摘　　要：采用陶粒滤料处理微污染原水,研究了具有不同结构特性的陶粒滤料对有机物、藻类及浊度的去除效果。结果表明:对高锰酸盐指数的去除率>25,最高可达38;对氨氮的去除率>60,最高为70;对亚硝酸盐氮的去除率>98;对藻类的去除率可达95以上;出水浊度<1NTU。此外,具有较大的比表面积、发达的孔隙及较多的连通等特性的陶粒处理效果好,适合作为水厂工艺改进的首选滤料。Ceramsite filtering materials were applied to treat the micro-polluted raw water. The remoral efficiencies of organics, algae and turbidity by the ceramsite filtering materials with different structures and characteristics were investigated. The results show that the removal efficiencies of organics （represented by permanganate index）, ammonia nitrogen, nitrite nitrogen and algae are more than 25% （ up to 38% ）, more than 60% （ up to 70% ）, more than 98% and more than 95% respectively. The effluent turbidity is all less than 1 NTU. Accordingly, the ceramsite filtering materials with large specific surface area, abundant pores and connections are the first choice for the process improvement in waterworks.
