摘要
南方某城市污水厂采用MSBR工艺,对发生污泥膨胀的原因进行了分析,认为污泥膨胀是由进水含有油类物质和曝气池DO低造成的。该厂通过工艺调整,投加助凝剂、灭菌剂,对曝气池进行改造,使污泥膨胀得到有效治理。
The MSBR process is used in a municipal wastewater treatment plant in Southern China. The causes for sludge bulking in MSBR process are analyzed. It is believed that the sludge bulking is caused by oil in the influent and lower DO in the aeration tank. The sludge bulking problem has effectively treated by regulating the operation parameters, adding coagulant aid and sterilizing agent and reconstructing the aeration tank.
