采矿工业废水处理方法研究

Research on Treatment Technology for Mining Industry

指出了我国是一个矿业大国,但水资源相对匮乏。然而在采矿过程中,水资源通常有着广泛的用途,水资源的合理利用对于可持续性的采矿工业是极其重要的因素。采矿过程、相关的废水和场地排水,对于整体的自然环境,尤其是水资源会造成影响。因此,采矿工业有必要采取减轻废水排放对于环境污染的措施。针对采矿工业的发展、区域水资源供需,以及生态保护之间的矛盾,结合在加拿大纽芬兰与拉布拉多省镍矿区的实地考察,整理了现有研究成果和资料,着重对于采矿工业水资源利用及污水处理两方面进行了分析,为建设生态环保的矿区提出了合理化建议。

China is a large mining country with relatively scarce water resources. However, water resources have a wide range of uses in mining process, such as, mining metal ore, metal recovery, and dust control, etc. Therefore, the rational use of water resources is an extremely important factor for sustainable mining. Mining processes, associated waste water and site drainage will affect the overall natural environment, especially water resources. Therefore, it is necessary to take measures to reduce the waste water discharge for mining industry. Regarding the contradiction among the development of mining industry, the supply and demand of regional water resources and the ecological protection, this paper analyzes the existing research results after the case study of the nickel mining area in Newfoundland and Labrador, Canada. Focusing on the water resources utilization and sewage treatment, rational proposals have been put forward for the construction of eco--friendly mining.
