贵州大厂锑矿区水文地球化学特征及污染来源分析
Analysis of hydrogeochemical characteristics and pollution sources of Dachang antimony mining area in Guizhou Province
摘要
Abstract
It is of great significance to understand the hydrogeochemical characteristics and clarify the pollution characteristics and sources under the influence of antimony mining activities for the prevention and treatment of groundwater pollution under the background of mining activities.In order to find out the water environment of Dachang antimony mine in Guizhou Province,based on the field sampling of surface water and groundwater,the hydrochemical analysis and isotopic testing methods were used to analyze the characteristics and types of water chemistry in the mine area,study the composition characteristics of sulfate and oxygen and sulfur isotopes in the mine acidic water,and analyze the pollution sources and the migration and transformation law of antimony in the water environment.The results show that the main pollutants in the surface water are Mn,Hg,Sb,SO42-,and the main pollutants in the groundwater are Mn,Sb,Al,Hg.The water environment is seriously pol-luted.According to the analysis of sulfur end element,the main pollution source of water environment comes from the leaching water of waste slag pile and the drainage of adit.The research results provide an important ref-erence for long-term dynamic monitoring of antimony pollution in soil and water,mining development activities and ecological environmental protection.关键词
