摘要: 为了研究超滤、(UF) 技术对地表水的处理效果,建造了一座120 吨/天的中试规模的膜处理水厂.以松花江水为水源,用粉末活性炭(PAC) 吸附作为超滤的预处理工艺,组成了PAC-UF 系统.结果表明:PAC-UF 工艺的出水浊度在0.15 NTU 左右,而且不受进水浊度的影响;原水不经过PAC 吸附直接起滤时,膜出水有机物浓度和膜进水有机物浓度存在线性关系;UF 对UV254的平均去除率在10% 左右,对溶解性有机破(DOC) 的平均去除率在8% 左右;加入PAC 吸附后对有机物的去除有明显提高.

Abstract:

In order to reveal the efficiency of ultrafiltration (UF) process to the treatment of surface water , a water treatment pilot-plant with a capacity of 120 t/d was set up. In this plant , the water in the Songhua River was used as the raw water, and powdered activated carbon (PAC) absorption was performed to pre-trea the water before the ultrafiltration , thus forming a PAC-UF system. The results show that (1) independent upon the turbidity of the raw water , the turbidity of membrane permeation is only 0. 15 NTU; (2) after the ultrafiltration without PAC pretreatmen,the organic concentration of ultrafiltrated permeation presents a linear correlation with that of the raw water ,and the average removals of UV 254 and dissolved organic carbon (DOC) reach 10% and 8% , respectively; and( 3) the addition of PAC obviously improves the removal of organic matters.
