摘要
简述了规格化纤维过滤材料的发展历程。介绍了一种不对称构型的彗星式纤维过滤材料 ,并结合滤床特点 ,探讨了该过滤材料的运行性能。试验表明彗星式纤维过滤材料可实现高速过滤 ,并具有反冲洗耗水率低 (1 %~ 2 %) ,剩余积泥率低 (<2 %)
The history of the normalizing fibrous filtering material is presented. A new asymmetric type of fibrous filtering material named cometic fibrous filter material was invented. The performance of this new filter media was discussed according to the features of the filter bed. It is indicated from the pilot scale tests that the filtering velocity could reach 40~100 m/h, and that the ratio of the backwash water was below 1%~2%, and that the proportion of residual sludge was below 2%.
