| 摘 要： | 以城市污水厂二级出水为研究对象,采用大孔吸附树脂将污水中溶解性有机物分离成亲水性物质、疏水酸性物质、疏水中性物质和疏水碱性物质4个组分,分析了各组分的有机物特性、三维荧光光谱特征和氯消毒副产物生成潜能.结果表明,亲水性物质和疏水酸性物质分别占水样中溶解性有机碳的33%和30%,其中亲水性物质相对含有较多的生物源腐殖质类物质,疏水酸性物质相对含有更多的芳香族蛋白质和溶解性微生物代谢产物类物质.氯消毒后,亲水性物质的三卤甲烷生成潜能分别为630.4μg.L-1,占污水三卤甲烷生成潜能的73.7%.亲水性物质和疏水酸性物质的卤乙酸生成潜能分别为644.6μg.L-1和123.2μg.L-1,是污水氯消毒副产物的主要前体物.
