The pilot-scale energetic material wastewater is a kind of wastewater which is extremely difficult to degrade， containing high concentrations of various nitrogen-containing compounds， such as ammonia nitrogen （NH₃─N）， nitrite （NO₂^-）， nitrate （NO₃^-）， and other organic pollutants . To realize the efficient and directional removal of these nitrogen-containing compounds， boron-doped diamond （BDD） electrodes were prepared by the hot-filament chemical vapor deposition （HFCVD） method and utilized to degrade the wastewater. The effects of electrolyte composition and concentration， modified electrode type， and electrolysis device structure on the degradation efficiency were investigated. It demonstrated that adding 0.1 M sodium chloride （NaCl） electrolyte to energetic material wastewater could improve the selectivity of NH₃─N direct conversion to nitrogen （N₂）. Using Cu/BDD and Ni/BDD cathodes accelerate the conversion process of high-valent nitrogen to NH₃─N. Under the dual electrolysis cell structure system， employing Cu/BDD and Ni/BDD electrodes as anodes improve the degradation rate of NH₃─N conversion to N₂. Therefore， the approach utilizes metal-modified BDD electrodes as anodes， is expected to be a highly effective method in the rapid and selective degradation of energy material wastewater， especially when using 0.1 M NaCl as electrolyte.
