1、前言
近年来，随着原水水质污染的加剧和高标准供水的需求，传统的净水处理工艺已经不能满足实际需要，传统工艺对微量有机物的处理不能达到理想的去除效果，而该类污染物却对人类健康存在威胁。饮用水的常规处理工艺主要目的是去除水中浊度、非溶解性有机物以及保证饮水的微生物安全,但对有机物、新型污染物、消毒副产物等物质的去除能力非常有限。当水源遭受污染又或对饮水水质有更高要求时,则需要对饮用水进行深度处理。活性炭是饮用水和废水处理中使用最广泛的吸附剂之一,对降低饮用水中有机物、消毒副产物、臭味物质等的含量有较好的效果,特别是针对原水机污染较严重的地区，臭氧-生物活性炭深度处理工艺是使用最为广泛的技术之一[1]。活性炭吸附对多种有机污染物处理优势明显，在活性炭吸附处理前设置臭氧氧化工艺可有效降低活性炭负荷，大大提升了水厂水质净化能力,有效改善了出厂水水质,具有较大的推广应用价值，因此更是净水深度处理的研究热点[2]。
