Description

Pollution-free synthetic treatment method for garbage in village and town

Technical field

The present invention relates to the utilization of resources and environmental protection, particularly pollution-free synthetic treatment method for garbage in village and town.

Background technology

Current, along with the development of domestic economy, huge variation is taking place in the looks in rural area, and the peasant has lived in building, and household electrical appliance have been used, and the automobile that has has also had, and the rural area has richened really.But environment, the health of there are unsatisfactory, and rubbish huddles and leaves about, the sewage crossing current constantly corrodes the face of land, has polluted pulk, river, not only influence peasant health, and the constantly discharging downstream again of pulk river sewage, make downstream urban water safety be subjected to very big threat.In recent years, governments at all levels have spent very big strength, tackle " garbage-surrounded city " situation of continuous appearance, have also spent very big financial resources and have solved the rubbish processing to be harmless problem.At present, the method of domestic common garbage disposal has two: one, with " garbage loading embeading ", periphery is set up landfill yard in big and medium-sized cities, landfill spends substantial contribution that garbage power is used, still after the several years again, the most valuable land resource of this method waste, and landfill yard has in advance slightly to be handled accidentally, and just polluted underground water very likely also will stay infinite hidden danger to our descendants.The 2nd, with " waste incineration ", periphery is set up garbage burning factory in big and medium-sized cities, but import equipment costliness, still there is technological deficiency in home equipment, incineration plant is not only invested huge, and to the classificating requirement strictness of rubbish, bad if classify, in burning process, will produce the discharging of " tar " and " dioxin " so, tar is huge to terrestrial erosion, and not even a blade of grass grows in the flow path there, and " dioxin " is extremely harmful to human body, that I guess sucks ten thousand/even 1/100000000th grams, also can produce mortal injury to the people.Therefore, the there has burns the field, and peripheral resident there all can rise vigorously to oppose, constantly cause burst, colony's incident.

Rubbish as for rural area, town still is in the state of letting drift.Do the above city of reasonable provincial capital, then take the village to collect rubbish, county and town's transfer, the city concentrates the method for handling, its transportation, management cost are very big, have increased the city simultaneously again and have handled the significant cost of rural garbage.Owing to can not fully utilize rubbish, its financial burden then can for good and all be born down.

Summary of the invention

The objective of the invention is, solve the above-mentioned deficiency that " garbage loading embeading ", " waste incineration " two kinds of methods are brought effectively, adopt integrated conduct method to solve the innocuity treatment problem of villages and towns in rural areas rubbish, rubbish is turned waste into wealth, and make collection, processing, the comprehensive utilization of rubbish become benign cycle economy.

For achieving the above object, the technical scheme that the present invention takes is, pollution-free synthetic treatment method for garbage in village and town, be on the spot rubbish to be carried out Harmless and Comprehensive Disposal in rural area, the source town that rubbish produces, carry out the classification of living beings and abiotic matter rubbish after the refuse collection in advance, after abiotic matter rubbish carries out sifting sort, as the recyclable goods and materials that utilize, biomass garbage is categorized as not perishable living beings and perishable biomass garbage, it is characterized in that: not perishable biomass garbage is through pulverizing, and after pressure injection becomes bulk, enter pyrolysis gasifying device again and carry out pyrolytic gasification, water-oil separating becomes flammable biomass gas through air water, slag that produces behind the pyrolytic gasification or charcoal, and the dirt ash that produces after utilizing again can be used as organic fertilizer; Its garbage leachate of perishable living beings enters anaerobic ferment devices, becomes biogas after the dehydration desulfurization, and its slag charge enters the slag charge pond, and slag liquid enters liquid storage tank, becomes field fertilizer; Biomass gas and biogas insert a boiler, utilize burner hearth high temperature that " dioxin " in the biomass gas is effectively addressed.

The present invention has three big advantages: the one, and garbage disposal obtains the in advance classification of living beings and abiotic matter rubbish, and abiotic matter rubbish is recycled earlier, has reduced the garbage disposal total amount; The 2nd, adopt pyrolysis gasifying device, make not perishable biomass garbage form fuel gas and charcoal thereof; Adopt marsh gas device, make perishable biomass garbage form biogas and organic fertilizer thereof, saved the required energy of disposal of refuse to greatest extent, biomass gas or form the above high temperature of 900 degree Celsius with biogas mixed combustion effectively solves " dioxin " noxious gas emission.As if burn like that, indiscriminately, perishable and not perishable rubbish mixed burning not only needs the very big energy in addition, and is difficult to solve " secondary pollution " problem of being brought; The 3rd, garbage disposal is placed on the source that rubbish produces, rubbish transportation, administrative expenses have not only been saved, and reclaimed fully and utilized by garbage disposal, resource, goods and materials, the charcoal of generation, combustion gas, hot water that its processing procedure reclaims are the processor and bring benefit, thereby the oneself's benign cycle, once investment, the once and for all that have realized garbage disposal solve the purpose of rural area town's rubbish processing to be harmless.
