摘　　要：采用双斜板槽反应器，结合翻耕操作在SBR方式下交替运行，从而实现连续处理生活污水，并重点研究了对COD、氨氮、总氮、磷的去除能力。结果表明，在Ⅰ号和Ⅱ号反应器交替运行和水力负荷为0．01m^3／（m^2·d）以及进水COD、氨氮、TN分别为（61～439）、（10．2～28．19）、（25．07-47．49）mg／L的条件下，整个系统对上述指标的平均去除率分别达到80．27％、84．73％、74．28％。可见，双斜板槽土地处理系统结合翻耕技术可实现对生活污水的高效净化。Double inclined plate tank reactors combined with ripping operation were used to treat domestic sewage continuously under the condition of alternate operation of SBR. The removal efficiencies of COD, ammonia nitrogen, TN and phosphorus in sewage by the reactors were investigated. The results showed that under the conditions of alternate operation of Ⅰ and Ⅱ reactors and hydraulic loading of 0.01 m^3/（m^2·d）, when the influent concentrations of COD, ammonia nitrogen and TN were 61 to 439 mg/ L, 10.2 to 28.19 mg/L and 25.07 to 47.49 mg/L respectively, the corresponding average removal rates in the whole system were 80.27%, 84.73% and 74.28% respectively. It was thus clear that double inclined plate tank reactors combined with ripping operation could achieve high-efficiency purification of domestic sewage.
