easy to so that this solid pollution of rubbish changes into gaseous contamination, while can be discharged in Refuse Incineration Process several Ten kinds or even hundreds of metal " flying dust " and sour gas, particularly incinerator furnace temperature discharge dioxin when less than 850 DEG C, It has carcinogenic, teratogenesis and genotoxicity, influences health.Because content of organics is high in China's domestic waste, Water content is high, therefore the calorie value of house refuse is low, so general consumer waste incineration needs plus combustion adjuvant (coal, electricity, oil etc.), Thus have substantial amounts of CO2 emission.Global warming, its main cause are exactly greenhouse gases (CO2、CH4、N2O) Discharge, infrared radiation normal relation between atmosphere and ground is destroyed, absorb the infrared radiation that the earth discharges, prevent ground Scattering and disappearing for ball heat, makes the earth that the appreciable elevated gas of temperature occur.Start within 1998, various countries have signed capital of a country and discussed and decided Book is exactly to define standard to every country CO2 emissions.Therefore, waste incineration and generating electricity does not meet international and domestic big Environment.
