Abstract

The invention discloses Acinetobacter baumannii AL-6 and an application thereof. The strain is preserved in the China General Microbiological Culture Collection Center (CGMCC) in November 8th, 2016, and the preservation number is CGMCC No. 13248. The strain can conduct denitrification through heterotrophic nitrification-aerobic denitrification. Under the aerobic condition, with CH3COONa as a carbon source and NH4+-N as a nitrogen source, removal of 81.9-99.9% of NH4+-N and 59.7-90.8% of TN can be achieved; with NO3--N as a nitrogen source, the removal rate of NO3--N is 50.2%, and the removal rate of TN is 48.2%; with NO2--N as a nitrogen source, the removal rate of NO2--N is 50.3%, and the removal rate of TN is 48.8%. The strain AL-6 has good application prospects in the field of treatment of wastewater containing highly concentrated ammonia-nitrogen or nitrate nitrogen or nitrite nitrogen.

Description

technical field

[0001] The invention belongs to the field of environmental microorganisms, and in particular relates to a strain of Acinetobacter baumannii ( Acinetobacter baumannii ) AL-6, and its application in the treatment of high-concentration ammonia nitrogen, nitrate nitrogen, and nitrite nitrogen wastewater. Background technique

[0002] With the rapid advancement of urbanization, the problems of water resource shortage and pollution have become increasingly acute, among which the problem of ammonia nitrogen pollution is particularly prominent. According to the Bulletin on the State of the Environment in China, the total discharge of ammonia nitrogen in my country reached 2.385 million tons in 2014. The direct discharge of ammonia nitrogen into the water body will not only cause eutrophication and black odor of the water body; it will also increase the difficulty and cost of water treatment, affect domestic water and industrial water supply, and cause direct economi...
