摘要
介绍了饮用水中有机物的组成及其去除评价指标,并指出了各类有机污染物对饮用水水质的影响。重点探讨了水中各类有机污染物的去除方法:强化混凝、颗粒活性碳、膜过滤、光催化氧化、臭氧-生物活性炭及生物预处理技术等。最后总结了各种处理方法的优缺点,为选择合适的去除有机污染物工艺提供参考。
The types of organic constituents and the appraisal indexes of removal were introduced in this paper. At the same time the impacts of every type of organic pollutants on drinking water quality were pointed out. Then, the main treatment methods of each species of organic pollutants in drinking water treatment which including enhance coagulation, granule activate carbon, membrane separation process, photocatalytie oxidation, O3-BAC, biological pretreatment, etc. were mainly discussed. Finally, their merits and shortcomings were summarized for selection of treatment processes focused on organic pollutants.
