本文聚焦矿井水处理工艺研究，针对铁离子去除难题，结合TRIZ理论物质场模型，采用曝气+混凝+锰砂过滤三法结合，有效去除铁离子，并针对矿井污水悬浮物去除问题，结合TRIZ理论冲突解决原理，采用高效澄清一体化设备，有效提升絮凝效果。基于TRIZ理论进化原理，形成矿井水综合处理工艺流程，并基于矿井水处理站进行技术实践。结果表明，悬浮物在经过锰砂过滤器以及活性炭过滤器后全部去除，铁离子在经过超滤加消毒后全部去除，满足矿井水处理要求。处理站出水可达到地表水Ⅲ类标准，可回用、可排放。

This paper focused on the research of mine water treatment process. Aiming at the problem of iron ion removal, combined with the material field model of TRIZ theory, the three methods of aeration + coagulation + manganese sand filtration were combined to effectively remove iron ions. In view of the removal of suspended solids in mine sewage, combined with the conflict resolution principle of TRIZ theory, the efficient clarification integrated equipment was adopted to effectively improve the flocculation effect. Based on the evolution principle of TRIZ theory, the process flow of mine water comprehensive treatment was formed, and the technical practice was carried out based on the mine water treatment station. The results showed that the suspended solids were completely removed after manganese sand filter and activated carbon filter, and the iron ions were completely removed after ultrafiltration and disinfection, which fully met the requirements of mine water treatment. The effluent of the treatment station could meet the Class III standard of surface water, which could be reused and discharged.
