Abstract:

The treatment effects of six kinds of flocculants on domestic sewage are studied. Flocculant LF-Tou2 has been chosen and its flocculating efficacy is optimized by uniform design. The results show that the COD removing rate from domestic sewage is 92.9%, when pH is 7.5, dosage 19 mg/L, temperature 27℃, and stirring time 3 min.

Key words: microbial flocculant, domestic sewage, flocculation

摘要:

研究了6种絮凝剂对生活污水的处理效果, 选出絮凝剂LF-Tou2, 通过均匀实验对其絮凝效果进行优化。实验结果表明:当pH为7.5、添加量为19 mg/L、温度27℃、搅拌时间为3 min时, 生活污水COD去除率为92.9%。
