污水处理厂污泥膨胀和污泥发泡的比较分析
Comparative analysis of sludge bulking and sludge foaming in wastewater treatment plant
【摘要】 活性污泥法由于操作简单、处理效果好被广泛应用于市政污水和工业废水的处理。污泥膨胀和污泥发泡现象影响二次沉淀池的泥水分离过程和生物反应池的微生物量稳定,严重困扰着污水处理厂的正常运行,被称为污水处理厂的"癌症"。本文从污泥膨胀和污泥发泡的定义及分类出发,全面地比较了表征污泥膨胀和污泥发泡的方法、引起污泥膨胀和污泥发泡的丝状细菌种类及控制污泥膨胀和污泥发泡方法的异同,并探讨了污泥膨胀和污泥发泡问题的未来研究方向和控制策略,期望能够为今后污泥膨胀和污泥发泡问题的研究和调控提供有价值的参考。
【Abstract】 Activated sludge(AS) process is the most widely process in wastewater treatment because of its simple operation and good treatment effect. Sludge bulking and sludge foaming, known as the "cancer" of wastewater treatment plants(WWTPs), affect the solid-liquid separation process of the secondary sedimentation tank and the stability of the microbial biomass in the biological reaction tank, which have long troubled the operation of WWTPs. The definition, classification, characterization methods,filamentous bacteria, and control methods of sludge bulking and sludge foaming were compared and analyzed as comprehensively as possible in this review. In addition, the future research direction and control strategy of sludge bulking and sludge foaming were discussed. It is expected to provide helpful information for future research on sludge bulking and sludge foaming.
