珊溪水库库区及入库支流水体紫外光谱特征分析研究

珊溪水库是温州地区的重要饮用水源地之一。在“五水共治”时代背景下，“保供水”特别是确保我市饮用水源安全是“五水共治”的组成部分之一。本文采用紫外光谱特征分析法评估珊溪水库主库区及主要入库支流考核断面水环境质量状况。分析结果表明：从黄坦坑、李井坑等监测站位的紫外特征吸收峰SUVA254分析二者污染较重，有机质芳化度、分子量和腐殖化水平相对较大。库区胡敏酸含量比富里酸含量大，支流天然水溶解性有机质( DOM)有机物分子缩合度高，腐殖化程度从支流到水库逐渐增大。

Water UV Spectrum Characteristics in Shanxi Reservoir and Its Tributaries

Shanxi reservoir is one of the most important drinking water source in Wenzhou. To guarantee water supply, espe-cially protecting drinking water reservoir of Wenzhou, is one of the components of“Five Water Governance”. This paper evalua-ted water quality of the main reservoir and its tributaries of Shanxi Reservoir by applying the method of ultraviolet spectrum charac-teristic analysis. The results showed that from SUVA254 analysis of monitoring stations such as Huangtankeng and Lijingkeng, both monitoring stations pollution was heavier and aromatic degree of organic matter, molecular weight and the level of humification was higher than the others. The humus acid content was larger than the fulvic acid. Organic molecular condensation degree of natural dissolved organic matter( DOM) was high in tributaries and the degree of humification increased gradually from tributaries to the main reservoir.
