摘　　要：[目的]研究不同客水对南淝河水体富营养化的影响及其降解特征。[方法]以典型城市河流南淝河为研究对象,调查受不同排口影响下南淝河水质特征,评价南淝河水体富营养化状态;并以初期雨水、道路径流和污水处理厂尾水为代表性客水来源,探明不同来源客水在客水土著微生物、光化学的作用下水质及溶解有机质组成的变化特征。[结果]南淝河水体总氮(TN)和总磷(TP)含量受污水处理厂尾水排放影响较大,且南淝河总体上处于富营养或超富营养状态,但叶绿素(Ch-a)含量和富营养化等级在受不同排口影响下的河段中却不存在明显差异;不同来源客水在土著微生物和光化学作用下,其TN和TP均有较大的削减,且溶解有机质(DOM)组成发生了明显的转化。[结论]该研究可为城市河流的综合整治,特别是入河污染物的削减技术提供新思路。[Objective]To study the effects of foreign water on trophic state for Nanfei River and its degradation characteristics. [Method]Taking typical city river Nanfeihe River as the research object, different discharge characteristics under the influence of Nanfeihe river water quality evaluation were investigated, eutrophication status of water body of Nanfei River was evaluated. The characteristics of water quality and dissolved organic matter in different source water were investigated by using the initial rainwater, road runoff and sewage treatment plant tail water as representative water source.[Result]The total nitrogen of Nanfeihe River water （TN） and total phosphorus （TP） contents of tail water from sewage treatment plant has great influence, and generally in the Nanfeihe River eutrophication or super eutrophication, but the chlorophyll （Ch-a） content and the eutrophication level in different outlet under the influence of the river does not exist the obvious difference. The TN and TP of the water from different sources were greatly reduced under the influence of indigenous microorganisms and photochemistry, and the transformation of dissolved organic matter （DOM） was obvious. [Conclusion]The study can provide new ideas for the comprehensive regulation of urban rivers, especially for the reduction of pollutants into rivers.
