摘　　要：对四种不同的改性滤料去除水中有机物的效果进行了静态和动态吸附对比试验 .研究结果表明 ,改性滤料对有机物的去除效果始终优于原滤料 ,涂铁砂和涂铝陶对有机物的去除率达 66% ,静态和动态试验的结果均是涂铁砂对有机物的去除率最高 .In this paper static and dynamic analyses on the efficiency for removal of organic matter are made through four groups of absorption experiments with preparing coated media.It is found that the removal efficiency is better than uncoated medium.Both static and dynamic absorption experiments indicate that the best removal efficiency is produced with iron oxide coated sand.Besides,the experimental results are analysed in terms of surface properties of preparing coated media.
