矿井疏干水利用与处理技术研究

A Study on Mine Drained Water Utilization and Treatment Technologies

长期以来,矿井疏干水一直被视作水害加以预防和治理。矿井疏干水的排放不仅大量浪费宝贵的地下水资源,而且也造成了一系列严重的环境污染问题。对矿井水进行处理并加以利用,不但可防止水资源流失,避免对水环境造成污染,而且对于缓解矿区供水不足、改善矿区生态环境、最大限度地满足生产和生活需要具有重要意义。根据矿井水所含污染物的特征,将矿井水分为洁净、高悬浮物、酸性、高矿物和含特殊污染物5种,并对各类水的特征及处理技术进行了较为详细的介绍。最后指出,矿井疏干水在回收利用时,应根据用途按分质分用、经济方便的原则,其利用方面主要是井下用水、煤矿工业用水、生活用水、农业灌溉用水和生态用水等。

For a long time,the mine drained water was seen as a kind of noxious substance need to be prevented and managed.The discharge of mine drained water is not only wasted abundant and valuable underground water resources,but also made a series of severe environment pollution issues.Treatment and utilization of mine water,not only can prevent water resource to be run off,avoid pollution on water environment,and furthermore have significances on moderating mine area insufficient water supply,improving ecological environment,farthest satisfying production and living needs.According to pollutant characteristics the mine water contained,participate the mine water into 5 kinds of clean,high suspended solid,acidic,high mineral and special pollutant and introduced each kind water characteristics and treatment technology in detail.Finally point out: when reclaiming and utilizing mine drained water,should according to the principles of particular quality for particular purpose,economic and advantageous.Its utilization fields have mainly underground,coalmine production,living,agricultural irrigation and in ecological domain.
