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.

Key words: surface water, water treatment, ultrafiltration membrane, turbidity, organic matter
