Abstract
Ultra filtration (UF) using hollow-fiber membranes is being developed in the field of drinking water purification.In China, surface water is polluted in some regions where an advanced treatment facility should be constructed to produce safe drinking water. However, it is limited because of some problems associated with its direct use, which includes membrane flux decline and insufficient removal of dissolved organic matter. This study examined the effect of pretreatment by coagulation and rapid sand filtration on membrane performance. An ultrafiltration system with a capacity of 120 m3/d was constructed to purify raw water taken from the Songhuajiang River near Harbin in northern China.

摘要
超滤（联阵）利用中空纤维膜正在开发领域的饮用水净化.在中国，地表水的污染在一些地区，先进的处理设施应建造生产安全的饮用水。然而，它是有限的，因为一些问题与它的直接使用，其中包括膜通量下降，不足以消除溶解的有机物质。本研究预处理混凝和快速砂滤对膜的性能。一个超滤系统容量为120立方米/ D获得建造净化原水取自松花江哈尔滨北部靠近中国。
