Gongye shui chuli采用电化学沉积法去除神东矿区大柳塔煤矿矿井水硬度，分析了阴极材料结构与形貌对矿井水硬度去除的影响，结果表明，电极表面磨砂结构更有利于钙、镁离子的电沉积去除，网状形貌阴极可进一步强化电沉积效率。同时探讨了初始硬度、电流密度、电极数量、pH等参数对电化学去除矿井水硬度的影响。在中性条件下，初始硬度为310 mg/L，电流密度范围为2~6 mA/cm2，阴极和阳极极板面积之比3∶2时，矿井水硬度去除率可在180 min内约达90%。随着硬度/重碳酸氢盐碱度的不断降低，硬度去除效率也不断增加 ...

Gongye shui chuli反渗透工艺是目前处理高矿化度矿井水常用的工艺，该工艺浓缩分质后会产生超高矿化度的氯化钠、硫酸钠浓缩盐水。这种浓缩盐水只能蒸发结晶处理后方可排放，传统的蒸发结晶工艺由于能耗非常高限制了其应用。近来年，相对能耗较低的MVR蒸发结晶工艺在国内外得到较多应用。针对煤矿矿井水浓缩的超高矿化度特点，在MVR工艺的基础上对蒸发器进行改良，增设由高温超导材料制成的原液预热器，进一步提高传热效率。改良制造的MVR蒸发器（150 kg/h）应用于陕西小纪汗煤矿超高矿化度浓水的应用试验中，传热面积由2.80 m2提高至4 ...
