摘　　要：通过实验考察F2–F6复合型微生物絮凝剂分别与无机絮凝剂氯化铝、无机高分子絮凝剂聚合氯化铝、有机絮凝剂聚丙烯酰胺复配使用处理泥浆废水絮凝条件和絮凝效果,并对水源水和工业废水中的处理效果进行了测定。实验结果表明:F2–F6微生物絮凝剂与化学絮凝剂配合使用不仅获得了更好的净化效果,而且可大大降低絮凝剂的总投加量。The flocculation conditions and performance of the treatment of slurry water by using complexation of F2-F6 compound microbial flocculant and respectively inorganic flocculant AlCl3, inorganic high molecular flocculants PAC, and organic high molecular flocculants PAM were studied and their efficiency values for treating raw water and waster water was also measured. The results showed that complexation of F2-F6 compound microbial flocculant and general chemical flocculant can not only result in the reduction of flocculants usage but also bring about better purification result.
