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 g

Embodiment 1

[0020] Raw garbage first undergoes a rough sorting process, separating the bamboo and wood packaging boxes and rubber tires, and breaking the large pieces;

[0021] The coarsely sorted garbage is broken into bags, and the broken bags are mixed and weighed. During the mixing process, mixed bacteria are added. After the bacteria are expanded and cultivated, they are mixed according to the following volume ratio: Alcalibacter xylosoxidans Alcaligenes xylosoxidans subsp CGMCC 1.768: Bacillus amyloliquefaciens CGMCC 1.1177: Deinococcus radiodurans CGMCC 1.633: Debaryomyces hansenii CGMCC 2.183l: Issatchenkia scutulata CGMCC 2.1592, Aleuisma keratinophilum CGMCC 3.3544: Nocardia brasiliensis CGMCC 4.1128=10:5:10:1:5:10. (Contains 2×10 per milliliter of liquid 7 active cells or more).

[0022] Dilute the mixed strains according to the volume ratio of 1:50, add the diluted mixed strains according to 0.5% (V / W) of the weight of the garbage, ventilate and supply oxygen for fermentatio...

Embodiment 2

[0029] Raw garbage first undergoes a rough sorting process, separating the bamboo and wood packaging boxes and rubber tires, and breaking the large pieces;

[0030] The coarsely sorted garbage is broken into bags, and the broken bags are mixed and weighed. During the mixing process, mixed bacteria are added. After the bacteria are expanded and cultivated, they are mixed according to the following volume ratio: Alcalibacter xylosoxidans Alcaligenes xylosoxidans subsp CGMCC 1.768: Bacillus amyloliquefaciens CGMCC 1.1177: Deinococcus radiodurans CGMCC 1.633: Debaryomyces hansenii CGMCC 2.1831: Issatchenkia scutulata CGMCC 2.1592, Aleuisma keratinophilum CGMCC 3.3544: Nocardia brasiliensis CGMCC 4.1128=12:7:15:15:10:15. (Contains 2×10 per milliliter of liquid 7 active cells or more).

[0031] Dilute the mixed strains according to the volume ratio of 1:75, add the diluted mixed strains according to 2.5% (V / W) of the weight of the garbage, ventilate and supply oxygen for fermentat...

Embodiment 3

[0038] Raw garbage first undergoes a rough sorting process, separating the bamboo and wood packaging boxes and rubber tires, and breaking the large pieces;

[0039] The coarsely sorted garbage is broken into bags, and the broken bags are mixed and weighed. During the mixing process, mixed bacteria are added. After the bacteria are expanded and cultivated, they are mixed according to the following volume ratio: Alcalibacter xylosoxidans Alcaligenes xylosoxidans subsp CGMCC 1.768: Bacillus amyloliquefaciens CGMCC 1.1177: Deinococcus radiodurans CGMCC 1.633: Debaryomyces hansenii CGMCC 2.1831: Issatchenkia scutulata CGMCC 2.1592, Aleuisma keratinophilum CGMCC 3.3544: Nocardia brasiliensis CGMCC 4.1128=15:10:20:30:15:20. (Contains 2×10 per milliliter of liquid 7 active cells or more).

[0040] Dilute the mixed bacteria according to the volume ratio of 1:100, add the diluted mixed bacteria according to 5% (V / W) of the weight of the garbage, ventilate and supply oxygen for ferment...

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...
