【摘要】 采用树脂吸附法对我国东北地区3种水库水中的有机物进行了化学分级表征及三卤甲烷生成势的研究。结果表明,3种水库水中的溶解性有机物主要是亲水性有机酸(HPIA)和疏水中性物质(HPON),在有机物组分分布上具有一致性;HPON的THMFP值最高,而且占总DOC的百分比也很大,说明HPON是主要的三卤甲烷前体物;虽然各水库水中三卤甲烷生成活性最高的组分不相同,但疏水性有机物的三卤甲烷生成活性均高于亲水性有机物的;从3种水库水的有机物组分特征可知,虽然各水库水的水质有一定差异,但它们的三卤甲烷前体物特征具有一致性。更多还原

【Abstract】 The resin adsorption process was used for chemical fractionation of organic matters and THMFP characterization in water from three reservoirs in northern China.The results indicate that hydrophilic acid(HPIA) and hydrophobic neutral(HPON) are main parts of dissolved organic matters in water from three reservoirs,and they are consistent in the distribution of organic components.The THMFP of HPON is the highest,and it accounts for a large percentage of total DOC,so it is major trihalomethane precursor.Although the fractions of the highest specific THMFP in water from three reservoirs are different,the specific THMFP of hydrophobic organic matter is higher than that of hydrophilic organic matter.By comparing the characteristics of the organic components in water from three reservoirs,it is concluded that although the quality of water from three reservoirs is different,the characteristics of the trihalomethane precursors are consistent.更多还原
