摘　　要：采用常规的细菌分离纯化方法从污水处理厂活性污泥中分离出絮凝剂产生菌菌种,经过驯化培养后,以发酵液对高岭土混悬液的絮凝效果为指标,选取培养较好的一种,采用正交试验设计方法,分析了影响絮凝效果的主要因素,结果表明:培养温度为30℃,pH为7.0,葡萄糖为碳源,摇床转速140r/min,培养72h时,絮凝效果最好。A strain of microorganism which produces flocculant was isolated from activated sludge. Through orthogonal test the optimum cultural conditions were found with kaolin clay suspension flocculation. The optimum cultural condition is cultural temperature 30℃, primary pH 7.0, rotate speed 140 r/min, carbohydrate glucose.
