Abstract

The invention provides a Pseudomonas nitroreducens. strain and application thereof. The strain is Pseudomonas nitroreducens. Pf2, and is preserved in China Center for Type Culture Collection, and the preservation number is CCTCC NO: M2021274. The strain can synchronously perform nitrification and denitrification by taking organic carbon as a carbon source under an aerobic condition, and is suitable for removing organic wastewater containing ammonia nitrogen or nitrate, the NH4 < + > -N removal rate can reach 92.7 percent, and the NO3 < - > -N removal rate can reach 100 percent; and the treatment process can be greatly simplified, the treatment efficiency is improved, and the operation and maintenance cost is reduced.

Description

technical field

[0001] The invention belongs to the technical field of environmental protection, and in particular relates to a nitroreductor pseudomonas strain with heterotrophic nitrification and aerobic denitrification function and application thereof. Background technique

[0002] Water nitrogen pollution has become the most serious environmental problem in the world, and biological denitrification is the most economical and effective disposal method in water pollution treatment. Traditional biological nitrogen removal mainly includes nitrification and denitrification. Biological nitrification and denitrification processes are interdependent, but because there are huge differences in the physiology and biochemistry of nitrifying and denitrifying microorganisms, so the dissolved oxygen (Dissolved oxygen, DO), temperature, pH, growth rate, chemical oxygen demand (Chemical oxygen demand) ,COD) and nitrate and nitrite have different tolerance and performance. This makes it...
