某企业污水站活性污泥膨胀的影响因素与控制研究

Study on the influencing factors and control of activated sludge bulking in a wastewater treatment station

针对某化工仓储企业产生的大量有毒有害高浓度有机物工业废水较难处理的情况,采用了改良型SBR(活性污泥法)工艺。简单介绍了企业污水站污水改良型SBR工艺,分析了在处理废水期间发生丝状菌性污泥膨胀的影响因素,并提出了控制方法,为有效控制实际运行中出现的污泥膨胀问题提供了依据。

In view of the difficulty to deal with a large amount of toxic and harmful organic wastewater with high concentration from a chemical storage enterprise, the improved SBR process was adopted. The modified SBR process was briefly introduced, the influencing factors on filamentous bacteria sludge bulking during the operation process at the wastewater station in a chemical storage enterprise were analyzed, and the control method was put forward, thereby providing a simple basis for the effective control of the sludge bulking in the actual operation.
