Abstract:

COD and BOD of the inflow of aeration basin and the effluent of secondary sedimentation tank were detected through orthogonal test.The test use removal rate of COD and BOD as evaluation index, B/C as analysis index. The result of the test indicated that the best working condition can be achieved when there are 3 water pumps for inflow, the concentration of activated sludge stands at 1600mg/L, and HRT in the aeration basin and secondary sedimentation tank stand at 1.86 hours and 2.87 hours respectively. The test demonstrated that short-time aeration can reduce the energy consumption and, therefore, the cost effectively, while insure the effluent reach the outlet qualitative standard. This is suitable for sewage treatment plants in south China since the concentration of their inflow is low.
