摘要
针对某煤矿高氟矿井水,在已有"高锰酸钾预氧化+机械混凝+迷宫斜管沉淀"工艺基础上新增"调酸+高速浅层砂滤+碳基磷灰石"矿井水深度除氟工艺;利用氯化钙对高氟再生废液中氟离子进行固化,并通过"混凝+沉淀+压滤"工序实现氟化物从液相向固相转化,完成氟化物从矿井水中去除.详细介绍和总结了碳基磷灰石在矿井水除氟中的设计参数及调试经验,可为高氟矿井水治理提供参考与借鉴.
Abstract
Based on the existing treatment process of"potassium permanganate pre-oxidation+mechanical coagulation+labyrinth inclined pipe precipitation","acid adjustment+high-speed shallow sand filter+carbon-apatite"was selected as the depth de-fluorination process for high fluoride mine water in a coal mine.Meanwhile,fluoride ions in high-fluorine regeneration waste water were solidified by adding calcium chloride.Besides,fluoride ions were converted from liquid phase to solid phase by"coagulation+precipitation+pressure filtration"and completely removed from mine water.The design parameters and commissioning experience for the application of carbon-apatite in the treatment of high fluoride mine water were detailed and summarized,which could be used as references and guidance for the treatment of high fluoride mine water.
