Abstract

The invention discloses a method for recycling and comprehensively treating household garbage of urban residents through full resource recovery. The method comprises a garbage classification and collection process, a garbage sorting process and a harmless recycling treatment process. Garbage in each garbage transfer station is conveyed into a garbage unloading area in a vehicle transportation mode, garbage cans of the same type of garbage are classified and sorted through a machine recognition system, the garbage is divided into other garbage, kitchen garbage, recyclable garbage and harmful garbage, the other garbage is used for power generation and landfill, the kitchen garbage is used for composting after being degraded, the recyclable garbage is subjected to magnetic separation, winnowing and photoelectric separation recovery treatment, and the harmful garbage serves as hazardous waste and is treated in a centralized mode. The urban household garbage is intelligently classified according to different garbage categories, and is recycled according to the characteristics of different garbage, so that recycling, harmlessness, reduction, industrialization and profit maximization of the household garbage are achieved.

Description

technical field [0001] The invention belongs to the technical field of garbage sorting and processing, and in particular relates to a method for comprehensively treating and reusing domestic garbage of urban residents. Background technique [0002] In order to realize the purpose of harmless, reduction and recycling of municipal solid waste, the treatment methods of municipal solid waste are being studied at home and abroad.
