Embodiment

[0037] The odor treatment of domestic garbage in a garbage treatment plant includes the following steps:

[0038] a. Every day, 133 15-ton garbage trucks dump 2000 tons of domestic garbage into the garbage pit in the garbage unloading hall. The 5-ton garbage grab machine picks up the garbage, moves it to the top of the garbage collection pit, and then grabs the garbage. Loosen slowly to make the garbage fall loose. The spray device located at the corner of the garbage collection pit sprays the enzyme bacteria liquid to the grab and the fallen garbage so that the enzyme bacteria liquid and the garbage are fully in contact with the garbage at a temperature of 10 ~ 30 ℃, humidity The retting reaction is carried out under the conditions of 40 to 80%. The garbage unloading hall accepts 2000 tons of garbage every day, and multiple cranes and grabs need to be installed in conjunction with a biological enzyme spray system. Among them, the enzyme bacteria liquid is prepared by mixing lac...

Abstract

The invention discloses a treatment method for domestic garbage odor, which belongs to the technical field of domestic garbage treatment. The processing method comprises the following steps: a. Start the garbage grab machine to pick up the garbage and slowly loosen it, so that the garbage falls loosely, and sprays the enzyme and bacteria liquid evenly on the garbage while the garbage is falling; b. Cover the garbage pile with a plastic film Carry out anaerobic fermentation treatment; c, open the plastic film and repeat steps a and b until the garbage odor is eliminated; d, screen the garbage that has eliminated the odor; e, recycle and reuse the inorganic garbage; Garbage that cannot be recycled shall be treated for heavy metal removal or reduction after heavy metal detection. The treatment method of the invention can efficiently, stably and quickly treat the malodorous gas in the domestic waste treatment plant, has good treatment effect, and low investment and operation costs.

Description

Technical field [0001] The invention relates to the technical field of domestic garbage treatment, in particular to a method for treating the odor of domestic garbage. Background technique [0002] In the process of comprehensive sorting, composting and landfill treatment of municipal solid waste, malodorous gases whose main components are hydrogen sulfide, mercaptans, ammonia and volatile organic compounds are generated. The odorous gas produced by the municipal solid waste plant has a low threshold concentration and is highly corrosive to equipment and pipelines. It can also interfere with normal industrial production and the daily life of surrounding residents, and cause serious human health and ecological environmental hazards. [0003] Conventional treatment technologies for malodorous gas in municipal solid waste treatment plants mainly include absorption, adsorption, catalysis, incineration and plasma technologies. In recent years, biological treatment technology, especiall...
