Embodiment 1

[0098] Using domestic waste from a certain city as raw material, the composition is shown in Table 1:

[0099] Table 1 Household garbage composition (wt%)

[0100]

[0101] A. Garbage pretreatment: According to the characteristics of mixed garbage, anaerobic fermentation and dry distillation pyrolysis raw materials are obtained through sorting, screening, crushing, molding and other means;

[0102] The pretreatment includes one or more of the following:

[0103] (1) Domestic waste storage: The incoming waste is poured into the waste pit through the unloading platform, and stays in the pit for 4 days to ensure that it is fully dehydrated and mixed. After percolation, the moisture content of the waste is less than 25%. The separated sewage is collected and sent to the anaerobic fermentation unit for anaerobic fermentation.

[0104] (2) Sorting and crushing: Use a bag breaking machine to break the bags of dehydrated garbage and then sort the garbage into kitchen waste, combu...

Abstract

The invention provides a comprehensive processing method and a processing system of household garbage reutilization. The processing method comprises the steps of sorting and crushing household garbage, so as to obtain kitchen garbage and combustible garbage; performing anaerobic fermentation on the kitchen garbage, so as to obtain methane and residues; performing dry distillation pyrolysis on the combustible garbage, so as to obtain smoke, pyrolytic oil gas and residual solids. By adopting the comprehensive processing method of the household garbage reutilization, the household garbage is divided into the kitchen garbage and the combustible garbage which are specifically processed respectively, so that the effects of innocent treatment of the garbage, no secondary pollution, no dioxin, good reduction, high reutilization level and good economic benefits of products are fully achieved.

Description

technical field [0001] The invention belongs to the field of solid waste treatment, in particular, the invention relates to a comprehensive treatment method and a treatment system for domestic waste resources. Background technique [0002] From a global perspective, with the sustained and rapid economic growth, people's living standards are improving rapidly, and the urbanization process is accelerating, but at the same time, environmental problems are becoming more and more serious, especially the disposal of garbage. How to solve the problem of urban solid waste and restore a healthy and clean living environment for human beings has attracted great attention from all over the world. In 2010, my country's domestic garbage output was 158 million tons, and the accumulated garbage piled up around the city reached 7 billion tons, covering an area of ​​more than 800,000 mu. Almost two-thirds of the 661 cities were surrounded by garbage, which seriously affected the environment. ...
