提高滤池对天然水或污水的过滤效果的方法之一,是运用新的滤料。目前,除了采用传统的砂和无烟煤作滤料之外,正越来越多地应用陶粒、烧岩、火山渣和其他一些物质作为滤料。用漂浮材料来替代现在使用的重滤料可在本质上改变滤池的工艺流程。和用石英砂 One of the ways to improve the filtering effect of the filter on natural water or sewage is to use a new filter material. At present, besides using traditional sand and anthracite as filter materials, ceramics, fired rock, volcanic slag and other substances are increasingly being used as filter media. Replacing the currently used heavy media with a floating material can fundamentally change the process flow of the filter. And use quartz sand
