Problems solved by technology

[0003] At present, the methods of odor removal can be divided into two aspects: chemical deodorization and biological deodorization. The principle of chemical deodorization is to oxidize and degrade the odor components through exogenous strong oxidizing substances, so as to eliminate the odor. Although it is highly targeted, Quick effect, but its application range is small. When encountering complex odorous gas components, the deodorization effect will be invalid, and the residual chemical substances after using chemical deodorants often cause secondary pollution

Abstract

The invention provides a microbial preparation for purifying air. By utilizing the synergic effects of streptococcus thermophilus, pseudomonas putida, rhodopseudomonas palustris, bacillus pumilus and enterococcus faecium, the microbial preparation is capable of effectively reducing concentration of stink comprising ammonia gas, hydrogen sulfide and the like in the air at toilets, culturing farms, dumps and the like, and inhibiting stink-producing elements, so that air quality and human living environment can be substantially improved. A production method provided by the invention is simple, is applicable to majority of conventional fermentation technologies and equipment, and is suitable for large-scale popularization and application.

Description

technical field [0001] The invention relates to the technical field of microbial application, in particular to a microbial preparation for purifying air and its application. Background technique [0002] Odor pollution is one of the seven major environmental hazards recognized in the world. Common odor pollutants include ammonia, trimethylamine, hydrogen sulfide, methyl mercaptan, dimethyl disulfide, carbon disulfide, and styrene, which mainly come from industrial and agricultural production departments and people's lives, such as those produced in agricultural and animal husbandry production and processing The smell of manure, fish, corruption, rotten fruit, wild vegetables, etc. Sulfides, hydrocarbons, benzene, phenols and ammonia produced in the petrochemical production process, as well as tar, asphalt vapor, ammonia and various organic solvents, as well as the stench of urban public facilities. High concentrations of odorous pollutants are directly harmful to human hea...
