摘要 基于活性污泥法与曝气生物滤池(BAF)的特点,开发了一种新型组合工艺——由活性污泥/曝气生物滤池构成的A/O工艺。在进水流量为6.8L/h、回流比为200%、总HRT为1.2h、BAF的气水比为10∶1、水温为16.5~19.2℃的条件下,考察了该工艺对生活污水的处理效果。试验结果表明,该工艺具有良好的除碳脱氮性能,对COD、NH3-N、TN、TP和SS的平均去除率分别可达94.2%、85.3%、63.6%、33.1%和91.4%,且具有能耗低、占地少、运行管理简便等优点。 The treatment efficiency of domestic sewage was investigated under the conditions of influent rate of 6.8 L/h, reflux ratio of 200%, total HRT of 1.2 h, BAF's air/water ratio of 10 : 1 and water temperature of 16.5 ℃ to 19.2 ℃. The experiment results indicate that the combined process has a good efficiency of carbon and nitrogen removal. The average removal rates of COD, NH3 - N, TN, TP and SS reach 94.2%, 85.3%, 63.6%, 33.1% and 91.4% respectively. It has advantages of low energy consumption, less land occupation and easy management.
