rapid enrichment of anammox bacteria
Rapid cultivation and enrichment of anaerobic ammonia oxidation bacteria (AnAOB) is a challenge due to their slowly growing rate. Strategies of substrate supply could greatly influence on AnAOB yield and anammox performance. In this research, the feeding strategy of low nitrogen strength with constant ammonium concentration and gradient-decreasing hydraulic retention time was investigated in an up-flow sludge blanket reactor
