摘要
以水体中氟化物为研究对象,对大连市重要地表水环境氟化物进行了现状调查,以2018—2023年2月复州河西韭大桥断面和浮渡河西北窑断面氟化物进行年际对比,并对河流干流和支流进行采样监测,分析氟化物的主要来源、浓度变化及其分布特征。结果表明:温泉旅游企业废水排放是两断面氟化物升高的主要原因,氟化物含量枯水期高于其他水期。通过对氟化物污染防控对策的可行性研究,提出对策建议。
Taking fluoride in water bodies as the research object,a survey was conducted on the current situation of fluoride in important surface water environments in Dalian.An annual comparison was conducted between the Jiu Bridge section in the west of Fuzhou River and the Xibeiyao section of Fudu River from 2018 to the February of 2023.Sampling and monitoring were conducted on the main and tributaries of the river to analyze the main sources,concentration changes,and distribution characteristics of fluoride.The results show that the wastewater discharge from hot spring tourism enterprises is the main reason for the increase of fluoride in the two sections,and the fluoride content in the dry season is higher than that in other water periods.At the same time,through the feasibility study of fluoride pollution prevention and control measures,countermeasures and suggestions are proposed.
