粉末活性炭与超滤膜联用去除饮用水中污染物的研究

介绍了粉末活性炭-淹没式中空纤维膜过滤装置联用（PAC-IHFMS）去除饮用水中污染物的试验研究，并与只用淹没式中空纤维膜过滤装置的处理效果进行了比较。粉末活性炭直接浸入装有中空纤维膜的反应器中，浓度为250mg/L，与水接触时间为40min，超滤膜渗透通量为12L/h，研究结果表明，粉末活性炭的加入，可以增强淹没式中空纤维膜过滤装置对高锰酸盐指数和NH4^ -N的去除效果，但对UV254的去除效果影响汪大，对浊度和细菌总数的去除没有帮助，只用淹没式中空纤维膜过滤装置就可以有良好的除浊和消毒效果。研究结果还表明，粉末活性炭的加入，可以减轻膜污染，对维持超滤膜高比流量起到重要作用。

Removal of pollutants by combined powdered activated carbon and ultrafiltration membrane

Studies the removal of pollutants from drinking water with combined PAC-Immersed hol- low fiber membrane system and compares the efficiencies of removal of pollutants before and after the immersion of PAC in the IHFMS system which contain hollow fiber membrane, and points out that at the concentration is 250mg/L, PAC takes 40 min to get in contact with water, and the ultrafiltration membrane flux is 12L/h, and concludes from test results that the addition of PAC im- proves the removal of CODMn and NH+4-N in IHFMS but does not change the removal of UV 254 too much, and concludes from test results that the addition of PAC can effectively reduce the membrane resistance and maintain a high flux for a long period of time.
