水解酸化-生物接触氧化工艺处理生活污水

Domestic Wastewater Treatment by Hydrolytic Acidification/Biological Contact Oxidation Process

采用水解酸化-生物接触氧化工艺处理生活污水,处理水量为1 000 m^3/d。运行结果表明:该工艺处理效率高,抗冲击负荷能力强。最终出水COD为52.8 mg/L、BOD_5为16.8 mg/L、NH_3-N、SS质量浓度分别为11.7、15.9mg/L,对COD、BOD_5、NH_3-N、SS的去除率分别达到78.9%、86.0%、70.8%、92.1%,满足城镇污水处理厂污染物排放标准一级B标准。

The combined process of hydrolysis acidification and biological contact oxidation was applied to treat domestic wastewater and the treatment capacity was 1 000 m^3/d.The running results showed that the combined process had high treatment efficiency and strong resistance to shock loading.The final effluent mass concentration of COD,BOD5,NH3-N and SS was 52.8 mg/L,16.8 mg/L,11.7 mg/L and 15.9 mg/L,respectively,with the remove rate of 78.9%,86.0%,70.8%and 92.1%,respectively.The effluent water quality could meet the first level B standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant（GB 18918-2002）.
