摘　　要：从活性污泥中筛选出具有较高絮凝活性的混合菌MBFH,研究了各种条件对混合菌产絮凝剂的影响.结果表明,混合菌MBFH产絮凝剂的最佳培养条件为:温度30℃、初始pH8.0、摇床转速为120r/min、培养基含糖量2%、相对接种量15%,其对高岭土悬浊液的絮凝率可达到88%.The mixed strains of MBFH that could produce flocculates were screened from activated sludge and the effects of some culture conditions on their flocculant production were studied. The optimum culture conditions of the mixed microbial MBFH were: temperature was 30 ℃, initial pH 8.0, agitation rate 120 r/min, the concentration of glucose in medium 2%, relatively inoculation 15%, and under these conditions the maximal flocculating rate to kaoline suspension about 88%.
