改良型氧化沟污泥膨胀的发生及控制措施

Sludge bulking in improved oxidation ditch and controlling measures

结合改良型氧化沟处理文化用纸生产废水的工程实例,介绍了此次污泥膨胀的发生和控制过程。分析发现,进水浓度和化学品引起的泡沫是此次污泥膨胀的主要原因。

With reference to an engineering example in treating effluent from a fine paper machine with improved oxidation ditch, the generation and control process of the sludge bulking are introduced. It has been found that the concentration of influent and effluent and the foam caused by paper chemicals are the main causes of the sludge bulking.
