摘　　要：在实验室条件下对产絮菌H8絮凝条件进行优化,得出所需最佳碳源为葡萄糖;最佳复合氮源为酵母菌+蛋白质;最佳生长环境PH为8;培养温度为10℃,培养时间为20h。最佳絮凝条件:高岭土PH为9.0;助凝剂为Ca2+,加入Ca Cl2的最佳浓度为0.04%,菌液投加量为2%,静沉时间5min。We optimize flocculation conditions of Flocculant producing bacteria H8 in laboratory.conditions , it is concluded that the best carbon source is glucose; The best compound nitrogen source of yeast ＋ protein; Optimal growth environment PH 8; Cultivation temperature is 10 ℃, time is 20 h. The optimum flocculation conditions ： kaolin PH 9.0; Coagulant aid was Ca2 ＋, the optimal concentration of Cacl2 is 0.04% , microbial additive amount was 2%, the Static sink time is 5 min.
