摘　　要：采用微波条件辅助催化氧化高浓度氨氮废水,通过实验研究了催化剂种类、敏化剂、微波加热时间、溶液pH对氨氮去除效果的影响。结果表明,溶液pH值为10,同时添加氧化剂过氧化氢、催化剂氧化铜、敏化剂沸石、活性炭后氨氮脱除效果最佳,微波功率为750W下,辐射时间10min,氨氮去除率接近95%。The influence of the kind of catalysts, pH value, microwave irradiation time and microwave sensitizers on the removing efficiency of ammonia nitrogen in ammonia nitrogen containing wastewater have been studied through experiments. The results show that the removing rate of ammonia nitrogen could reach 95% , when the solution pH value is 10, microwave is 750 W and the time of microwave radiation is 10 min with the addition of H2O2, CuO, zeolite and activated carbon.
