Household garbage resource utilization comprehensive treatment process

Abstract

The invention relates to a household garbage resource utilization comprehensive treatment process. According to the household garbage resource utilization comprehensive treatment process, household garbage is sequentially crushed and screened, and the household garbage is screened into large substances and small substances; then heavy objects and light objects are sorted from the large substancesthrough a specific gravity winnowing machine; then a fermenting agent is added into the small substances for rapid fermentation, and aerobic fermentation is carried out on biological organic matters in the light substances; humic soil is screened out from the fermented light substances, the remaining light substances are dried, and then rubbing and dry cleaning are carried out; magnetic vortex separation is carried out on the materials subjected to friction and dry cleaning, and an iron, nonferrous metal mixtures and plastic film substances are sorted out; and finally, plasticization polymerization is carried out on the plastic film substances, then crushing and grinding are carried out, and finally extrusion molding is carried out to obtain a plastic product. According to the household garbage resource utilization comprehensive treatment process disclosed by the embodiment of the invention, the plastic film substances in the household garbage are separated, so that the plastic substances are prevented from being treated into pollutants in other sorting treatment processes.

Description

technical field

[0001] The invention relates to the technical field of domestic waste sorting, in particular to a comprehensive treatment process for resource utilization of domestic waste. Background technique

[0002] Most of the garbage in household garbage can be recycled and reused, but various kinds of household garbage are mixed together, making recycling difficult. At present, the commonly used method is to carry out simple screening and then classify, which is difficult to complete sorting, and it is impossible to recycle domestic waste to the greatest extent.

[0003] In related technologies, domestic garbage is usually burned, and a large amount of pollution and harmful substances will be generated during burning. Especially some plastic substances and other organic substances cause pollution and waste of resources. Contents of the invention

[0004] In order to solve the above technical problems, an embodiment of the present invention provides a comprehensive...
