Abstract

The present invention provides a method for enrichment culture of Anammox. According to the method, seven steps are performed to finally produce Anammox-rich active sludge, such that the MLSS in the anaerobic bioreactor is 20-35 g / L, and the sludge retention time in the anaerobic MBR membrane bioreactor (AnMBR) is up to 180-300 days, wherein a flow rate ratio of the anaerobic microorganism-rich liquid refluxing to the anaerobic bioreactor from the anaerobic MBR membrane bioreactor (AnMBR) to the effluent filtered by the MBR membrane bioreactor is 3:1. According to the present invention, with the method, no Anammox loss exists, the high-quality and stable living environment is provided for Anammox, Anammox is subjected to enrichment culture, and the anaerobic ammonium oxidation reaction starting time can be shortened to 6-8 months; and the method further has advantages of simple process, safety, stability, low treatment cost, small occupation area, short hydraulic retention time, and fast anaerobic ammonium oxidation reaction starting.

Description

technical field [0001] The invention relates to a method for enriching and cultivating anaerobic ammonia oxidizing bacteria (Anammox). Background technique [0002] Traditional biological denitrification usually adopts nitrification-denitrification process, which has a long process flow, large floor area and high infrastructure investment. In the nitrification stage, aerobic nitrifying bacteria convert ammonium ions (NH 4 + ) into nitrate (NO 3 - ), mainly by two types of microorganisms, ammonia oxidizing bacteria and nitrite oxidizing bacteria, ammonia oxidizing bacteria oxidize ammonia to nitrite, nitrite oxidizing bacteria oxidize nitrite to nitrate; denitrification section, heterotrophic The denitrifying bacteria convert the nitrification product nitrate into nitrogen gas, realizing the denitrification treatment of wastewater. However, the problem of the traditional biological denitrification process is becoming more and more prominent. In order to convert ammonia n...
