摘　　要：通过对有效微生物群(EM)的富集培养液的絮凝试验,从中挑选出酵母菌、光和菌有较好的絮凝性能。进一步实验结果表明,酵母菌的最佳培养条件为:好氧条件下,30℃恒温培养,絮凝培养24 h即可达到最大絮凝率94.58％,培养基的最佳初始pH值为6.5。光和菌的最佳培养条件为:厌氧条件下,30℃恒温培养,絮凝培养36 h即可达到最大絮凝率93.48％。光和菌、酵母菌发酵液最佳的投加体积百分数均为2％。A flocculation test conducted with cultivation solution of Effective microorganisms( EM) shows that photosynthetic bacteria and microzyme have the higher flocculation capability. Peeper experiment results show that the best culture conditions of microzyme is to put the culture medium under aerobic conditions, with the temperature of 30℃. The best pH of medium is 6.5. The best culture conditions of photosynthetic bacteria is to keep the culture medium under anaerobic, with the temperature of 30℃, growing 36 hours.
