In recent years, with the rapid development of China's industrial, wastewater emissions is increasing year by year, and water pollution are trending diversification. The wastewater sources contain high concentrations of organic is increasing, the resulting organic wastewater with high concentrations and difficult decomposition cause dire threats to human health and existence. While traditional water treatment method can effectively reduce the concentration of wastewater organic matter, improve water quality, but there are still much less than in the application of high concentration organic wastewater. Electro chemical methods of wastewater treatment are easier to control, non-polluting or less pollution, a high degree of flexibility and economy. And it is a hot spot research in the field of current environmental science and engineering. Diamond film with its excellent electrochemical properties, has gradually become one of the best electrode material in the field of electrochemistry and electrochemical engineering, and the application and research on sewage treatment increasingly widespread. This paper have a systematic study on how to receive the physical and electrochemical nature of Boron-doped diamond film electrode by the Chemical Vapor Deposition method, explored the Electro catalytic Properties of Electrode to P-nitro phenol, and explored its applications by electrochemical method in the treatment of its ultra-high COD refractory organics. Have studied the electrochemical oxidation characteristics, that under acidic conditions, p-Nitro phenol at Boron-doped diamond film electrode, through cyclic voltammeter, AC impedance method. Developed the sewage treatment equipment applicable to diamond film electrode. Use of the equipment has derogative processed printing and dyeing wastewater of Nan Shan Group. Inspected the impact of the electrolysis time, voltage and pole spacing on electrochemical degradation of efficiency. The results show that the diamond thin film electrode has excellent water degradation, COD removal rate near 100% current efficiency up to more than 0.8.
