运用自动监测网络与实验室验证相结合的手段,通过测定湘江流域衡阳段干流与支流铊浓度,分析铊浓度与溶解氧含量、氨氮浓度及叶绿素 a浓度等水质指标的关系,进而对湘江流域衡阳段铊污染进行原因分析.结果表明,2021年 8 月上旬,湘江流域衡阳段干流铊污染的来源主要为多支流污染汇入.其中,松木下游断面铊污染极有可能来源于支流上游企业排放,江东水厂断面铊浓度异常的原因主要为溶解氧降低、死藻富集.该案例可为我国铊污染应急监测及污染原因分析提供借鉴.
Analysis of Thallium Pollution Causes in Hengyang Section of Xiangjiang River Basin Based on Automatic Monitoring Network
By measuring thallium concentration along the main stream and tributaries of Hengyang section of Xiangjiang River Basin,this study analyzed the correlation between thallium concentration and water quality indexes such as dissolved oxygen content,ammonia nitrogen concentration and chlorophyll a concentration,and then analyzed the causes of thallium pollution in Hengyang section of Xiangjiang River basin by means of automatic monitoring network and laboratory verification.The results showed that in early August 2021,the source of thallium pollution in the main stream of Hengyang section of the Xiangjiang River Basin was mainly the inflow of multiple tributaries.And the thallium pollution in the downstream of Songmu section was very likely to come from the discharge of enterprises in the tributary basins.The abnormal thallium concentration of Jiangdong Water Plant section was mainly caused by the decrease of dissolved oxygen and the enrichment of dead algae.This case can provide reference for the application of thallium pollution emergency monitoring and pollution traceability technology in China.
