摘要
研究了超滤膜(UF)处理生活污水站出水的阻力特性及清洗的可恢复性,对MF、活性炭吸附、活性炭吸附+MF、混凝等UF预处理方法进行了试验。平膜试验结果表明,活性炭+MF或混凝作预处理,过滤阻力显著降低,清洗的恢复性较好。
A study on the characteristics of the resistance in the treatment of the first grade effluent from the sewage farm and the cleaning recoverability by UF membrane is carried out.The experiment of pretreatments prior to the UF process is conducted. The tested pretreatments are on MF,GAC,GAC+MF and coagulation. The flat sheet test shows that GAC+MF or coagulation can reduce the resistance in membrane filtration greatly and the cleaning recoverability in membrane is good with pretreatment of GAC+MF or coagulation.
