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25 m/h时,截污容量为5.5 kg/m3,SS去除率为93.04%,CODCr去除率为27.6%。另外水头损失7.84×10-3 MPa,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。
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/m^3, the removal rate of SS is 93.04% ,the removal rate of CODc, is 27.6% ,head loss is 7.84× 10^-3 MPa,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.
