河池市龙滩水库水质及富营养化分析

Water quality and eutrophication analysis of Longtan Reservoir in Hechi City

为掌握河池市境内龙滩水库水质及富营养化状况,收集了2020年4月和2020年10月龙滩水库水质监测成果等数据,对相关水质参数和富营养化状况进行分析评价。结果表明,在所监测的项目中龙滩水库总氮项目超标,其余水质监测项目均优于地表水III类水标准要求。龙滩水库汛期水质劣于非汛期水质,富营养状况在汛期和非汛期均达标为中营养,应继续加强日常水质监督管理,以保持库区水质长久健康。

In order to understand the water quality and eutrophication status of Longtan Reservoir in Hechi City,the water quality monitoring data of Longtan Reservoir in April 2020 and October 2020 were collected;relevant water quality parameters and eutrophication status were analyzed.The results of analysis demonstrate the total nitrogen of Longtan Reservoir exceeded the standard,and the other water quality monitoring items were better than the require⁃ments of specification for Class III surface water.The water quality of Longtan Reservoir in flood season was worse than that in the non-flood season,and the eutrophication status reached the mid-grade standard in both flood sea⁃son and non-flood season.It is of great importance to continue to strengthen the daily water quality supervision and management to maintain the long-term health of the water quality in the reservoir area.
