一、问题的提出虹吸滤池是快滤池的一种新型式,其工作过程一般分过滤和反冲洗两部分,过滤是利用有一定孔隙率的滤料层,吸附待滤水中的胶体杂质使水澄清的工艺过程;当滤料层达到了截污极限时,必须依靠在大流量反冲洗逆向流经滤料层,滤料颗粒在水流剪切和相互摩擦碰撞过程中,使滤料表面截留的泥渣脱落,从而使滤料层迅速恢复工作状态,据水厂实际运行经验表明虹吸滤池的自耗
First, the issue raised Siphon filter is a new type of fast filter, the general process of its sub-filter and backwash two parts, the filter is the use of a certain porosity of the filter layer, adsorption of water to be filtered to make the gel impurities Water clarification process; when the filter layer reaches the cut-off limit, you must rely on the large flow backwash reverse flow through the filter media, filter particles in the flow of shear and mutual friction collision, the filter surface retention Of the mud off, so that the filter layer quickly resume working condition, according to the actual operation of the water plant shows siphon filter consumable
