摘　　要：介绍了氧化铝涂层石英砂和未涂层石英砂对微污染原水进行直接过滤的研究结果：无论对浊度，还是对有机物的综合去除，氧化铝涂层砂滤料过滤效果均明显优于未涂层砂滤料。Aluminum oxide coated sand as filter media was compared with common sand for direct filtration of micro polluted raw water and described in this paper. The study results showed that the coated medium was better evidently than the uncoated one in both turbidity removal and organic removal.
