摘要：

采用高效曝气生物滤池(BAF)工艺处理生活污水，经监测处理后出水的COD_Cr、BOD₅、SS等各项污染物指标均大大优于《生活杂用水水质标准》(CJ25.1—1989)中的要求，出水中COD_Cr≤20mg/L，BOD₅≤3.5mg/L，SS≤1.0mg/L。该BAF工艺投资少，处理效率高，操作简单，值得在大型污水回用处理工业领域推广应用。

Abstract:

The highly efficient biological aeration filter-cell(BAF) process has been used in the treatment of sewage, and the results indicate that the specifications of COD_Cr,BOD₅,SS in the treated water are much better than the requirements in quality standard of domestic water (CJ 25.1-1989), the average concentrations of the treated water are: COD_Cr≤20 mg/L, BOD₅≤3.5 mg/L, SS≤1.0 mg/L. This BAF process is of such excellent properties as less investment, high efficiency and simple operation, which deserves popularization and application in the field of sewage reused treatment industry.

Key words: domestic sewage, hydrolytic acidation cell, biological aeration filter-cell
