水解酸化-生物接触氧化工艺处理小区污水

Treatment of Wastewater in City District by Hydrolytic,Acidification and Biological Contacting Oxidation Process

某城市居民小区污水处理站设计规模为 1 0 0m3/d ,采用水解酸化—生物接触氧化工艺 ,在进水BOD为 86mg/L、COD为 2 1 5mg/L、SS为 1 1 6mg/L、NH3-N为 2 8mg/L的条件下 ,处理后出水BOD <2 0mg/L、COD <60mg/L、SS<2 0mg/L、NH3-N <1 5mg/L ,达到《污水综合排放标准》(GB8978-1 996)

The hydrolytic acidification, biological contacting oxidation process has been adopted to treat the wastewater with capacity of 100 m 3/d in the city district. An effluent with BOD<20 mg/L, COD<60 mg/L, SS<20 mg/L, NH 3-N<15 mg/L has been obtained when the inlet BOD,COD, SS and NH 3-N are 86 mg/L, 215 mg/L, 116 mg/L and 28 mg/L, respectively. It meets the national wastewater discharge standard.
