| 摘 要： | 基于沙颍河流域的水环境污染研究，利用不同污染评价指数的计算方法，针对不同水期、不同干流、不同支流河段水体样本的重金属污染特征进行分析，对沙颍河流域水环境污染控制因素及迁移影响规律进行探究，旨在为沙颍河流域水环境污染防治提出具有针对性的理论依据。结果表明：沙颍河流域整体在枯水期存在轻度Mn、Mo污染现象，流域整体污染受控于上游支流颍河和支流北汝河的污染，其中支流颍河污染的主要控制因素为Mn,支流北汝河污染的主要控制因素为Mn和Mo。污染的主要来源为矿产和工业污废水的排放，自上游至下游河段顺水流迁移转化，而流域整体呈轻度污染，污染水平主要受到pH值、溶解氧(DO)、温度(T)的影响。

| Abstract: | Based on the study of water environmental pollution in the Shaying River basin, the heavy metal pollution characteristics of water samples in different water periods and in different reaches of the main river and the tributaries were analyzed by using the calculation methods of different pollution evaluation indexes, and the control factors of water environmental pollution and the influencing laws on their migration were discussed separately, to provide a theoretical basis for the prevention and control of water environmental pollution in Shaying River basin. The results showed that the overall pollution of The Shaying River basin was slightly polluted by Mn and Mo in the dry season. The overall pollution of the Shaying River basin was controlled by the pollution of the upper tributary Yinghe River and the tributary Beiru River. The main controlling factors of pollution of the Yinghe River and the Beiru River were Mn and Mo. The main source of pollution was the discharge of mineral and industrial sewage, which migrated and transformed downstream from the upper reaches to the lower reaches, presenting a mild pollution level of the whole basin. And the polution level was mainly affected by pH value, dissolved oxygen (DO) and temperature (T) value. |
