摘　　要：利用分离筛选出1株对制药废水有较强絮凝效果的絮凝剂产生菌G13；该菌株培养18～24h的菌液絮凝活性最高；该菌株所产絮凝剂对某制药废水的最佳絮凝条件为：菌液质量分数为50％，絮凝时间为6h，温度为30℃，pH为6．0。利用培养18h的G13菌液对某制药废水进行处理，在菌液质量分数为50％，絮凝时间为4h，温度为30℃，pH为6．0的絮凝条件下，制药废水的CODcr去除率为35．19％，色度去除率为75％，浊度去除率为59％，臭度由5变为3。One flocculant producing bacteria with good effect of flocculation is screened from the soil, which is named as G13. The flocculent activity of G13 can reach its highest extent after 18 - 24 hours of culture. The best flocculation condition for pharmaceutical wastewater is optimized by using the orthogonal experiment. The best flocculent conditions are ：50% of the bacteria content ,6 hours of the flocculating time ,30℃ of the temperature and pH 6.0. The result of pharmaceutical wastewater treatment shows that under the best flocculent condition, CODcr, removal rate is 35. 19% ,the chromaticity color removal rate is 75% ,the turbidity removal rate is 59% ,and the odor is reduced from 5 to 3.
