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。
Abstract
[ 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 pollu-tion 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.
