摘要:
在连续对黄浦江原水中各水质指标一年间含量及变化特征调研的基础上,利用分子量分布和GC/MS联机检测等手段,深入开展了有机物组成和特性的研究.结果表明:黄浦江原水水质基本为Ⅲ~Ⅳ类,有机污染问题突出,并受季节影响明显,属微污染水源水; 黄浦江原水中有机物含量较高、种类繁多,BDOC/DOC值在21%~27%之间,可生物降解性不好; 黄浦江原水中有机物构成以低分子量有机物为主,分子量小于1×103 Da的低分子量有机物占DOC总量的46%左右,具有明显的湖泊水质特征,并受到流域周边工业和生活污染源排放的影响.要全面提高黄浦江水源水厂的有机物去除效能、改善出厂水水质,必需采用能有效去除小分子量有机物的强化与深度净水工艺.
Abstract:
Concentrations and changes of quality indexes in raw water from Huangpu River have been investigated for one year. Characteristics and compositions of organics were studied by determination of molecular weight(MW)distribution and GC/MS. Results show that the quality of raw water from Huangpu River can be referred to level Ⅲ to Ⅳ(by national environmental quality standard of surface water), defiled by organics and affected by season obviously, and belongs to micro-polluted raw water. The organic matter content in the raw water is high, with various species and poor biodegradability(BDOC/DOC ranging from 21% to 27%). The majority of organic matters in the raw water are with low MW. The fraction of low MC organics(<1×103Da)corresponds to 46% of the total DOC. Characteristics of raw water from Huangpu River are in accordance with lake water and influenced by waste water. In order to decrease organics level to improve quality of finished water, the enhanced and advanced processes which can reduce low MW organics effectively must be employed.
