Hypersalinity water desalination treatment system and desalination method based on strip mine dump
The invention discloses a hypersalinity water desalination treatment system and desalination method based on a strip mine dump. Stripping materials of a strip mine and a wide site of the dump are utilized to construct a freeze-thaw cycle desalination system, and the freeze-thaw cycle desalination system is divided into a plurality of freeze-thaw sub-pools to improve the treatment capacity and arrangement flexibility of the system; the cold weather condition in winter in the northern area is fully utilized, high-salinity water is changed into ice with low salinity and water with high salinity, and the ice is further melted into fresh water through waste heat of a mining area or seasonal temperature rise. According to the invention, high-salinity water quality utilization is realized by utilizing a natural freezing and thawing cycle process, chemical reagents and special equipment do not need to be added, the adaptability to water quality is high, the technical difficulty is low, the investment is small, and the operation cost is low; the large-scale freezing and thawing pond is built by using the strip mine dump, so that the capacity is high, the efficiency is high, the occupied area does not need to be newly increased, and the influence on the ecological environment of a mining area is small.
本发明公开了一种基于露天矿排土场的高矿化度水淡化处理系统及淡化方法，本发明利用露天矿的剥离物料和排土场的广阔场地，建设冻融循环淡化系统，并划分为若干冻融子池以提高系统处理能力和布置灵活性；充分利用北方地区冬季寒冷的气候条件，将高矿化度水变为较低含盐度的冰和盐分含量更高的水，进一步利用矿区余热或季节性升温将冰融化为淡水。本发明利用自然的冻融循环过程实现高矿化度水分质利用，无需添加化学试剂和专用设备，对水质的适应性强、技术难度低、投资小、运行成本低；利用露天矿排土场建设大规模的冻融池，能力大、效率高，又无需新增占地，对矿区生态环境影响小。
