虹吸滤池改造实现气水混合反洗的方法

The Method of Air-water Backwash Achieved through Siphon Filter

虹吸滤池对保证污水处理出水水质、提高污水处理效果具有重要作用,而反洗方式决定了滤池运行周期的长短和反洗效率的高低。当前,国内相当一部分虹吸滤池限于当时的施工工艺和科技水平,仍以水反洗作为唯一反洗手段,大大影响了虹吸滤池的水处理效率,将其改造成以气水混合反洗为主的反洗方式已成为一种必然。结合邹县电厂一期污水站虹吸滤池改造,对如何在改造中实现气水反洗进行了介绍。

Siphon Filter to ensure that sewage treatment effluent quality,improve sewage treatment effect plays an important role,and decided by the filter backwash operation cycle of the length and level of efficiency of anti-washing.At present,a considerable portion of the domestic limited to the time of construction Siphon Filter technology and scientific and technological development,still-water wash,as the only means of anti-washing,which greatly affected the efficiency of water treatment Siphon Filter will be transformed into a gas-water Mixed Backwash Backwash based approach has become an inevitable necessity.In this paper,a Zouxian Power Plant Wastewater Treatment Station Siphon Filter transformation process,on how to achieve the transformation of Air-water wash and then discussed.
