摘要：

介绍了V型纤维束滤料滤池的工艺设计和运行。某污水厂现场试验表明，滤速为25m/h时，截污容量为5.5kg/m3，SS去除率为93.04%，COD_Cr去除率为27.6%。另外水头损失7.84×10-3MPa，剩余积泥率≤0.5%-1%，自用水耗为周期制水量的1%左右，具有很高的经济运行性。

Abstract:

The design and operation of V-style fiber filter tank is introduced.According to the experiments on the spot in a wastewater plant,when filtration velocity is 25 m/h,the retaining capacity is 5.5 kg/m³,the removal rateof SS is 93.04%,the removal rate of COD_Cris 27.6%,head loss is 7.84<10^-3MPa,residual sludge rate is ≤0.5%-1%,water backwashing rate is about 1% of specific water yield,which indicate V-style fiber filter tank has high economical operating nature.

Key words: V-style fiber filter tank, fiber bundles, air and water backwashing
