| 摘 要： | 对两级曝气生物滤池(上向流-下向流)处理生活污水进行了试验研究。试验表明,两级曝气生物滤池在水力负荷小于4m/h,进水COD浓度变化范围为100~500mg/L,一级气水比为3∶1~5∶1,二级气水比为1∶1~2∶1的条件下,出水水质稳定,出水水质达到生活杂用水水质标准。

| Abstract: | This paper focused on the experimental study on the Two-stage Biological Aerated Filter(up-flow and down-flow) for municipal wastewater treatment.The results show that the effluent quality is acceptable and can meet the requirements of the water quality standard for domestic miscellaneous uses when the hydraulic loading less than 4m/h and the inlet COD content is between 100～500mg/L with the first stage air-water ratio being 3∶1～5∶1 and the second stage being 1∶1 ～2∶1. |
