Abstract

The invention discloses a natural circulation microbial agent for decomposing hydrogen sulfide and a preparation method of the natural circulation microbial agent. The microbial agent is prepared by adding strains into a fermentation liquid base solution for fermentation, wherein the strains include rhodopseudomonas, rhodospirillum, lactobacillus, candida, streptomyces, thiobacillus and xanthomonas, and the total bacteria density in the microbial agent is 6*10<8>-8*10<8> per liter. According to the microbial agent prepared by virtue of the preparation method, hydrogen sulfide can be effectively and rapidly decomposed, the microbial agent can be taken as a microbial deodorant, meanwhile, the growth of bacteria can be inhibited, the production of hydrogen sulfide gas is reduced, and meanwhile, the amount of marsh gas produced by the bacteria can be reduced; and the preparation method is simple, the preparation cost of the microbial agent is low, and the loss of living bacteria is greatlyreduced.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a natural circulation microbial bacterial agent for decomposing hydrogen sulfide and a preparation method thereof. Background technique [0002] Hydrogen sulfide has a strong neurotoxin and has a strong stimulating effect on sticky mold. After the human body absorbs it, it will cause functional changes in the nervous system of heatstroke, tracheal and bronchial sticky mold irritation symptoms, and pathological changes in the cerebral cortex. Hydrogen sulfide is a by-product of the chemical process. The products of certain chemical reactions and the natural decomposition of proteins, as well as the components and impurities of some natural products, often exist in various production processes and in nature. Such as mining and non-ferrous metal smelting, low-temperature coking of coal, sulfur-containing oil extraction, refining, rubber, leather, dyes, sugar and o...
