摘　　要：在快速发展的页岩气产业中,如何在保证页岩气开采盈利能力的同时,保护公众健康和环境,页岩气开采废水的管理是一项重大挑战。从氯化物可能带来的环境风险及危害上论述了脱盐的必要性,讨论了废水达标排放可参考的排放标准及相关的脱盐技术,表明了页岩气开采废水达标排放处理需选择合理的"预处理+深度脱盐"工艺,以降低氯化物可能带来的环境风险及危害。In the rapidly developing shale gas industry,how to protect public health and the environment while maintaining the profitability of shale gas extraction is a major challenge.In this article,the necessity of desalination was expounded from chloride could risk and harm to the environment,and the discharge standards for qualified wastewater discharge and relevant desalination technologies were discussed,and indicated that it is necessary to select a reasonable process of " pretreatment + deep desalination" for treatment shale gas extraction wastewater to reduce the environmental risks and hazards brought by chloride.
