Abstract: The present invention relates to a method for highly efficient in-situ enrichment of anaerobic ammonium oxidizing bacteria (AnAOB), which comprises: using anaerobic digestion sludge as inoculum sludge, nitrate wastewater as influent in the experimental group, ammonium and nitrite wastewater as influent in the control group. The inoculum sludge and influent are reacted under conditions of light avoidance, constant temperature, and anaerobic environment to enrich AnAOB. Compared with existing technology, the present invention uses anaerobic digestion sludge as inoculum sludge and nitrate wastewater as influent to enrich AnAOB. After about 30 days of operation, the absolute abundance of AnAOB functional genes HzsB increased by about 100 times compared to the control group (6.90E+04 copies/ng DNA?6.73E+06 copies/ng DNA).
