摘　　要：The electrochemical treatment of wastewater containing chlorophenols （2-monochlorophenol, 4-monochlorophenol, 2,4-dichlorophenol, 2,4,6-trichlorophenol） was carried out experimentally with synthetic boron-d0ped diamond （BDD） thin film electrodes. Current vs time curves under different cell voltages were measured. Removal rate of COD, instant current efficiency （ICE） and energy consumption were investigated under different current densities. The influence of supporting media is reported, which plays an important role in determining the global oxidation rate. The oxidative chloride is stronger than peroxodisulphate. The electrochemical characteristics of boron-doped diamond electrodes were investigated in comparison with active coating Ti substrate anode （ACT）. The experimental results show that BDD is markedly superior to ACT due to its different absorption properties.The electrochemical treatment of wastewater containing chlorophenols (2-monochlorophenol,4-monochlorophenol,2,4-dichlorophenol,2,4,6-trichlorophenol) was carried out experimentally with synthetic boron-doped diamond (BDD) thin film electrodes.Current vs time curves under different cell voltages were measured.Removal rate of COD,instant current efficiency (ICE) and energy consumption were investigated under different current densities.The influence of supporting media is reported,which plays an important role in determining the global oxidation rate.The oxidative chloride is stronger than peroxodisulphate.The electrochemical characteristics of boron-doped diamond electrodes were investigated in comparison with active coating Ti substrate anode (ACT).The experimental results show that BDD is markedly superior to ACT due to its different absorption properties.
