摘要
采用纳滤膜对某市自来水进行深度处理试验,研究了纳滤对自来水中有机物及离子等的去除效果。结果表明,采用一级纳滤工艺,在回收率为70%的情况下,能有效去除自来水中的有机物、离子、内分泌干扰物和细菌等。对CODMn、浊度、Cr6+和阿特拉津的平均去除率分别为81.06%,85.47%,77.20%和83.90%;对总硬度和阴离子的去除率保持在一个适中的水平;出水中未检测出细菌。
A kind of advanced treatment for drinking water with nanofiltration(NF) membrane was conducted,and its removal efficiency of organic matters and ion,etc.with nanofiltration was investigated.The results showed that organic matters,ion,endocrine disruptors and bacteria could be removed effectively with first stage NF under the water recovery rate of 70%.The removal rates of CODMn,turbidity,Cr6+ and Atrazine were 81.06%,85.47%,77.20% and 83.90% respectively.The removal rates of hardness and anion could be kept in satisfiable levels,and no bacteria were detected in the treated water.
