Household garbage decaying treatment method

Abstract

A household garbage decaying treatment method comprises the following steps that screening is conducted, raw garbage is stacked and subjected to water removal, and products capable of being recycled are preliminarily screened out; the garbage is conveyed into a pulverizer to be subjected to pulverizing treatment; sieving is conducted, the pulverized garbage is placed in a rotary screen to be subjected to segmented sieving and is divided into humus, inertia garbage and high-heating-value garbage; pretreatment is conducted, the inertia garbage is buried and treated on the spot, the high-heating-value garbage is stored after being subjected to compression treatment, then, centralized treatment is conducted, humus aerobic bacterium fermentation is conducted, and continuous gas supply is conducted; fine pulverizing is conducted, continuous pulverizing and secondary fermentation are conducted, thorough decomposing is conducted till the water content is lower than 35%, and nutrient soil is obtained. According to the household garbage decaying treatment method, technology steps are scientific and reasonable, and the household garbage can be turned into wealth from waste and is further produced and prepared into the pollution-free nutrient soil full of the market value and the usage value; and meanwhile, the town garbage treatment burden and the outward transportation amount are reduced. The garbage treatment outward transportation cost and treatment cost are reduced, environment pollution is reduced, and waste is turned into wealth.
