摘　　要：针对城市污水处理厂出水氨氮偏高和不达标问题,本研究采用电化学氧化法对低浓度模拟氨氮废水进行试验,分别考察了电流大小、初始pH值、初始Cl-浓度对氨氮去除效果的影响。结果表明,模拟水初始pH值为7.41、3‰NaCl浓度、电解电流为8 A时,电解1.5~2 h氨氮可完全去除,而且此时所需能耗也较低。该方法可用于低浓度废水的深度脱氮处理,具有良好的应用前景。In view of the high ammonia nitrogen concentration and substandard effluent of urban sewage treatment plants,the electrochemical oxidation method was used to test the low-concentration simulated ammonia nitrogen wastewater in this study.The effects of current intensity,initial pH value and initial Cl-concentration on the removal effect of ammonia nitrogen were investigated respectively.The results showed that when the initial pH value of the simulated water was 7.41,the concentration of NaCl was 3‰,and the electrolytic current was 8 A,the ammonia nitrogen could be completely removed in 1.5~2 h,and the energy consumption at this time was also low.This method could be used for the deep denitrification treatment of low-concentration wastewater,which would have good application prospects.
