Process for deodorizing household garbage, increasing methane yield and accelerating garbage degradation

Abstract

The invention relates to a process for deodorizing household garbage, increasing methane yield and accelerating garbage degradation, which comprises the following steps: step 1, mixing a microbial agent and molasses in proportion, culturing and expanding to form expanding liquid; step 2, uniformly mixing the hair expanding liquid and the ultrafiltration water according to a certain volume ratio to prepare a mixed liquid A; uniformly mixing the expansion liquid, ultrafiltration water and glucose according to a certain volume ratio to obtain a mixed liquid B; 3, mixed liquid is sprayed to the surface of the garbage, specifically, the mixed liquid A is sprayed in the morning, and the mixed liquid B is sprayed at night; step 4, welding an HDPE film to form a cover film and an air passage; covering the surface of the garbage with a covering film and an air passage; 5, arranging a landfill gas collecting pipe below the covering film; an air exhaust pipeline assembly is installed on the covering film, and the landfill gas collecting pipe penetrates out of the covering film to be communicated with the air exhaust pipeline assembly to extract landfill gas. The method has the effects of improving the deodorization rate of the household garbage, improving the methane yield and accelerating garbage degradation.

Description

technical field [0001] The present application relates to the technical field of garbage disposal, in particular to a process for deodorizing domestic garbage, increasing methane production, and accelerating garbage degradation. Background technique [0002] With the acceleration of my country's urbanization process and the increase of urban population, garbage as a waste generated in daily life and production process has also increased sharply. The odorous substances produced by the decomposing and decomposing of the garbage piled in the garbage transfer station and the garbage landfill not only have a serious impact on the ambient air quality, but also endanger the health of the residents and cause respiratory diseases and other diseases. [0003] At present, the technologies for treating domestic waste mainly include sanitary landfill, incineration and composting. Among them, sanitary landfill is the most widely used technology for urban domestic waste treatment, and the ...

AI Technical Summary

Problems solved by technology

[0003] At present, the technologies for domestic waste treatment mainly include sanitary landfill, incineration and composting, etc. Among them, sanitary landfill is the most widely used technology for urban domestic waste treatment, while the existing The landfills are all simple landfills or anti-seepage landfills, most of which are open-air outdoor sites. After the organic waste is accumulated and fermented, it will produce a strong pungent odor gas, which is very volatile and escapes into the atmosphere. , causing air pollution; moreover, there is a large amount of garbage accumulated in the garbage dump, the degradation rate of garbage is low, and the content of methane in the generated landfill gas is low, which is difficult to meet the recycling of resources

[0004] In view of the above related problems, the inventor believes that the existing waste treatment process has the defects of low treatment efficiency and serious odor pollution
