一体化IFAS工艺处理农村生活污水

Rural Domestic Wastewater Treatment by IFAS Integrated Process

采用一体化IFAS工艺对某城镇农村生活污水进行处理,考察其对污水中的有机物及含氮污染物的去除能力。结果表明,当进水COD、NH_4^+-N和TN质量浓度分别为160~280 mg/L、21~48 mg/L和30~50 mg/L时,一体化IFAS工艺出水COD、NH_4^+-N和TN浓度均可满足城镇污水处理厂污染物排放标准一级A标准。因此,一体化IFAS工艺用于农村生活污水处理,对污染物具有较高的去除能力。

The IFAS integrated process was used forthe rural domestic wastewater treatment,the removal capacity for organics and nitrogen pollutant was researched.The results showed that,when the COD,NH4^-＋-N and TN concentration of influent was in the range of 160-280 mg/L,21-48 mg/L and30-50 mg/L,respectively,the COD,NH4^-＋-N and TN concentration of effluent treated by IFAS integrated process could reach first class A level of the＇discharge standard of pollutants for municipal wastewater treatment plant＇.Therefore,the IFAS integrated process was able to improve the pollutant removal performance when treating the rural domestic wastewater.
