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。

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.
