中空纤维超滤膜净化长江水的试验研究

Experimental Study on Hollow Fiber Ultrafiltration Membrane for Changjiang Water Purification

研究了超滤膜净化长江水过程中净化水水质和过滤性能的变化,比较了不同操作压力和不同反冲周期的条件下,膜通量和产水量的变化情况。结果表明,采用超滤膜直接过滤原水,出水水质良好,产水量较大,运行稳定。

This paper studies the difference of water quality and filtration characteristic in the purification process of ultrafitration membrane for Changjiang water, and compares the changes of flux and production under the condition of different operating pressure and different backwater periods. The results showes that UF is used to directly process the raw water to get good water quality, great output and stable operation.
