Description
Technical field
The present invention relates to a kind of consumer waste innocent comprehensive processing technique and device systems of the domestic waste comprehensive regulation.
Background technology
Along with the mankind's civilization construction and people enjoy when enriching material progress, all making, abandoning various house refuses every day, 1.5 hundred million tons of house refuses of the annual generation of China, and every year with 10% speed increase, and carry the germs of a disease in these rubbish, virus, the life that influence is human and biological destroys the ecological balance, disturb the stable of the Nature, the integrated treatment of domestic waste is imperative.The implication of Urban Domestic Waste Comprehensive Treatment: domestic waste must be accomplished " minimizing, resource, innoxious ", and rubbish must accomplish that in the integrated treatment process " zero-emission, non-secondary pollution, rubbish are all eliminated " general at present waste disposal method that adopts has following three kinds:
1. landfill method
Utilize hole ditch or hillside fields to scrape out zanjon and carry out waste deposit, and carry out air guide, water conservancy diversion processing.The earth backing of one deck rubbish one deck 25-50 centimetre when landfill arrives certain altitude, adds 100 centimeters thick soil stratums and compacting above.Easily produce a large amount of harmful and inflammable gases in landfill and stacking process, and take up an area of, polluted source is easily blasted and personal injury accident.Method not according to the national regulation landfill is the waste disposal method that country forbids at present.
2. composting process
This law is with refuse collection, utilizes microorganism to become thoroughly decomposed under uniform temperature and acidity condition, makes it become fertilizer.Though method is simple, cost is also lower, and is abominable in the composting plant surrounding environment, can cause serious secondary pollution to environment, and complaints are heard everywhere for the masses around the rubbish factory, and dispute is continuous.Therefore select this method difficulty big, comprehensive utilization of resources is poor.
3. waste incineration or burning electricity generation
The burning electricity generation method is commonplace a kind of way in present developed country's garbage disposal abroad.At home, recently also just a few cities living standards of the people reach or adopt the burning electricity generation method near the city of the level of medium-developed country.But, according to the national conditions of China, in general, the small city house refuse generally has following characteristics, the refuse moisture height, inorganic content height, rubbish mixed collection, waste incineration and generating electricity is not accomplished whole treatment zero drainings to rubbish, and this is the maximum drawback of waste incineration and generating electricity; Calorific capacity is low, generally is lower than below 50% of developed country; Burning electricity generation can cause secondary pollution to environment, in the process of waste incineration, can produce a large amount of harmful substance and gas, especially the chemical substance of " dioxin ", be documented in according to present data in the process of burning electricity generation, also do not obtain basic improvement, waste incineration and generating electricity can burn partly rubbish and handle in addition, and the part that cannot burn is not resolved, also need landfill, thereby we think that waste incineration and generating electricity has only solved subproblem, and are also unresolved to the problem of incombustible part; Present domestic component of refuse complexity, loading in mixture, waste incineration and generating electricity system are extremely unstable, so be difficult to accomplish to be incorporated into the power networks in the electric power system in city, so waste incineration and generating electricity can not get selling, and guarantees that Business survival has any problem; Waste incineration and generating electricity is currently used all to be overseas equipment, the equipment manufacturing cost costliness, a common garbage incinerating power plant investment needs more than one hundred million units, maintenance cost is surprising especially, and foreign investment needs government guarantee, government's pressure is huge like this, and investment is seriously disproportionate with recovery, and the possibility of profit is less; For small and medium-sized cities, simple waste incineration is difficult to thoroughly solve to secondary pollution, and burning electricity generation does not also have very successful example at present, and relevant authorities of country are especially as promoting object.In a word, said method is sheerly single dissolves, and can not meet innoxious, minimizing, resource environmental requirement index.
Summary of the invention
