UV-微 O_3 法去除饮用水中 CCl_4 的研究

Study on the Treatment of Tetrachloromethane in Drinking Water with UV slight O 3 Technology

研究了以紫外－微臭氧为主体的光化学激发氧化技术的最佳运行参数，用该工艺处理饮用水中微量有机优先污染物。研究结果表明：紫外－微臭氧工艺对ＣＣｌ４－水中常见有机优先污染物有令人满意的去除效果，经２小时处理后，去除率可达９０％。紫外－微臭氧工艺对饮用水的深度处理能力接近于紫外－臭氧工艺，设备方便，投资少，是一种很有前途的饮用水净化工艺。

In this paper,the most advantageous operational data about the photochemical oxidation techno logy of mainly ultraviolet radiation with microozone was studied,organic micropollutants in the drinking water were treated with this technology.The results showed that process of UV microozone could successfully oxidize prior pollutants of CCl 4.after 2 hours treatment,the removal efficiency of CCl 4 in drinking water reached more than 90%,it showed that this drinking water treatment technology was very powerful.All the results showed that the UV microozone technology was about as powerful as UV O 3 technology in drinking water treatment ability,and the UV microozone technology only needs simple equipment and less investment,It was an advanced drinking water purification technology.
