A kind of compound microbial deodorant for processing household garbage and preparation method thereof

Abstract

The invention relates to a composite microbial deodorant for treating household garbage and a preparation method of the deodorant. The composite microbial deodorant is prepared from raw materials as follows: 20-30 parts of composite photosynthetic bacterium powder, 10-20 parts of Bacillus subtilis powder, 20-40 parts of composite aspergillus powder and 30-50 parts of composite yeast powder. According to the composite microbial deodorant, hydrogen sulfide, ammonia as well as strains adapted to the household garbage are screened and degraded in a targeted manner, the composite microbial deodorant comprises beneficial microbes such as Thiocapsa roseopersicina capable of efficiently degrading the hydrogen sulfide, Rhodospirillum rubrum capable of efficiently degrading fatty acid series odors and the ammonia, Aspergillus oryzae rich in enzyme systems such as proteases, cellulose and the like, Bacillus subtilis capable of quickly degrading the ammonia, Rhizopus oryzae rich in lactic acid, Saccharomyces cerevisiae for producing ethyl alcohol, Candida guilliermondii rich in aroma-producing substances and the like, the beneficial microbes grow and breed in the household garbage and have the synergistic effect, the ecological environment of the household garbage is effectively improved, and emissions of the hydrogen sulfide, the ammonia and the fatty acid series odors are greatly decreased.

Description

technical field [0001] The invention relates to a compound microbial deodorant for treating domestic waste and a preparation method thereof, in particular to a compound microbial deodorizer for treating domestic waste collection stations, domestic waste landfills and / or domestic waste disposal sites agent and its preparation method. Background technique [0002] According to statistics, the annual output of domestic waste in my country has reached 200 million tons, and the stockpile over the years has reached 6.6 billion tons, which is close to the level of developed countries, and the landfill disposal volume has reached more than 95% of the total waste. During the process of transshipment, tiling, compaction, disposal and landfill of garbage, a large amount of strong and irritating odor gas will be produced, which will directly or indirectly affect the surrounding environment and human health. As a public nuisance, stench seriously affects people's physical and mental hea...

AI Technical Summary

Problems solved by technology

Generally, compound microbial deodorants also have poor coexistence of various strains, poor strain stability, and poor degradation of hydrogen sulfide and ammonia, which limit the further application of compound microbial deodorants
