摘要
针对珠海市多水源的特点,选定三个不同水源进行测定分析,以确定其有机物分子量分布特性。通过一个水文年的研究结果表明:珠海市微污染水源水的共同特性是大分子量(>10000Dalton)和小分子量(<1000Dalton)的有机物占有机物总量的绝大多数,而处于中间范围分布的有机物相对较少。利用GC-MS联机试验分析发现传统净水工艺很难有效去除此类微污染水中的溶解性有机物。
Three kinds of source water in Zhuhai were analyzed to determine the distribution cha-racteristics of molecular weight of organic matters. After a whole hydrological year’s research, it showed that high-molecular-weight (>10 000 Dalton) and low-molecular-weight (<1 000 Dalton) organic matters accounted the main part of total organic matter distribution, and the middle range’s distribution was relatively low in slightly-polluted source water of Zhuhai. GC-MS combination test showed that conventional water treatment process could not remove dissolved organic matters in this kind of slightly-polluted water effectively.
