攀枝花矿区河流环境中钒的现状研究

Research Status of Vanadium in Fluvial Environment of Panzhihua Mining Area

攀枝花是典型的工矿业城市,有着完备的钒产业体系。由于近几十年来钒矿石的开采,当地钒污染已成为特有的环境问题。此外,攀枝花是长江上游第一大工业城市,长期以来的钒排放势必会对长江下游产生影响。因此,流经矿区的金沙江是研究水体中钒的分布与行为的理想场所。本文总结了前人的研究,分析了金沙江攀枝花段河流多相介质(溶解相、悬浮颗粒物、沉积物)中钒的来源、分布以及归趋,为之后的研究提供思路。

Panzhihua is a typical industrial and mining city in southwest China,with a complete vanadium industry system.Due to the exploitation of vanadium ores in recent decades,vanadium pollution has become a particular environmental problem.In addition,Panzhihua is the largest industrial city in the upper reaches of the Yangtze River.The long-term vanadium emissions are bound to have an impact on the lower reaches of the Yangtze River.Therefore,the Jinsha River fl owing through the mining area is ideal for studying the distribution and behavior of vanadium in water.This paper summarizes the previous studies,the source,distribution,and fate of vanadium in multiphase media(dissolved phase,suspended particulate matter,sediment)of the Jinsha River in the Panzhihua section and provides some ideas for future research.
