摘　　要：在无外加碳源的静态试验条件下,用4种微生物菌剂进行水质净化效果研究。结果表明:4种微生物菌剂对水中氮磷的降解效果明显,但对COD的降解效果不甚理想;对TN及NH3+-N的去除效果,脱氮菌显著大于复合芽孢杆菌和硝化细菌;4种微生物菌剂投至水体中其微生物菌群均在7d左右开始进入衰亡期。In the absence of external carbon source, the effect of water purification by the four kinds of microbial a- gents is tested under the static conditions. The results show that they all have a high performance in the degradation of nitrogen and phosphorus, but not for CODor. For the removal of TN and NH3＋ - N, the denitrification bacteria are better than the composite bacillus and the nitrifying bacteria. After 7 days of being put in the water, the flora of all four microbial agents starts to decline.
