摘要 以单层滤料直接过滤为例,测试分析滤层中水头损失的变化规律,结果表明,滤池中绝大部分悬浮颗粒均被截留在表层滤料中,用少量空气先冲洗表层滤料,再用少量水反冲洗滤层,可以取得满意的冲洗效果. Based on the example of direct filtration of single-layer filtering medium , the change law of head loss in the filter layer is analyzed. The result show that the majority of suspended solids in the filter are lived in the surface filtering medium. A satisfying effect can be achieved by a new method that firstly small quality of air is used to wash surface filtering medium and then small quality of water is used to backwash filtering medium repeatealy.
