基于BDD电极的实际含能材料废水中氮转化电化学处理
Using BDD Electrode for Electrochemical Treatment of Nitrogen in Real Energetic Material Wastewater
摘要
Abstract
The pilot-scale energetic material wastewater is a kind of wastewater which is extremely difficult to degrade,contain-ing high concentrations of various nitrogen-containing compounds,such as ammonia nitrogen(NH3—N),nitrite(NO2-),ni-trate(NO3-),and other organic pollutants.To realize the efficient and directional removal of these nitrogen-containing com-pounds,boron-doped diamond(BDD)electrodes were prepared by the hot-filament chemical vapor deposition(HFCVD)meth-od 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 chlo-ride(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 du-al 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 high-ly effective method in the rapid and selective degradation of energy material wastewater,especially when using 0.1 M NaCl as electrolyte.关键词
