摘　　要：[目的]研究宿州市重污染河流奎河宿州段的污染源头和环境背景值。[方法]对河水进行总氮、总磷分析测试,并进行密度曲线图分析、频率直方图分析和Q聚类分析。利用正态法获取奎河总氮、总磷的环境背景值。[结果]奎河宿州段河水污染严重,受到人为因素污染程度大,污染源主要为工业废水、生活污水和农业污水。总氮环境背景值为0~6.66 mg/L,总磷环境背景值为0~0.84 mg/L。[结论]该研究可为奎河治理标准提供科学依据。[Objective] To research the pollution sources and environmental background values of heavy polluted river in Suzhou section of Kuihe River in Suzhou City of Anhui Province. [Method] Total nitrogen（ TN）,total phosphorus（ TP） in river were detected and analyzed.After the analysis of density curve,frequency histogram and Q cluster,environmental background values of TN and TP were obtained in Kuihe River by normal method. [Result]Suzhou section of Kuihe River was heavily polluted mainly due to the pollution of human factors. The pollution sources were mainly industrial waste,domestic sewage and agricultural wastewater. The environmental background values of TN and TP were 0- 6. 66 and 0- 0. 84 mg / L,respectively. [Conclusion] This research provides scientific references for the administrative standard of Kuihe River.
