摘　　要：采用电絮凝技术对页岩气压裂返排液进行处理,考察了各操作条件对页岩气压裂返排液处理效果的影响,确定了电絮凝处理的最佳实验条件:阴阳极材料均为铝板,电流密度10.0 m A/cm2,极板间距3 cm,反应时间60 min,p H=7。电絮凝工艺对低浓度页岩气压裂返排液具有较良好的处理效果,可望成为页岩气压裂返排液达标排放组合工艺的重要单元。The electric flocculation technology has been used for treating the shale gas fracturing flow back fluid,and the treatment effects of operating conditions on shale gas fracturing flow back fluid investigated. The optimal ex-perimental conditions of electric flocculation technology are determined as follows：aluminum plates are selected asthe cathode and anode materials,the current density is 10.0 m A/cm2,plate spacing 3 cm,reaction time 60 min,andp H=7. The experimental results show that the electric flocculation technology has good treatment effects on low con-centration shale gas fracturing flow back fluid. It is expected to be an important unit of standard discharge combinedprocess of shale gas fracturing flow back fluid.
