| 摘 要： | 在将有机物分级和分类的基础上,研究了氯胺消毒对不同类有机物生成消毒副产物的影响.试验结果表明:对于亲水性和强疏水性有机物,氯胺消毒主要减少溴代三卤甲烷(CHCl_2 Br和CHClBr_2)的生成;对于弱疏水性有机物,氯胺消毒主要减少二溴乙酸(DBAA)和三氯甲烷(CHCl_3)的生成;氯胺消毒能使分子量小于10 ku的有机物生成三卤甲烷(THMs)和卤乙酸(HAAs)的量明显降低,并且随着有机物分子量的升高,氯胺消毒的影响效果有一定程度的减弱.

| Abstract: | A study was made of the influence of chloramination on DBPs formation from different organics based on the grading and clssification of organics.The experimental results show that the formation of CHCl2Br and CHClBr2 are restricted by chloramine disinfection for the hydrophilieity and strong hydrophobicity organics.For the weak hydrophobicity organics,formation of DBAA and CHCl3 is affected.Chloramine disinfection reduces the THMs and HAAs formation from the organics whose molecularities are less than 10 ku,and the influence is weakened to some certain extent with the increase of molecular weight in chloramination. |

| Keywords: | chloramine disinfection products hydrophilieity hydrophobicity molecular weight |
