摘 要:采用无动力地埋式厌氧生物滤池/生态浮床组合工艺处理坑贝村生活污水,其中厌氧生物滤池可有效降解有机物,生态浮床则可进一步脱氮除磷。实际运行结果表明,该组合工艺效率高,出水水质稳定且达到广东省地方标准《水污染物排放限值》第二时段一级标准,出水平均浓度SS<20 mg/L、COD<40 mg/L、BOD5<20 mg/L、NH+4-N<10 mg/L、TP<0.5 mg/L,其对应的SS、COD、BOD5、NH+4-N、TP平均去除率分别为89.7%、81.0%、80.9%、80.9%和81.9%。同时,该工艺具有占地少、投资少、能耗低、运行费用低、维护管理容易等特点,适用于南方地区农村生活污水处理。The combined process of underground unpowered anaerobic biological filter and ecologi- cal floating bed was used to treat rural domestic sewage in Kengbei village. The anaerobic biological filter could effectively degrade organic substances and the ecological floating bed could further remove nitrogen and phosphorus. The operation results showed that the combined process had good and stable removal ef- ficiency. The effluent quality met the first class criteria (the second period) specified in the Discharge Limits of Water Pollutants ( DB 44/26 - 2001 ) of Guangdong Province. The average effluent concentra- tions of SS, COD, BODs, NH4 _ N and TP were less than 20 rag/L, 40 rag/L, 20 rag/L, 10 mg/L and 0.5 mg/L respectively, and their average removal rates were 89.7% , 81.0% , 80.9% , 80.9% and 81.9% respectively. Furthermore, the combined process exhibits advantages such as small footprint, low cost, low energy consumption, low operation cost, easy maintenance and management. It is suitable for treatment of th,~ ~,r~] Ar .. .__ .,
