Description
Technical field
The present invention relates to environmental technology field, more specifically, it relates to life-garbage comprehensive treatment technology.
Background technology
Current Prediction for Solid Waste Treatment Technology both domestic and external, turns to target with innoxious, minimizing, resource, the most frequently used
Processing method mainly has landfill, burning and compost, the use range and condition that they have nothing in common with each other, from the angle point of recycling economy
Analysis, only it is managed from the overall process of source caused by rubbish, collection, transport and processing, could veritably accomplishes rubbish
Innoxious, minimizing and recycling.
Until current, domestic many cities and towns are still using the method simply stacked, because rubbish is a kind of extremely complex give up
Thing, due to biodegradable and chemical action, it can gradually rot over time and biodegradable, there is serious harm
Percolate and the biogas for having explosion potential, percolate are also possible to further polluted underground water, and the health to humans and animals causes
Serious threat.Sanitary landfill method, landfill yard bottom and around be covered with impervious material, and lay and catchment with weeper drain to arrange
Go out percolate, can solve the problems, such as leachate contamination underground water.But the biodegradable component of current China townm refuse contains
Amount is high, water content is big, directly uses landfill disposal method, and cost of transportation is high, and land occupation area is big, and landfill process will produce big
Percolate is measured, processing percolate difficulty is big；Composting process can be made perishable organic matter by aerobic or anaerobic composting method
Debirs are cured and stabilized, and kill harmful levels of pathogens and worm's ovum, innoxious so as to reach, and organic nutrient soil can be made,
But compost is only applicable to the organic wastes such as biodegradable food waste, domestic rubbish generally uses mixed collection, directly adopted at present
Cause compost impurity content height, fertilizer efficiency too low with compost treatment technology, can not apply；Burning method is a kind of high-temperature process of rubbish
Technology, its great advantage are that minimizing and innoxious degree are higher, and heat caused by burning can be used for generating electricity and heat supply, residue can
Directly fill, the volume and weight of waste can be greatly reduced, at present the modernization of developed country and domestic economy prosperity abroad
City is all widely used, but burning method requires higher to the calorific value of rubbish, and the situation of the most of townm refuses in China is uncomfortable
Close and carry out direct burning disposal.And high-moisture percentage waste of low heating value easily produces the pollutants such as dioxin in burning process,
Operating cost is high.
In view of the actual characteristic and sanitary landfills of China's rubbish, the respective limitation of burning and compost treatment, use are a variety of
The garbage comprehensive treatment technology of waste disposal method optimum organization, to obtain optimal environmental benefit, social benefit and economic effect
Benefit.
The patent document for disclosing Application No. 200710011116.5 in the prior art is a kind of based on Biological Pretreatment
House refuse carries out the technique of integrated treatment, belongs to environmental technology field, it is characterised in that mainly by the artificial Pre-sorting of rubbish, life
Thing pretreatment, garbage compost and garbage incineration process composition, house refuse are divided into 4 classes, brick and tile after artificial Pre-sorting, by rubbish
Stone component is used to building the road or filling out hole, and recyclable component recycles；Hazardous waste send hazardous waste treatment plant to centrally dispose；It is surplus
After remaining rubbish carries out Biological Pretreatment, it is divided into biodegradable component and combustible component, biodegradable component through mechanical sorting
Land use, combustible component burning disposal are carried out after compost treatment.The present invention is first by carrying out artificial pre- point to house refuse
, there is the drawbacks of efficiency of separation is relatively low in choosing, and the house refuse for not doing any processing is easily intertwined, and undoubtedly enter again
One step improves sorting difficulty, and the technical program carries out burning disposal to combustible component, and easily producing dioxin etc. largely has
Evil gas, if directly discharge can cause air pollution, if handling gas, greatly improves processing cost, to sum up
Described, existing needs improved weak point.
