摘要:
以某城镇污水处理厂为例，分析了城镇污水处理厂运行中二沉池浮泥产生的主要原因。通过全流程测试分析和内源呼吸反硝化实验，发现好氧池末端低DO浓度、活性污泥良好的脱氮性能和内源反硝化特性的共同作用是导致二沉池浮泥产生的主要原因。通过提高好氧池末端曝气量，有效解决了二沉池污泥上浮问题。该全流程测试分析方法对污水处理厂的运行管理具有重要的参考价值。
Abstract:
The main causes of floating sludge in secondary sedimentation tank during the operation of a sewage treatment plant were analyzed. Through the whole process test and analysis and endogenous respiration denitrification experiments, it was found that low DO concentration at the end of the aerobic tank, good denitrification performance of activated sludge and endogenous denitrification were the main reasons for the formation of the floating sludge in the secondary sedimentation tank. The problem of the floating sludge in the secondary sedimentation tank was effectively solved after increasing the aeration flow rate at the end of the aerobic tank. The proposed whole process test and analysis method has important reference value for the operation and management of sewage treatment plant.
