微生物絮凝剂NII4处理生活污水的研究

The study on the treatment of domestic sewage by microbial flocculant NII4

利用产絮凝剂菌代谢生成的微生物絮凝剂(NII4)处理西安市第四污水处理厂进水水样,通过实验研究发现,该微生物絮凝剂(NII4)对城市生活污水的SS和COD有良好的去除效果。针对西安市第四污水处理厂进水,在絮凝剂投加量为40 mg/L的条件下,SS去除率可达到86%,COD去除率可达39.25%。

A strain of bioflocculant - producing bacterial could produce microbial flocculant （ named NII4）. This paper uses NII4 to study the treatment of influent sample from Xi＇ an No. 4 Wastewater Treatment Plant. The result shows that NII4 could get a good removal rate of SS and COD in domestic sewage. When the dosage of NII4 is 40 mg/L, the removal rates of SS and COD are 86% and 39.25%, respectively.
