Penicillium strain and application in treatment of sewage and odor pollution thereof

Abstract

The invention belongs to the field of microbiology, in particular to a penicillium strain which can efficiently degrade wastewater and ammonia nitrogen in odor, and the application in treatment of sewage and odor pollution thereof. Penicillium, also Penicillium purpurogenum by classification, has been preserved in the China General Microbiological Culture Collection Center (CGMCC), CGMCC No. 8036. The bacterial strain has the advantages of efficiently degrading wastewater and ammonia nitrogen in odor, and efficiently treating sewage and odor pollution.

Description

technical field [0001] The invention belongs to the field of microorganisms, and in particular relates to a Penicillium strain that efficiently degrades ammoniacal nitrogen in sewage and odor and its application in treating sewage and odor pollution. Background technique [0002] With the rapid development of social economy and the continuous acceleration of urbanization, the problem of indoor and outdoor environmental pollution has become increasingly prominent, especially the increasingly serious water pollution and air pollution have become the primary factors that bother and threaten human health and daily life. Whether it is water pollution or air pollution, the odor pollution caused by pollutants, that is, stench, not only stimulates human olfactory organs and causes emotional damage such as unpleasantness, but also endangers and damages the biological environment and human health. [0003] Ammonia nitrogen is the nitrogen source obtained by microbial decomposition of ...

Problems solved by technology

However, physical methods and chemical methods often have the problems of expensive equipment, high operating costs, and secondary pollution. Therefore, foreign scholars have devoted themselves to the development of microbial deodorization methods since the 1950s.
