A system for recycling domestic waste

Abstract

The invention relates to the technical field of garbage treatment, in particular to a system for recycling and utilizing domestic garbage. The system includes in turn: garbage crushing system, garbage screening system, garbage dehydration system and garbage product forming system; garbage crushing system: used to crush household garbage into fine particles; garbage screening system: through screening, household garbage is divided into multiple Each part includes: the part with higher density of metal and non-metallic materials, the part with less density containing more organic matter, the part with smaller particles or not suitable for separation from water; the garbage dehydration system: the part with less density containing more Extrusion and dehydration of the part with more organic matter; garbage product molding system; plasticizing and molding the dehydrated part of the garbage. The system fully classifies domestic waste, plasticizes and molds the part containing more organic matter, and prepares it into a molded product, which is mainly used as a filler to fill various load-bearing bases, fixed piers, etc. inside.

Description

Technical field[0001]The present invention relates to the field of garbage disposal, and specific relates to a domestic garbage recovery and utilization treatment system.Background technique[0002]With the rapid economic development of my country's social economy, the rapid improvement of people's living standards, the garbage waste generated in the process of urban production and life has increased rapidly, and the local waste occupies land, pollutes the environment and people's health. The impact is also more obvious. Specifically, domestic waste has caused huge harm: organic matter rot, compound decomposition, exudation of ammonia, hydrogen sulfide, odor, contaminated atmosphere; viruses, flora, eggs, etc., breeding, spread; pollutants Accompanied by sewage into the formation, flowing into the river, polluted land and groundwater; metal and its compound analyzes or ionization, pollute water and land.[0003]The large amount of urban domestic garbage increases, making garbage treatme...

Problems solved by technology

[0007] Third, make compost: it may cause the transfer and diffusion of pollutants, especially heavy metal pollutants, and directly pollute farmland and planting plants

[0008] Fourth, incineration: a large amount of harmful gas, dioxin and furnace ash will be produced. The furnace ash contains dioxin and heavy metals, which is very harmful and difficult to handle

[0009] Due to the lack of effective treatment technologies and methods, the contradiction between domestic waste and the living environment has become increasingly prominent, and even long-distance transportation has been bred, dumped into rural areas, rivers, lakes, and seas, and the criminal behavior of transferring pirated waste is severely investigated by the government. , still difficult to eliminate
