页岩气废水资源化处理可行性探索

The feasibility study on shale gas wastewater resourcing treatment

通过对页岩气废水及高盐废水处理技术调研,明确蒸发结晶是页岩气废水资源化处理的有效途径之一。通过真空蒸发实验,蒸发后的冷凝水满足排放要求,结晶盐符合工业盐二级要求,蒸发结晶可作为末端处理技术实现页岩气废水的资源化利用。

Through the investigation of shale gas wastewater and high salt wastewater treatment technology,it is clear that evaporation crystallization is one of the effective ways of shale gas wastewater resourcing treatment.By the experiment,it shows that the condensed water can meet the requirements of emission and the crystallization salt meet the industrial salt requirements（Ⅱ）which can be used as chemical raw materials.So,evaporation crystallization technology as the post-treatment could make the resourcing of shale gas wastewater come true.
