By studying and comparing the effects of different treatment processes on shale gas-fracturing produced water, the process of electrocoagulation-O₃ combined treatment of produced water was designed. Taking COD and TSS as indictor, the effects of pH, current density, electrode spacing, electrolysis time and O₃ aeration on the removal efficiency of COD and TSS are discussed. The experimental results showed that the most suitable conditions are as follows:pH is 8.0, the current density is 1250 A/m², the distance between plates is 2 cm, the electrolysis time is 6 min and the O₃ ventilation is 40 L/h. Under these conditions, the COD and TSS removal rate of produced-water is 98.3% and 95.9% respectively. The color, turbidity, oil, and NH₄-N pollution of the produced water reach the national emission standards after combined treatment with Electrocoagulation-O₃.
