地埋式循环滤料曝气生物滤池处理博物馆污水

Treatment of Museum Wastewater by Underground Circulating Filtering Media BAF

采用以循环滤料曝气生物滤池(BAF)为主体的地埋式一体化设备处理博物馆污水。运行结果表明,设计水量为80m3/d,进水COD、SS、NH3-N平均浓度分别为320、200、40mg/L时,处理后出水相应指标分别降至45、30、8mg/L,出水水质达到《污水综合排放标准》(GB 8978—1996)的一级标准。

The underground integrated equipment mainly composed of circulating filtering media BAF was used to treat museum wastewater. The treatment capacity is 80 m^3/d. The operation results show that the average effluent concentrations of COD, SS and NH3 - N are below 45 mg/L, 30 mg,/L and 8 mg/L when the average influent concentrations of COD, SS and NH3 - N are 320 mg/L, 200 mg/L and 40 mg/L respectively. The effluent quality meets the first level criteria specified in the Integrated Wastewater Discharge Standard （GB 8978 -1996）.
