摘　　要：近年来,随着我国西部煤炭开采规模和开采深度的逐年增加,矿井水中的氟化物含量有明显升高,给煤炭行业绿色开发带来新的技术难题。成熟高效的高氟矿井水处理方案成为目前矿井水处理的主要发展趋势。首先介绍了常用的除氟工艺,分析各工艺的特点;然后以内蒙古鄂尔多斯某煤矿1和某煤矿2的矿井水除氟项目为例,详细阐述了离子交换法和滤料吸附法处理高含氟矿井水的工艺流程、主要设备和系统运行药剂费,为高含氟矿井水处理设计人员提供参考和借鉴。运行数据表明,离子交换法和滤料吸附法均可实现产水氟离子≤1 mg/L的要求,且滤料吸附法的吨水药剂运行费远低于离子交换法的吨水运行费,约低40%。实际应用时可根据具体情况进行选用,同时分析2种除氟工艺的共性及互补性,提出优化建议。In recent years,with the increasing scale and depth of coal mining in western China,the fluoride content in mine water has significantly increased,posing new technical challenges for the green development of the coal industry.Mature and efficient high fluoride mine water treatment solutions have become the main development trend in current mine water treatment.First introduces commonly used defluorination processes and analyzes the characteristics of each process.Then,taking the defluorination projects of coal mine 1 and coal mine 2 in Ordos,Inner Mongolia as an example,the process flow,main equipment,and system operation reagent costs of ion exchange method and filter adsorption method for treating high fluoride mine water were elaborated in detail,providing reference and inspiration for high fluoride mine water treatment designers.The operational data shows that both ion exchange method and filter adsorption method can achieve the requirement of producing fluoride ions≤1 mg/L in water,and the operating cost per ton of water for filter adsorption method is much lower than that of ion exchange method,about 40%lower.In practical applications,the selection can be based on specific circumstances,while analyzing the commonalities and complementarity of the two defluorination processes,and proposing optimization suggestions.
