摘要
着重探讨了A2/O工艺深度处理生活污水各种工艺条件的选择和优化。通过调节pH、温度、流量等影响因素,计算出各种工艺条件下污水中COD,NH3-N,SS去除率。结果表明A2/O工艺深度处理生活污水的最佳条件为:pH值为8,温度为24℃,流量为20t/h。
The study focused on selection and optimization of all kinds of conditions in the domestic sewage advanced- treatment by A2/O process. By changing temperature, pH and flow in turn, the removal efficiency of COD, NH3-N and SS was investigated. The results showed that the best condition of advanced treatment was achieved when pH was 8, flow was 20 t/h and temperature was 24 ℃.
