Description
Technical field
The present invention relates to a kind of sorting of domestic garbage resource, method for innocent treatment, especially a kind of electric power, building materials rows
Industry cooperates with landfill yard recycling, the method for harmless treatment house refuse.
Background technology
Rubbish is that the product rubbish of human civilization is the product of human civilization, and people are while enjoying material progress, often
It is all abandoning various house refuses.As urban modernization, Urbanization Process are accelerated, Living consumption
Raising, Output of Domestic Waste is growing day by day, and ingredient is increasingly sophisticated, harm it is increasingly serious.The life that China cities and towns generate every year
About 300,000,000 tons of rubbish living, and with annual 9% speed increase.Wherein 80% or more without recycling, harmless treatment.The whole nation is gone through
Untreated domestic waste heap is high-volume up to more than 80 hundred million tons over year, more than 500 ten thousand hectares of appropriation of land.There is more than 200 city
Garbage-surrounded city.House refuse has become a big public hazards in current city and market town.
Since the sixties, a large amount of human and material resources have been put into both at home and abroad, financial resources carry out Disposal of Municipal Refuse
Research.Currently, the main treatment technology in home and abroad has three kinds of " landfill method ", " burning method " and " composting method " etc.." landfill method " is me
The main method of state's Disposal of Domestic, due to local financial resources deficiency, " landfill method " although method is simple, operating cost is relatively low,
But the sanitary landfills specification that national requirements is not pressed in most of cities and towns is disposed, and is directly dumped rubbish using some ditch that gives up, pools, landfill yard
Often sewage flows over, stinking smell assaulting one's nostrils, mosquitos and flies causes disaster, and serious environmental pollution is constituted to the air, water body, soil of surrounding.
The masses suffer untold misery around area, cause social unstability.In addition, plastic garbage bag volume accounts in the rubbish of refuse landfill landfill
More than half of garbage bulk, by bull-dozer, stacking pressure, a large amount of plastic foil are landfilled in layer when landfill, it is upper it is century-old all regardless of
Solution, after landfill yard fills up rubbish, native Barren is airtight, waterproof, at it is long-term it is difficult repair it is useless.Some flourishing cities for many years
For recycling treatment municipal refuse, spends huge sums and introduce Domestic garbage bag-breaking, broken, sorting technology and equipment from Europe, the United States.Eventually because not
Be suitble to the national conditions of China's municipal refuse mixed collection, can not be solved in the broken bag of rubbish, broken, assorting room winding, swaging clamp,
The technical barriers such as blocking, end in failure.One side urban refuse pollution is increasingly severe, and improvement is very urgent, another
Aspect recycling, innoxious, minimizing processing domestic waste can not find ripe preposition preconditioning technique equipment.Then, closely
Garbage incinerating power plant is built over year and has become " agitation ", it has been burnt with way one.Garbage as resource health " landfill " few enterprises
It makes inquiries.Though the direct power generation by waste combustion of rubbish is a kind of method of garbage as resource processing, it is not reasonable method：First, investment
Greatly：Garbage disposal ability per ton need to invest ten thousand yuan of 60-100, and the investment payback time is long.Second is that seriously polluted：Because msw water content is high,
Pre fermentation processing in 7-15 days need to be stored, the Leachate site of 10-15% is generated；It burns one ton of rubbish and generates about 5000m3Exhaust gas,
It is the dirt for causing air pm 2.5 to pollute including strong carcinogens such as bioxin, heavy metal flying dusts containing tens of kinds of pollutants
One of dye source；Generate clinker, the ash of rubbish total weight 20-30%.Third, producing cost height：Burn one ton of rubbish producing cost
90-120 members, profit subsidize (70-120 yuan/ton) mainly by local governments at all levels' processing rubbish；Fourth, since rubbish is constituted again
Miscellaneous, unstable quality, it is high that therefore, it is necessary to daily management technical merits, and real time monitoring is difficult, in addition enterprise with maximize profit for
Objective, control pollution are difficult.Fifth, garbage power itself can not form how many benefit, government subsidy is leaned on, there are certain risks, most end form
Not at industry.Sixth, waste incineration and generating electricity pollution is big, periphery common people are difficult to receive, and select factory site difficult, as long as one mix must
It stops production, has many examples that can should demonstrate,prove both at home and abroad.Therefore, the direct power generation by waste combustion of rubbish its " wind " swept at present be it is expedient it
Meter.
