V型纤维滤池在城市污水深度处理中的设计及运行

Design and operation of V type fiber filter in advanced treatment of municipal sewage

介绍了V型纤维滤池的工艺设计和运行。运行数据表明，在进水p（SS）〈20mg／L、p（CODCr）〈30mg／L、浊度〈12NTU的条件下，SS和浊度去除率为80％以上，COD0去除率为15％--20％。旋翼纤维滤料的纳污量为7．8kg／m2，反冲洗耗水量仅为过滤水量的2．7％，能反洗出90％以上的截污量。

The design and operation of V type fiber filter were introduced. The operating data showed that, under the condition that the mass concentrations of SS, CODcr in the influent water were lower than 20 and 30 mg/L respectively, the turbidity was lower than 12 NTU, the removal rates of SS and turbidity were both above 80%, and the removal rate of CODcr was 15% - 20%. The pollutant retention capacity of rotary-wing shaped fiber filter materials was 7.8 kg/m3, the backwashing water consumption was only 2.7% of the filtration water quantity, above 90% of pollutant can be backwashed.
