Problems solved by technology

The landfill method not only occupies a large amount of land resources, but also causes serious secondary pollution to the land and groundwater; due to the poor classification effect of domestic waste, the calorific value of the material used for incineration for power generation is too low, the power generation efficiency is low, and the dioxin produced by incineration Serious air pollution poses a threat to people's lives and health; diversified treatment is to sort domestic waste and then process various items, but the existing sorting methods are not thorough in the classification of waste, and its resource utilization The rate is not high, still needs further improvement

Embodiment 1

[0038] Such as figure 1 As shown, the domestic waste sorting method provided by the embodiment of the present invention includes the following steps:

[0039] S101: Dehydrating domestic waste to obtain solid waste and leachate.

[0040] The moisture content of domestic waste is generally 45%-70%. In seasons with more rain, the water content is higher. This embodiment provides a method for sorting domestic waste. First, the domestic waste is dehydrated to reduce the treatment of solid waste in subsequent processes. Burden, the leachate after dehydration treatment can be used to make organic fertilizer in the subsequent process, without entering the sewage treatment plant for sewage treatment. The dehydration treatment step may be to place the household garbage in the material bin and let it stand for 3-5 days for dehydration; or directly use a dehydrator to dehydrate the household garbage. Preferably, after dehydration treatment, the water content of the obtained solid waste ...

Abstract

The invention relates to the field of garbage disposal, in particular to a method for sorting household garbage. The method classifies household garbage in detail by adopting the following steps: dehydration treatment, bag breaking, screening, magnetic separation, winnowing, multistage bouncing sorting and picking treatment. The final sorting efficiency of a variety of materials achieves more than 85 percent, the sorting effect is good, the disposal capacity is large, and manpower is saved. After sorting, according to the properties of materials, the classified household garbage is respectively recycled to be reused, deeply reprocessed or harmlessly treated. Thus, the household garbage is largely and quickly disposed, the value-maximized resource recovery of household garbage is realized. The method has great economic value and environmental benefits.

Description

【Technical field】 [0001] The invention relates to the field of garbage treatment, in particular to a method for sorting domestic garbage. 【Background technique】 [0002] With the development of the economy and the improvement of people's living standards, the output of domestic waste is also increasing. At present, domestic mainstream domestic waste disposal methods are landfill, incineration power generation and diversified treatment. The landfill method not only occupies a large amount of land resources, but also causes serious secondary pollution to the land and groundwater; due to the poor classification effect of domestic waste, the calorific value of the material used for incineration for power generation is too low, the power generation efficiency is low, and the dioxin produced by incineration Serious air pollution poses a threat to people's life and health; diversified treatment is to sort domestic waste and then process various items, but the existing sorting meth...
