Full-closed recycling 'zero' discharge treatment method for urban and rural domestic garbage

Abstract

The invention discloses a full-closed recycling 'zero' discharge treatment method for urban and rural domestic garbage. The method can be used for treating, fermenting, sorting and burning the garbage generated at each place at any time, so that 'zero' discharge of the garbage is achieved. The method comprises the following steps of: pouring the garbage collected by a garbage collecting vehicle into a mobile garbage pretreatment device, and performing crushing pretreatment; pushing the pretreated garbage into an automatic power modular anaerobic fermentation device, performing anaerobic, aerobic, hot air and microwave drying treatment, and feeding the dried garbage into a travelling wheel type garbage residue negative pressure reclaiming system; and sorting the garbage in a garbage sorting system, feeding the available garbage into a garbage compression device, compressing the garbage to obtain compressed garbage serving as an organic fertilizer, crushing unavailable garbage, feeding the crushed unavailable garbage into a hot air encircling incinerator, and discharging the incinerated residue out of an outlet, wherein the residue is returned to a field or used as a building material. Because reducing and recycling 'zero' discharge of all the garbage is achieved, area pollution of garbage leachate to the land and the water resource can be reduced, and huge social benefit is brought.

Description

technical field [0001] The invention relates to a garbage treatment method, in particular to a "zero" discharge treatment method for fully enclosed resource utilization of urban and rural household garbage. Background technique [0002] The problem of domestic waste in urban and rural areas can be called the "big problem" in environmental improvement. It is a national problem no matter from collection, management to final disposal. [0003] The final disposal of urban and rural domestic waste is a global issue. Especially in our country, the traditional incineration and landfill methods are adopted, which are more primitive, which not only cause secondary pollution problems such as landfill leachate, landfill gas, flying dust and floating objects, but also cause a lot of waste of resources. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a "zero" discharge treatment method for urban and rural domestic garbage fu...
