摘要:
山西某煤矿缺少矿井水处理设施，故需新建矿井水处理站，其设计处理规模为200 m3/h。煤矿酸性矿井水处理采用“预沉调节池+曝气氧化反应池+混凝反应除氟高效沉淀池+除铁除锰滤池+复合滤料生物滤池+超滤”组合工艺，有效去除矿井水中SS、COD、BOD5、氨氮、铁、锰、氟、石油类等污染物，出水水质（TN除外）达到《地表水环境质量标准》（GB 3838—2002）Ⅲ类标准，尾水回用或排放。该组合工艺运行成本约1.574元/m3，其中高效除氟药剂费占41.93%，高效除氟药剂用于矿井水中低浓度氟的去除，克服了传统除氟技术的不足，且具备运行管理简单的优势。此外，超滤系统对矿井水出水水质稳定具有重要保障作用。
Abstract:
A coal mine in Shanxi Province currently lacks adequate mine water treatment facilities. Therefore, it is necessary to construct a new mine water treatment station with a designed treatment capacity of 200 m3/h. The treatment of acidic mine water in the coal mine employed a combined process consisting of pre-sedimentation regulating tank, aeration oxidation reaction tank, coagulation and fluoride removal high?efficiency sedimentation tank, iron and manganese removal filter, dual media biological filter, and ultrafiltration. This integrated approach effectively removed key pollutants such as SS, COD, BOD5, ammonia nitrogen, iron, manganese, fluoride, and petroleum from the mine water. The monitoring indicators of the effluent (excluding TN) met the quasi-class Ⅲ limit specified in Environmental Quality Standards for Surface Water (GB 3838-2002). The resulting tailwater can either be reused or safely discharged. The operating cost was approximately 1.574 yuan/m3, with high-efficiency defluoridation reagent accounting for 41.93% of the total. These reagents were specifically employed to remove low-concentration fluoride from the mine water, effectively addressing the limitations of traditional fluoride removal methods while offering the advantages of straightforward operation and ease of management. Furthermore, the ultra-filtration system played a critical role in maintaining the consistent quality of treated effluent.
