With the continuous advancement of oilfield technology and the continuous development of the shale gas revolution, fracturing stimulation requires a large amount of fracturing fluid. The on-site water is generally composed of 70 % of the river channel or groundwater and 30 % of the fracturing flowback fluid. The river water is generally used directly without treatment. The treatment of the flowback water adopts procedures such as sterilization, sedimentation, and filtration. Through the comprehensive treatment of the operating sewage, the purpose of reusing the fracturing fluid flowback fluid is achieved.
