摘　　要：对涂铁改性石英砂滤料进行了过滤吸附去除微量磷试验研究。结果表明,改性石英砂对总磷的去除率达90%以上。吸附试验获得的对溶解性总磷的吸附等温线属于Langmuir型,并得出涂铁改性石英砂的除磷吸附等温式。The phosphorus removal efficiency in drinking water filtration and absorption using modified quartz sand was studied. It was shown that total phosphoms（TP） removal rate was up to 90 percent. Phosphorus absorption isothermal well accorded with Langmuir line, and the absorption isothermal formula was obtained.
