我国煤矿矿井水氟污染现状及除氟技术研究

氟污染成为制约矿井水资源化利用的重要因素，分析了我国煤矿矿井水氟污染现状及含氟矿井水的水质特征。化学沉淀法、混凝沉淀法、离子交换—吸附法、电化学法和膜法是目前常用的除氟方法，通过对各种除氟方法的原理、处理效果和优缺点等进行对比发现，离子交换—吸附法较为成熟，在矿井水除氟工程中应用最为广泛。研究表明，开发高效、经济、安全、稳定的除氟材料与成套装备，是含氟矿井水资源化利用的重要途径。

Status quo of fluoride pollution of coal mine water in China and research on fluoride removal technology

Fluoride pollution has become one of important factors restricting utilization mine drainage water resources.The current situation of fluoride pollution of coal mines drainage water in China was summarized，and the characteristic of fluorine-containing mine drainage water was analyzed.Chemical precipitation，coagulation sedimentation，adsorption-ion exchange，electrochemical，membrane process were the main methods of defluoridation of water treatment applications.Comparisons of these methods were made in many aspects such as:defluoridation mechanisms，treatment effect，advantages and limitations.The result showed that adsorption-ion exchange technology was more mature and the most used in defluoridation of mine drainage water.The development of efficient，economical，safe，and stable defluorination materials and complete equipment was an important way to utilize fluorine-containing mine drainage water.
