摘　　要：为研究非常规水源补给对受纳水体有机质的影响,采用光谱学方法对洨河水体有机质进行分析。结果表明,补给水源对干流的含氮有机质贡献较大,同时控制着羧酸有机化合物的水解、羧酸盐的形成及烃基缔合等过程。洨河上游有机质以腐殖化程度强的大分子量的类胡敏酸物质为主,中下游水体受含氮素有机质污染。下游有机质组成的芳香碳环含量逐渐增加,但芳香环上脂肪链取代基逐渐减少。水体自净过程产生的相对简单的有机质,在河道中以芳香碳环为中心发生了聚合反应,形成了极难降解的高聚合度有机物。With the application of spectroscopy,Xiaohe River was selected to investigate the impact of unconventional water sources on receiving water organic matter.The results showed that supply water had a greater contribution to nitrogenous organic matter in main stream,at the same time it controlled the hydrolysis of carboxylic acid compounds,formation of carboxylic acid salt and hydrocarbon association,etc.Due to the infusion of supply water the upstream of Xiaohe River molecular weight of organic matter with the humification degree deep big kinds of humic-like substances,aromatic carbon content and alphatic chain as the main substitute group,and the downstream aromatic carbon ring of organic matter content increased gradually.But the substituents on the aromatic ring alphatic chain to reduce gradually,and Xiaohe in the middle and lower reaches of the river water polluted by containing nitrogen and organic.Due to the polymerization,with aromatic carbon ring as the center,occurred in small molecular organic acids and alkyl compounds which formed in water purification process,high polymer organic compounds with extremely difficult degradation of the ultimate structure was formed.
