长兴水厂沉淀池反应区浮沫现象的探讨和解决方案

Discussion and solution of floating foam in the reaction zone of sedimentation tank in Changxing Waterworks

臭氧活性炭深度处理工艺运行后,预臭氧若采取微孔曝气方式投加,可能导致沉淀池反应区存在浮沫现象。根据浮沫产生的现象,分析了浮沫产生机理并针对性地进行系统分析、研究,最终采取喷淋措施,取得了较好的除沫效果。

During the operation of ozone activated carbon advanced treatment process, if pre-ozonation was added by microporous aeration, there may be floating foam in the reaction zone of sedimentation tank. According to the phenomenon of floating foam, the generation mechanism was analyzed, targeted systematic analysis and research were carried out, and finally the spray measures were taken to achieve good defoaming effect.
