Abstract

The invention relates to denitrification acinetobacters and a use thereof, and belongs to the field of environmental microbiology. The denitrification acinetobacters have a category name of Acinetobacter schindleri LN5, are preserved in the China general microbiological culture collection center of the China microbiological preservation management committee on May 30th, 2012, and has a preservation number of CGMCC No.6165. The denitrification acinetobacters have heterotrophic nitrification-aerobic denitrification functions, have high aureomycin resistance, can be used for simultaneous nitrification and denitrification (SND) treatment on nitrogen-containing sewage and especially on nitrogen and aureomycin-containing sewage, realize removal of a large part of ammonia nitrogen in nitrogen-containing sewage, realize small accumulation amounts of nitrite and nitrate nitrogen, realize nitrification-denitrification and COD removal in the same reactor, and realize environmentally-friendly, low-consumption and high-efficiency treatment on nitrogen-containing sewage.

Description

technical field

[0001] The present invention relates to a denitrification Acinetobacter and its application, in particular to a denitrification Acinetobacter LN5 (Acinetobacter schindleri LN5), the denitrification Acinetobacter LN5 has good tolerance to aureomycin ability, and has the function of heterotrophic nitrification-aerobic denitrification, which can be used for biological denitrification treatment of nitrogen-containing sewage and aureomycin-containing sewage, and belongs to the field of environmental microorganisms. Background technique

[0002] Nitrogen is one of the main factors causing eutrophication of water bodies, and the substandard discharge of nitrogen-containing sewage aggravates the eutrophication of water bodies. Nitrogen removal methods in sewage are divided into physical and chemical denitrification methods and biological denitrification methods. Physicochemical denitrification method is expensive and difficult to popularize and apply. Biological de...
