摘要
随着我国煤炭开采规模的扩大、开采深度的增加以及开采区域的西延,煤矿矿井水水量逐年增多,水质也呈现出复杂多样化的特点。与此同时,我国生态环保要求日益严格,煤矿区排水水质标准也大幅提高,给煤矿矿井水处理和矿用絮凝剂的开发与使用提出了更高的要求。系统梳理了絮凝剂的研究进展,阐述了其在煤矿矿井水处理中的应用与挑战,并针对应用中的问题提出了未来的研发方向。为了满足新需求、适应新形势,新型矿用絮凝剂未来会向多功能、高效率、低成本及绿色环保的方向发展,并且优先考虑絮凝性能和环保要求,在满足处理水质需求和效率最大化的基础上,对其成本进行有效控制。
With the expansion of coal mining scale,the increase of mining depth,and the westward extension of mining area in China,the quantity of coal mine water has been increasing year by year,and the quality has also been complex.Meanwhile,China’s ecological and environmental protection requirements have become increasingly stringent,and the water quality standards of coal mining areas have also been greatly improved,which puts forward higher requirements for coal mine water treatment and the development of mining flocculants.The research progress of flocculants was summarized systematically.The applications and challenges of flocculants in various mine water treatment were expounded.The future research and development direction were proposed based on the challenges.In the future,new flocculants for mine water treatment will be developed with the aims of multi-function,high efficiency,low cost and green environmental protection.And the priority is high performance and environmental protection,followed by effective cost control based on satisfying the demands of treated water quality while optimizing efficiency.
