| 摘 要： | 研究了水体中不同腐殖酸含量和过量ClO2充分反应的过程,探讨了ClO2消耗量及TOC、CODMn、UV254、UV410值的变化与腐殖酸起始含量之间的关系,结果表明:该腐殖酸水样的ClO2最大需求量为2.19 mg/mgTOC,ClO2剩余量和余氯的变化规律相似;腐殖酸水样的TOC和CODMn平均降低15%和19%,UV254和UV410去除率达到21%、49%,ClO2可以有效降低腐殖酸的THMs形成潜能和水体色度.

| Abstract: | For the reaction system between humic acid and enough ClO2 in water samples, the changes of residual ClO2, TOC, UV254, UV410 and CODMn under different conditions were investigated. The results showed that the maximum demand of ClO2 is 2.19 nag/ mgTOC, the change tendency of residual ClO2 was similar to that in the situation of Cl2 as disinfection reagent, TOC and CODMn of humic acid decreased 15 % and 19% respectively, 21% of UV254 and 49% of UV410 were removed under the experimental conditions. It was also demonstrated that ClO2 had an effective affect to reduce THMs formation potential of humic acid and color of water samples. |
