活性炭—纳滤膜净化受污染地下水的试验研究

Study on Activated Carbon-Nanofiltration Membrane for Contaminated Groundwater Purification

将活性炭-纳滤膜技术应用于南方地区浅层地下水的净化中,该工艺能有效去除地下水中的有机及无机污染物。对有机物的去除率在80%以上,对电导率、总硬度的去除率也分别达到80%和90%,对其它污染物也有较高的去除率。研究成果为以地下水为水源的小城镇地区供水提供了新思路,拓宽了纳滤膜净水技术的应用领域。

Activated carbon（AC） -nanofiltration （NF） process was used to purify contaminated shallow groundwater of the Southern area of our country. The experiment has showed that it is feasible to combine AC and NF to obtain high quality drinking water from groundwater,the removal of organic pollutant was over 80% ,and conductivity over 80% ,and total hardness over 90%. The study offers small towns with groudwater as their headwater and a new way for water supply. And it expands application ranges of nanofiltration membrane as well.
