Abstract

The invention relates to a salt-tolerant aerobic denitrification bacterium rhodococcus erythropolis LH-N13 with a collection number of CGMCC No. 6974. The invention also discloses a microbial agent of rhodococcus erythropolis and an application of the microbial agent in high-salinity nitrogen-containing wastewater. The strain is screened from salt field sludge and has strong tolerance against high salinity; under the condition of the salinity (based on NaCl) less than or equal to 15%, nitrate nitrogen and nitrite nitrogen in the sewage can be removed, the microbial agent prepared from the strain can be directly used for denitrifying high-salinity wastewater, can be used for solving the difficult problem that the biological nitrogen removal total nitrogen is difficult to meet the standard under a high-salinity environment and has good application prospects. The salt-tolerant denitrification bacterium rhodococcus erythropolis LH-N13 or the microbial agent prepared from rhodococcus erythropolis LH-N13 can be used for the biological treatment of the high-salinity nitrogen-containing wastewater produced in food processing, bio-brewing, pesticides and leather.

Description

technical field

[0001] The invention relates to a salt-tolerant aerobic denitrifying Rhodococcus erythrococcus ( Rhodococcus erythropolis ) LH-N13, its microbial agent and its application in the treatment of high-salt nitrogen-containing wastewater. Background technique

[0002] In industries such as seafood processing, salted products processing, chemical industry, petroleum and aquaculture, most of the discharged nitrogen-containing wastewater has the characteristics of high salt. For example, metal refining wastewater contains a large amount of nitrate nitrogen, and seafood processing wastewater generally contains a large amount of protein and ammonia nitrogen. High-salt wastewater generally refers to wastewater with a total salt content of at least 1%. In many industrial practices such as seawater substitution, the salt content is sometimes as high as 15-30%. At present, the production methods and output of high-salt wastewater are increasing. The amount of wastewater ...
