| 摘 要： | 文章研究了185nm紫外光/氧化协同降解水体中微量三氯甲烷的降解情况,考察了溶液浓度、光解时间、溶液pH值以及加入氧化剂等对降解三氯甲烷的影响,研究结果表明,CHCl3的脱氯基本是由185nm紫外光引起;其脱氯率几乎不受pH值的影响;在近中性条件下,5mg.L-1的三氯甲烷水溶液的CODMn去除率、脱氯率均与光解时间呈指数上升;光解5min后,CODMn去除率可达50%左右,脱氯率则小于30%;CHCl3的解离主要是185nm光子的作用,而与其它氧化性物质无关。

| Abstract: | The degradation effect of low concentration of chloroform in water is studied by using 185 nm UV light and oxidation technique.The influence of concent-ration of chloroform,the solutions pH value,the treating time,the oxidants and the appropriate technical parameter is preliminary discussed.The results show that dissociation of CHCl3 in water is mainly due to 185 nm photons and has nothing to do with other oxidizing substances.The efficiency of dechlorination and the removal efficiency of CODMn as a functio... |
