| 摘 要： | 利用树脂分离技术将水中天然有机物分为腐殖酸(HA)、富里酸(FA)、亲水酸(HPIA)和其它亲水物质(HPI-NA)等4部分,研究了高锰酸钾对不同有机组分卤代活性的影响.结果表明,高锰酸钾增加了腐殖酸和其它亲水物质加氯的卤代活性,降低了富里酸和亲水酸的卤代活性,如投加0.75 mg/L高锰酸钾时,腐殖酸和其它亲水物质的卤代活性增加了39.3%和13.8%,而富里酸和亲水酸卤代活性降低了33.6%和46.9%;通过对SUVA的考察可知,高锰酸钾增加了腐殖酸和其它亲水物质的碳碳不饱和双键的含量,使其卤代活性增

| Abstract: | Effects of potassium permanganate(PP) oxidation on natural organic matter(NOM) chlorination activity was studied in the article.Natural organic matter was separated into humic acid(HA),fulvic acid(FA),hydrophilic acid(HPIA) and non-hydrophilic acid(HPI-NA)fraction four fractions by XAD resin adsorption technique.Potassium permanganate oxidation alone increased HA and HPIA chlorination activity and decrease that of FA and HPI-NA.The chlorination activity of HA and HPIA were increased by 39.3% and 13.8% by 0.75 mg/L potassium permanganate,but the chlorination activity of FA and HPI-NA were decreased by 33.6% and 46.9%. SUVA results showed that potassium permanganate increase FA and HPIA unsaturated band contents,and decreased that of FA and HPI-NA.Compared with coagulation, potassium permanganate combined with coagulation can decrease the trihalomethanes of HA,FA,HPIA and HPI-NA by 9.1,15.7,7.2 and 14.7 per cent compared with that of coagulation alone. |
