Description
Technical field
The present invention relates to a kind of refuse disposal system, relate in particular to one way of life rubbish fermentation system.
Background technology
Along with the fast development of human society, population increase, economically developed, material life is more and more abundanter, and people's standard of living improves constantly, but the consequent is domestic refuse spreads unchecked, the global problem of contaminate environment is more and more serious.One seems simple question like this, has brought threat but to ecotope and the mankind's living environment, and the processing of domestic refuse is extremely urgent.Up to the present domestic rubbish disposal also rests on landfill and burns in these two kinds for the treatment of processs, and these two kinds of processing modes all have pollution problem, location resident's strong reaction in each refuse tip, and mass-meeting parade contentious case takes place frequently.Moreover, for topsoil and water pollution, be directly to have influence on the healthy of people, have influence on descendants's existence problem.So the treatment process of domestic refuse need to reasonably be gone development and utilization, should not produce again secondary pollution.
The following method of the general employing of existing domestic rubbish disposal:
1, garbage compost method:
Open type static compost---be the treatment process of least cost the earliest.It is directly stacked domestic refuse, fermentation, for plantation.But owing to having in rubbish, bury for a long time the nuisance being stale-proof, acid-base class material, is harmful to soil, is unfavorable for crop growth, and fertilizer efficiency is low.
Dynamic high temperature compost---this method adopts professional equipment after organic (can be rotten) refuse breaking, to concentrate and to ferment, and adds the special microorganism of cultivating, and organic matter is wherein degraded, and forms compost.This fertilizer is conducive to improve soil, and increasing both production and income also reaches nuisanceless, greenization, but single compost is difficult to the cost of recouping the investment, and impel the inorganics in rubbish to digest nowhere, finally still with land-fill method, remaining inorganics is carried out to landfill.In a word, the composting process production cycle is long, and the foul odour infringement surrounding environment in treating processes and work employee's is healthy, and quality is unstable, and objectionable impurities exceeds standard, can not be for farmland.The domestic most of composting plants that build up, in fact all can not normally move in recent years.
2, consumer waste filling and embedding method:
The pollution of household refuse landfill sites is mainly reflected in atmospheric pollution and water pollution.Early stage domestic rubbish disposal is simple and easy landfill or simple and easy stacking, such method of disposal is the most dangerous, because do not lay antiseep facility and safe disposal, foul smell flies away all over the sky, sewage crossing current, be polluted air polluted underground water source again, the crowd who around lives is encroached on, cancer village increasing year by year, the illness such as respiratory tract disease, lung cancer takes place frequently, and the unpleasant common people's resentment of foul smell sound is continuous.
Refuse landfill has endangered HUMAN HEALTH, has destroyed again Soil structure and Water quality, has also taken a large amount of land resources, should handle early the pollution problem of refuse landfill well.
3, domestic garbage burning electricity generation method:
Domestic garbage burning electricity generation is a kind of high pollution and processing mode that resource has all been burnt, because contained complicated in domestic refuse, the inside has organism and inorganics to mix to exist, and moisture content is large, and burning-point is low.If use separately domestic refuse to do combustionmaterial, be difficult to, so, when burning, must add some and help right material, so, will use some diesel oil, coal equal energy source.Rubbish has been burnt, and rubbish has obtained decrement, but resource has also been wasted.Moreover, rubbish also can produce toxic gas and lime-ash when burning, and in toxic gas, toxicity of dioxin is 900 times of arsenic, 130 times of prussiate; The particle ratio nano of dioxin is also little, once enter human body, cannot degrade and discharge, and be generally acknowledged carcinogens, be known as " poison in century ".
In a word, the actual effect of above three kinds of life refuse processing methods is to complete the processing requirements of resource utilization, innoxious, minimizing and cleanup standard, also seriously polluted, will damage ecotope, infringement HUMAN HEALTH.
Summary of the invention
The problems referred to above that exist for existing life refuse processing method, the main purpose of technical scheme provided by the invention is:
A kind of domestic refuse fermentation system that rubbish produces biogas that decomposes is provided.
To achieve these goals, the present invention has adopted following technical scheme:
