神东矿区矿井水深度除盐处理效果论证

Proof of Effect of Deep Desalting Treatment for Mine Water in Shendong Mining Area

神东矿区位于北方煤炭资源非常丰富的地区,矿区开采后产生的矿井水属于高矿化度矿井水。为了节约矿区水资源,矿井水经常规处理后回用于矿区生态绿化建设,在个别地方引起了土壤次生盐碱化,植物出现枯萎、死亡现象。对神东矿区生态建设中矿井水净化处理利用现状和存在的主要问题进行了阐述,针对研究区水质特点,论证了反渗透技术对高矿化度矿井水的深度除盐回用效果,为神东矿区的中水再利用提供了一定的参考。

Shendong mining area is located in northern China,where the coal resources are very rich.Mine water after the mining process is highly-mineralized.In order to save resources,mine water is reused in ecological construction after the conventional treatment.This causes soil secondary salinization,plants withering and even death in a few places.The present situation and main problem of mine water treatment and reusing in ecological construction of Shendong mining area are analyzed.According to the water quality characteristics of the study area,the effect of reverse osmosis treatment technology for highly-mineralized mine water is discussed to provide some reference to the reuse of mine water in Shendong mining area.
