摘要
传统的双层滤料滤池在反冲洗时要同时排水，滤料损失、滤料混层和易积泥球的现象影响了滤池的推广使用。
For the conventional dual layer filter the wastewater overflows simultaneously during the backwashing operation and so the loss of some filtering media is caused. Besides some unfavorable factors such as the congestion of filtering layers and accumulation of sludge balls blocked up the promotion of dual layer filters. A new non overflow dual layer filter that is build without simultaneous overflow at time of backwashing and widely applied abroad is presented in this paper.
