摘　　要：由于五味子提取液废水具有高COD、高氨氮和可生化性差的特性,具有较高的处理难度。湖北省某只要企业受限于污水处理成本,采用多级生物法,即水解酸化-A/O-兼氧-MBR组合工艺进行污水处理。该工艺处理水量为180 m^(3)/d。运行结果表明,该工艺处理效果稳定,COD、氨氮去除率均达到98%以上。The wastewater from Schisandra chinensis extract has characteristics of high COD,high ammonia nitrogen and poor biodegradability,which is difficult to be treated.Limited by the cost of sewage treatment,a certain enterprise in Hubei province adopts the multi-stage biological method,namely the combined process of hydrolytic acidification-A/O-facultative-oxygen-MBR to treat wastewater.The water volume of this process is 180 m^(3)/d.The operation results show that the treatment effect is stable and the removal rate of COD and ammonia nitrogen reaches more than 98%.
