Problems solved by technology

[0002] The existing domestic waste treatment methods generally can only realize the recycling of part of the waste, such as only processing and recycling metals, paper, etc., and the more common method is to screen the waste and then classify the small-sized waste However, the selected garbage with a large specific surface area is usually composted or incinerated. This treatment method greatly reduces the recycling rate of garbage resources. At the same time, most of the garbage with a large specific surface area is Artificially synthesized plastics, fibers, rubber and other substances, if these substances are composted, they are not easy to degrade, and are likely to cause pollution and damage to groundwater resources and soil; if they are incinerated, the toxic gases produced will pollute the air and cause the greenhouse effect

Abstract

A process for treating the life garbage includes such steps as delivering the bagged garbage to bag breaker, breaking the bags, classifying to obtain class-A garbage and class-B garbage, wind separating of class-A garbage to obtain heavy garbage A and light garbage A, the magnetic separating, aluminium separating and heavy metal separating of class-B garbage for collecting different metals and garbage B, biochemical fermenting of garbage B1 to obtain fertilizer, separating metals from heavy garbage A, breaking and collecting non-metal garbage, and cracking and degradating the light garbage A to collect gas, liquid and solid.

Description

technical field [0001] The invention relates to a method for converting solid waste into useful things, in particular to a domestic waste treatment method Background technique [0002] The existing domestic waste treatment methods generally can only realize the recycling of part of the waste, such as only processing and recycling metals, paper, etc., and the more common method is to screen the waste and then classify the small-sized waste However, the selected garbage with a large specific surface area is usually composted or incinerated. This treatment method greatly reduces the recycling rate of garbage resources. At the same time, most of the garbage with a large specific surface area is Synthetic plastics, fibers, rubber and other substances, if these substances are composted, they are not easy to degrade, and are likely to cause pollution and damage to groundwater resources and soil; if they are incinerated, the toxic gases produced will pollute the air and cause the gr...
