摘　　要：采用混凝/沉淀/超滤组合工艺处理滦河水并进行现场中试。结果表明,超滤膜具有良好的除浊功能,对CODMn、UV254与DOC也有一定的去除效果,出水水质稳定。预氯化能够提高超滤膜对CODMn与UV254的去除率,且有助于减缓比通量的衰减,但预氯化只是改善了超滤膜的透水通量,并没有从根本上消除膜污染。The combined process of coagulation, sedimentation and ultrafiltration （UF） was used to treat the raw water from the Luan River in a pilot-scale experiment. The results show that the UF can remove turbidity effectively and remove CODMn, UV254 and DOC to a certain extent. The quality of the permeate is stable. Prechlorination can improve the removal rates of CODMn and UV254 and contribute to alleviation of the specific flux attenuation. But prechlorination can only improve the permeate flux, it does not remove the membrane fouling indeed.
