Problems solved by technology

[0003] At present, landfill and incineration are the main domestic waste disposal methods, but they have many disadvantages. For example, landfilling a large amount of waste not only occupies a large amount of land resources, but also causes water pollution in nearby areas.
Although the incineration treatment method can recover energy and solve the problems of burying land occupation and aggravating landmark pollution, incineration technology will still bring about air pollution problems

Embodiment Construction

[0014] As shown in the figure, a comprehensive treatment method for domestic waste of the present invention includes sorting and recycling 1, decomposition and treatment 2, and landfill treatment 3; the sorting and recycling 1 is to carry out preliminary classification of garbage and divide it into categories that can be directly recycled There are two types of reusable garbage and garbage that cannot be directly recycled and reused. The decomposition treatment 2 is to decompose the garbage that cannot be directly recycled, and the landfill treatment 3 is to decompose the waste residue after the treatment or the waste that cannot be decomposed. Garbage goes to landfill.

[0015] The sorting and recycling described therein is to carry out preliminary classification of the garbage, and divide it into two kinds of garbage that can be directly recycled and reused and garbage that cannot be directly recycled and reused. The directly recyclable garbage is sterilized and continues to ...

Abstract

The invention discloses a comprehensive treatment method for household garbage. The method comprises the following steps: separation and recovery; decomposition; landfill treatment. The step of separation and recovery comprises primarily classifying garbage into directly recycled garbage and indirectly recycled garbage. The step of decomposition comprises decomposing the indirectly recycled garbage. The step of landfill treatment comprises landfilling decomposed waste residue or garbage which cannot be decomposed. On a basis of overcoming defects of a single treatment method by using a comprehensive treatment technology of household garbage, the household garbage is treated by way of combining separation and recovery, composting, pyrolyzation, landfilling and the like, so that secondary environmental pollution and resource waste due to inappropriate treatment are avoided and reduced. Meanwhile, the purpose of adequately utilizing resources is realized.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment, in particular to a comprehensive treatment method for household garbage. Background technique [0002] In recent years, with the improvement of people's material life quality, the amount of domestic waste has also increased. By 2000, the total annual waste removal and transportation in the country has exceeded 140 million tons, and it has increased by 8%. Over the years, the total amount of disorderly piled garbage in the country has reached 6 billion tons, occupying 500 million square meters of land, seriously polluting the atmosphere and groundwater resources, and even causing gas explosion accidents. [0003] At present, landfill and incineration are the main domestic waste disposal methods, but they have many disadvantages. For example, landfilling a large amount of waste not only occupies a large amount of land resources, but also causes water pollution in nearby areas. Although t...
