Abstract

The invention relates to a composition for promoting denitrification of anammox bacteria and its application. The composition includes glycolipid, propionate, humic acid or / and humate, wherein the glycolipid is trehalolipid, At least one of sophorolipids, rhamnolipids, etc., preferably trehalose esters. The composition has a simple formula and is easy to prepare. When used in the anammox process, it can improve the denitrification activity of the anammox bacteria and promote the smooth progress of the denitrification process.

Description

Technical field [0001] The present invention belongs to the field of biotechnology, and more particularly to compositions which can promote nitrogen nitrogen in anaerobic ammonia and their applications. Background technique [0002] With the improvement of social and economic development and people's living standards, the content of ammonia nitrogen in wastewater emissions in industrial and living is getting higher and higher, and the hydraulic eutrophication has caused people's high concern. The traditional biological nitrogen nitrogen is mainly nitrifying-denitrifying nitrogen, but due to its dependence on organic carbon sources, it is not suitable for treating low-carbon nitrogen than sewage. With the discovery of new biological nitrogen nitrogen, new biodeprofit nitrogen has been continuously developed. [0003] Anaerobium oxidation (Anammox) is a new type of biological nitrogen-nitrogen in recent years. It refers to in anaerobic conditions, ammonia is electron donor, nitrite...
