紫外-微臭氧处理饮用水中有机优先污染物

Treatment of organic priority pollutants in drinking water by micro ozone oxidation combined with ultraviolet radiation

城市自来水水质下降，研究开发给水深度处理技术刻不容缓。本文采用新型紫外—微臭氧工艺处理自来水中常见的三氯甲烷、四氯化碳、邻－二氯苯、对－二氯苯、１，２，４－三氯苯和六氯苯等６种优先污染物。处理结果表明，与紫外—臭氧工艺相比，本项技术作为自来水深度净化手段，具有效果基本相等，设备大幅度简化，运行费用低廉，更易于推广的优点。

It is of urgency to develop advanced treatment techniques for drinking water because of quality decline of tap water in out country. This paper reports investigations of a new water treatment process of micro ozone oxidation combined with ultraviolet radiation (UV micro O 3).Satisfactory experimental results were achieved by using UV micro O 3 process to oxidize 6 organic priority pollutants in drinking water such as trihalomethan, carbon tetrachlorite, hexachlorobenzene,etc.As an advanced drinking water treatment technique, UV micro O 3 process has advantiges as follows: strong treatment efficiency, simple construction, low operation cost and good application feasiability.
