Abstract：The effect of different organic matters on nitrogen removal performance of anammox coupling heterotrophic denitrification process was investigated by continuous cultivation and serum bottle batch tests. In view of TN removal rate, the results showed that the sequence of these orgnic matters’ influence on the coupling reactor was (from minimum to maximum): sodium benzoate, o-dihydroxybenzene, m-dihydroxybenzene, sodium propionate, sodium acetate;. sodium benzoate, o-dihydroxybenzene, m-dihydroxybenzene, sodium propionate and sodium acetate have a little impact on the anaerobic ammonia oxidation bacteria. Phenol denitrifying bacteria could use sodium benzoate, o-dihydroxybenzene, m-dihydroxybenzene, sodium propionate and sodium acetate as electron donor for denitrification. Different organic matters had different influences on phenol denitrifying bacteria and then affected the cooperative and competitive relationship between phenol denitrifying bacteria and anaerobic ammonia oxidation bacteria. Benzoic acid was the possible product of phenol degradation.
