中文摘要： 饮用水中的含氮有机化合物与含氮消毒副产物（N-DBPs）是目前水处理领域所关注的热点问题。我国水体富营养化问题严重，藻类生长旺盛，藻类代谢产物中含有较多的有机氮物质，被认为是N-DBPs的重要前体物。本研究以高藻饮用水源水为对象，研究水华藻种在正常生长和突发逆境环境情况下所释放的N-DBPs前体物的水平、结构和规律，着重研究典型水处理预氧化技术在高藻水处理过程中，对藻类有机物中的N-DBPs前体物的转化、控制规律。本研究将明确高藻水中典型N-DBPs前体物结构性质及产生规律，获悉高藻水预处理过程中N-DBPs前体物的转化规律。本研究可为高藻饮用水源水的处理及风险评估提供一定的理论支持。

英文摘要： Dissolved Organic Nitrogen (DON) and nitrogenous disinfection byproducts (N-DBPs) are becoming one of the hottest issues in drinking water field. Water eutrophication is a growing problem in China, while algae thrives in the eutrophic water. The metabolic substances of the algae contain a wide range of organic nitrogen compounds, which are considered to be important precursors of some N-DBPs. This study tries to assess the N-DBPs precursors in algae containing water. The aims of this work are to investigate the concentrations, molecular structures and variations of N-DBPs precursors released by algae during its growth in suitable and hostile environments, and access the variation rule of the N-DBPs precursors in pre-oxidation treatment of the algae containing water. The study will reveal the molecular structure of the typical N-DBPs precursors in algae containing water and obtain the variation rule of the N-DBPs precursors in pre-treatment processes. This study can provide a theoretical foundation for algae containing water treatment and its risk assessment.
