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

Abstract

The invention relates to a pollution-free synthetic treatment method for garbage in villages and towns, comprising: after collecting the garbage in the villages and towns, classifying biomass garbage and non-biomass garbage, then classifying the biomass garbage into non-perishable biomass garbage and perishable biomass garbage, crushing the non-perishable biomass garbage and pressing into blocks, further feeding into a pyrolytic gasification device to perform the pyrolytic gasification so as to be combustible biomass gas, and sewage of the perishable biomass garbage entering into an anaerobic fermentation device, being marsh gas after the anaerobic fermentation, slag charges thereof entering into a slag tank, slag liquid entering into a liquid storage tank to be field fertilizer, accessing the biomass gas and the marsh gas into a furnace, and using the high temperature of the hearth to effectively treat dioxin in the biomass gas. The usable material, charcoal, fuel, hot water reclaimed and produced in the treatment procedure can bring benefits for the processors, thereby forming a good recycle of the garbage treatment.

Description

technical field [0001] The invention relates to resource utilization and environmental protection, in particular to a harmless comprehensive treatment method for rural and town garbage. Background technique [0002] At present, with the development of the domestic economy, the appearance of the countryside has undergone tremendous changes. Farmers are living in high-rise buildings, using household appliances, and owning some cars. The countryside has indeed become richer. However, the environment and sanitation there are unsatisfactory. Garbage is piled up indiscriminately, sewage flows sideways, continuously erodes the surface, pollutes small ponds and small rivers, not only affects the health of farmers, but also continuously discharges sewage from small ponds and small rivers downstream, making The water security of downstream cities is under great threat. In recent years, governments at all levels have spent a lot of effort to deal with the ever-emerging "garbage siege"...

AI Technical Summary

Problems solved by technology

At present, there are two methods of garbage disposal in China: one is to "landfill" landfills, and set up landfills around large and medium-sized cities. It is a very precious land resource, and if the landfill is not handled carefully in advance, it is very likely to pollute the groundwater, and it will also leave endless hidden dangers for our future generations

The second is to incinerate "waste" and build waste incineration plants around large and medium-sized cities. However, imported equipment is expensive, and domestic equipment still has technical defects. The incineration plant not only has a huge investment, but also has strict requirements on garbage classification. During the incineration process, "tar" and "dioxin" emissions will be produced. Tar has a huge erosion on the surface, and no grass will grow there. "Dioxin" is very harmful to the human body. Even a fraction of a gram can be fatal

Well done cities above the provincial capital adopt the method of collecting garbage in villages, transiting in counties and towns, and centralizing treatment in cities. The cost of transportation and management is very high, and at the same time, it increases the huge cost of urban garbage disposal in rural areas.
