Abstract: Coalbed methane is an important energy resource，but a large amount of coalbed methane drainage will be produced during the mining process.In order to treatment the organic and inorganic salts and pollutants of coalbed methane drainage effectively，solve the problem that the coalbed methane drainage is difficult to treat，in this study，nano-ceramic electrocoagulation technology is proposed for advanced treatment of coalbed methane drainage.The results show that in the electrolysis time of 60 min，the plate spacing of 12 mm，current density of 9 mA/cm²，2 of the number of plates and the suction pump outlet pressure is 0.08 MPa，the process of COD，SS，total salt，Fe and oil pollutants index can meet the “surface water environmental quality standard” (GB3838—2002) in the V class water standard.
