摘要
试验研究了三类改性滤料及涂铁改性石英砂对饮用水过滤去除微量磷的效果。结果表明,所有改性滤料对总磷的去除率均达到了80%以上,改性石英砂对总磷的去除率最高。对改性石英砂的试验表明,当pH为4.5~6.5时,总磷的去除率较高。进水总磷浓度越高,改性石英砂达到吸附饱和时间越短。
The removal efficiency of phosphorus in drinking water by modified filter media,especially iron oxide-coated sand has been studied.It is surveyed thoroughly in order to obtain the drinking water biological stability.The results show that TP(total phosphorus)removal rate is up to 80%by filtration that uses all kinds of modified filter media,and TP removal rate is the highest by iron oxide-coated sand.Removal efficiency of TP is higher when pH value is within 4.5 to 6.6.The higher influent water TP concentration is,the shorter the time of reaching adsorbing saturation occurs.
