Application of microbial agent to malodorous gas pollution regulation

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.
