摘　　要：针对鄂尔多斯市矿井水氟化物超标水质处理难题,在混凝沉淀阶段通过络合诱导除氟原理最大程度去除矿井水中氟化物浓度,通过调整加药量,氟化物最大去除率达到95%。再配合改性滤料过滤保障矿井水达到规定限值1 mg/L以下排放,该种工艺除氟运行成本约为1.79元/吨水,较本地区煤矿矿井水除氟成本降低40%左右,两种工艺结合具备工程应用条件,为非常规水源综合利用提供技术支撑。In order to solve the problem of treatment of excessive fluoride in mine water in Ordos City,the fluoride concentration in mine water was removed to the maximum extent through the principle of complexation-induced defluorination at the coagulation and precipitation stage.By adjusting the dosage,the maximum removal rate of fluoride reached 95%.Combined with modified filter material to ensure that the mine water reaches the prescribed limit value of 1 mg/L or less,the defluorination operation cost of this process is about 1.79 yuan/t,which is about 40%lower than the mine water defluorination cost in the region.The combination of the two processes has engineering application conditions,and can also provide technical support for the comprehensive utilization of unconventional water sources.
