摘　　要：实验通过采用6种超滤膜对某海域高浊度海水进行反渗透前的预处理，结果显示，超滤出水浊度〈0．2NTU，SDI％3，对细菌的去除率大于99％，对水中的有机物、胶硅、铁的去除率分别为10％～80％，40％～85％和60％～90％．不同类型的超滤膜通过周期性的反洗可以使跨膜压差有较好的恢复率，这表明了超滤作为高浊度海水反渗透预处理是可行的．The six various ultrafiltration membranes were used to pretreat high turbidity seawater prior to reverse osmosis. Experimental results showed that turbidity of permeant water reached below 0.2NTU, and SDI below 3. The ultrafiltration also removed more than 99% bacteria, 10%-80% organic matters, 40%-85% colloid silicon and 60%-90% iron. TMP of all the six membranes recovered well after backwashed periodically. It is shown that it is possible to pretreat high turbidity seawater by the ultrafiltration.
