Abstract

The invention relates to application of a microbial agent to malodorous gas pollution regulation. Malodorous gas is nitrogen-containing or sulfur-containing inorganic / organic malodorous gas or volatile heterocyclic organic gas, and the microbial agent is formed by comamonas testosteroni LH-N5, achromobacter xylosoxidans subsp. xylosoxidans LH-N25CGMCC No.6972 and Paracoccus aminovorans LH-N40CGMCC No.6971 in any proportion. The microbial agent has a remarkable deodorization effect, can tolerate or degrade organic and toxic pollutants, is particularly suitable for deodorization and purification of nitrogen-containing or sulfur-containing inorganic / organic waste gas, is suitable for regulation of volatile heterocyclic toxic organic malodorous gas, has a simple treatment process and stable effects, is resistant to environmental toxicant impact, and has wide application prospect in malodorous gas pollution control.

Description

technical field [0001] The invention belongs to the field of environmental microorganisms, and in particular relates to the use of a microbial bacterial agent in the treatment of malodorous gas pollution. Background technique [0002] Malodorous gas refers to volatile substances that can cause disgust or unpleasant odors in the human body, and is a kind of sensory (olfactory) pollution that is perceived by acting on the human olfactory organs through the air medium. In recent years, with the development of society, the improvement of people's living standards and the enhancement of people's awareness of environmental protection, people have put forward higher requirements for the quality of the air environment, and the lawsuits related to odor pollution have continued to increase, such as Nanjing, Jiujiang, Beihai and other cities There have been large-scale odor pollution incidents that have seriously affected the living environment of residents, and the treatment of odorou...
