China Environmental Science, 2017,37(4)：1315~1321 Abstract ：The inhibition effect of three different kinds of antibiotics on the nitrogen removal performance of anammox granules was investigated by serum bottle batch tests. The antibiotics used in the experiment were penicillin G sodium, oxytetracycline HCl and polymyxin E sulphate, which performed different inhibition mechanisms. As a result, when the batch test was co
