电氧化法脱除废水中氨氮

Electro-oxidation Treatment of Ammonia in Wastewater

废水中氨氮以游离氨(NH3)和离子态氨(NH4+)形式存在。电氧化在氨氮废水处理方面极具发展潜力,通过直接和间接电氧化可去除垃圾渗滤液、制革废水、养殖废水等诸多废水中的氨氮。电极材料、电流密度、废水pH值、氯离子浓度、温度、以及其它物质等因素对氨氮电氧化过程产生影响。

Electrochemical oxidation method is an advanced oxidation technology. It has great potential for development in ammonia nitrogen wastewater treatment. Ammonia nitrogen can be removed from landfill leachate, tannery wastewater, aquaculture wastewater and other ammonia wastewater through direct and indirect electro-oxidation. In the process, removal rate, current efficiency and energy consumption is influenced by many factors, such as the pH value of waste water, chlorine ion concentration, electrode material, current density and COD.
