Deodorization method for town refuse biology re-fermentation

Abstract

The re-ferment deodorization of urban garbage is the adding of mixed deodorization bacteria into the cleaned garbage, namely Bullera sinensis Li CGMCC 2.1614, Rhodotorula minuta CGMCC 2.277, Candida tropicalis CGMCC 2.1387 and myces kurssanovii CGMCC 4.509. It can use all kinds of bacteria to remove odors released from fermented biology.

Description

Technical field: [0001] The invention belongs to the technical field of urban garbage deodorization methods, in particular to the technical field of municipal garbage biological deodorization methods. Background technique: [0002] With the development of the economy, more and more urban garbage, the biological recycling of garbage has become a new trend, compared with the current landfill method and garbage incineration method, the biological recycling method of garbage occupies less land and does not pollute the environment Features. Waste biological recycling mainly includes rough sorting process, bag breaking process, biological pretreatment process, primary sorting process, re-fermentation process, secondary sorting process, drying process, selection process, and organic fertilizer process. Raw garbage first undergoes a rough sorting process, separating the bamboo and wood packaging boxes and rubber tires, and breaking the large pieces; the rough sorted garbage is brok...

AI Technical Summary

Problems solved by technology

Raw garbage first undergoes a rough sorting process, separating the bamboo and wood packaging boxes and rubber tires, and breaking the large pieces; the rough sorted garbage is broken into bags, and the broken bags are subjected to biological pretreatment. Treatment, the infiltration water produced by biological pretreatment enters the sewage treatment system, and the waste gas generated enters the waste gas treatment system; the garbage that has undergone biological pretreatment is sorted once, using wind force, gravity, magnetic force, bounce, shape, speed, etc. The technology sorts out bamboo and wood, waste batteries, plastics, glass, lighters, metals, fabrics, etc. for recycling, and uses inorganic materials such as bricks, tiles and stones for the manufacture of new building materials; the garbage that has been sorted for the first time is recycled. Re-fermentation, the re-fermented garbage is sorted for the second time, and the combustibles, sand and stones, fine glass, etc. in the garbage are sorted out, and the second-sorted garbage is dried, selected, and fertilized. During the pretreatment process and the re-fermentation process, there are often foul odors. Chinese patent 03118139 provides a deodorant, a deodorizing accelerator and a method for deodorizing the composting of garbage. The deodorant and deodorizing accelerator used in it are It is the same in the biological pretreatment and re-fermentation process, because the biological pre-treatment process and the re-fermentation process are different fermentation processes, so the deodorant and accelerator are not very targeted
