Description

Life refuse processing method

Technical field

The present invention relates to the one way of life waste disposal method, relate in particular to a kind of rapid, innoxious, without the Prediction for Solid Waste Treatment Technology of residueization, resource circulation utilization, industrialization.

Background technology

According to statistics, China has 2/3 city to be absorbed in the predicament of garbage-surrounded city at present approximately.China is 1.5 hundred million tons nearby of the annual productions of domestic waste only, and these domestic waste overwhelming majority are air storages.It not only affects urban look, has polluted simultaneously and the vital atmosphere of our life, water and soil, and town dweller's health is consisted of very large threat, and rubbish has become in urban development, the social progress process one very thorny problem.And improving constantly along with living standards of the people, the quantity that house refuse produces is increasing, growth rate more and more faster (speed increment with annual 6%), composition becomes increasingly complex, the harm of bringing for the people's life is also more and more serious, and this has been the beyond dispute fact.

At present, domestic garbage disposal does not also have a kind of good solution.That now generally adopts has three kinds of methods: the one, and landfill; The 2nd, burn and burning electricity generation; The 3rd, compost.Now make a concrete analysis of as follows:

First method: landfill; Adopt at present maximum waste disposal methods.This method seems simply, but harm is very large.Its shortcoming is:

(1) floor space is large, service time is short (about general ten years), holding time long (can't recycle in 100 years);

(2) rubbish behind the landfill causes severe contamination to soil, underground water, atmosphere, and its reality harm and potential hazard are especially in continuous increase.

(3) garbage loading embeading has caused the serious waste of resource.

The waste disposal method of this landfill be a kind of helpless, do not have the processing method processed.We have progressively recognized the seriousness of problem, have many places all seeking active and effective waste disposal method.

Second method: burn and burning electricity generation.This method surface seems minimizing and the resource that has realized garbage disposal, but investigates China is built and go into operation burning or burning electricity generation destructor plant, will find that this processing method also is a kind of processing method that loses more than gain in fact.

(1) as if at first see its minimizing, the waste incineration decrement has been seen 50%～60% in the surface, but in fact remaining 40%～50% slag still needs to process again, still will go to follow the track of an overturned cart of burying method, the underground water and soil of recontamination again;

(2) see again its resource, directly burn and just need not say, because this method just do not realize resource more not realizing industrialization at all, the valuable resource that has been serious waste on the contrary.We singly say the resource of waste incineration and generating electricity at this, and this Technology origin is in abroad, and technology is comparative maturity also, but after introducing China, because operating cost is expensive, government finance is unable to be born, the landfill of being obliged to go again at last after many local operations.Its main cause is that the component of refuse of China is complicated, calorific value is low, moisture is large, causes incinerator to work.Want so normal operation, just necessary coal or oil spout have just increased operating cost so virtually, make to drop into to be far longer than output.And if the calorific value organic matter low, that moisture is large that accounts for rubbish total amount 50%～60% is separated compost, light burns high heating value rubbish, but of poor quality because of composting production, not welcome by the peasant, does not have market prospects, causes the organic matter secondary to stack and pollutes.

(3) in addition, burn and the burning electricity generation technology in Refuse Incineration Process, the toxic gas that discharges, such as the mercuryvapour in dioxin, the battery etc., the severe contamination atmosphere is processed this type of toxic gas, operating cost is very expensive again, does not tally with the national condition.So in the long term, this method does not meet innoxious, the resource of garbage disposal, the industrialization policy direction of country yet.

The third is compost, and the method has small investment, easy-operating advantage.But exist shortcoming:

(1) the rotten time of organic matter heap long, generally need three thoughtful one month, pile up seriously pollutedly, fly, mosquito multiply, the severe contamination surrounding enviroment are brought very big hidden danger to local health and epidemic prevention.

(2) organic matter degradation is not thorough, processes insufficiently, and residue still can cause refuse pollution.

(3) organic matter composting production impurity is many, and can not effective separation to harmful substances such as heavy metals, uses for a long time composting production, can cause the soil surface deposition, spoiled soil, harms the crops.

(4) in the composting process, most of nitrogen nutritions are by Spontaneous release, and the compounds such as phosphorus, potassium are by natural degradation, so cause fertilizer quality low, vast farmers is reluctant to make inquiries, and market prospects are remote.

In sum, the present Prediction for Solid Waste Treatment Technology of China is in low level substantially, is difficult to realize innoxious, the resource of garbage disposal, let alone industrialization.

Summary of the invention

Technical problem solved by the invention is the defective that overcomes prior art, provide that a kind of land occupation area is little, the processing time is short, avoid polluting, operating cost is low, effectively process pernicious gas, the institute's product quality of producing height, without the life refuse processing method of residue, non-secondary pollution, complete resource, thorough industrialization.
