摘　　要：针对饮用水中藻毒素污染问题,本文对超滤膜(UF)、粉状活性炭(PAC)及其组合工艺去除藻毒素(MCs)的效果和特性进行了研究。结果表明,单独的超滤膜工艺对水体中溶解性藻毒素的去除率较低,一般低于5%。单独的粉末活性炭吸附技术在投加量高于20mg·L-1时对MCs的去除效率较高,可达82.16%;粉末活性炭与超滤联用工艺在PAC投加量为20mg·L-1时,产水中未检测出微囊藻毒素。该组合工艺运行稳定,可有效减缓膜污染。Aiming at the pollution of microcystins in drinking water,the individual and integrated process of ultrafiltration（UF） and powdered actived carbon（PAC） were systematically studied on the removal characteristics for microcystins in this paper.Results showed that the removal rate of individual UF membrane for the soluble MCs was lower than 20%,while the PAC adsorption was effective to remove MCs at a dosage of 20 mg·L^-1 or higher,the removal rate could attain as high as 82.16%;MCs was failed to detected after the treatment of integrated process of PAC and UF at a dosage of 15 mg·L^-1,which operated stably and alleviated membrane fouling effectively.
