Abstract

The invention provides a bacterial strain with heterotrophic nitrification and aerobic denitrification functions and application. The bacterial strain is (Achromobacter xylosoxidans) pf1, the bacterial strain is preserved in the China Center for Type Culture Collection, and the preservation number is CCTCC NO: M2021273. The bacterial strain can synchronously perform nitrification and denitrification for nitrogen removal by taking organic carbon as a carbon source under an aerobic condition, and is suitable for removal of organic wastewater containing ammonia nitrogen, nitrate and nitrite. In the ammonia nitrogen wastewater with the initial concentration of 175 mg / L, the total nitrogen removal rate can reach 100%, the accumulation of intermediate products is less, and secondary pollution is avoided; in nitrate or nitrite wastewater with the initial concentration of 100 mg / L, the total nitrogen removal rate can reach 87.1% or 65.1%. After the industrial turtle breeding wastewater is treated, nitrogen and phosphorus in the industrial turtle breeding wastewater can be remarkably removed.

Description

technical field

[0001] The invention belongs to the field of environmental microorganisms, and in particular relates to an Achromobacter strain with heterotrophic nitrification-aerobic denitrification functions and its application in the treatment of ammonia nitrogen, nitrate nitrogen and nitrite nitrogen wastewater. Background technique

[0002] At present, a major problem facing my country's water environment protection is that the concentration of ammonia nitrogen in the water far exceeds the self-purification capacity of the sewage. The national surface water environmental quality in the first half of 2016 shows that 11.3% of my country’s top ten river basins are inferior to Category V, of which COD, ammonia nitrogen and total phosphorus are the main pollution indicators, and the oxygen-consuming pollutant ammonia nitrogen has become a major factor affecting the environmental quality of my country’s surface water bodies. primary indicator. The severe situation of ammonia...
