| 摘 要： | 高铁酸钾是一种新型高效的多功能水处理剂,而垃圾渗滤液中氨氮浓度过高会降低生化处理中微生物的活性,需要进行前处理去除一部分氨氮.作者通过模拟实验得出用高铁酸钾去除废水中氨氮,在m(高铁酸钾):m(氨氮)=4:1,pH为9时,处理效果最佳,而处理效果受温度影响不大.高铁酸钾对垃圾渗滤液中氨氮去除率可达60%.

| Abstract: | Potassium ferrate is a new type of efficient multi-functional water treating agent.The activity of microorganisms will be restrained during the micro-chemical treatment process,when the concentration of the ammonia-nitrogen is too high in the landfill leachate.It is necessary to do some pretreatment to reduce the ammonia-nitrogen.The best conditions for the potassium ferrate to dispose ammonia-nitrogen are:the dose of the potassium ferrate is four times of ammonia-nitrogen,and the pH is 9.The removal rate of ammonia-nitrogen is almost free of the influence of temperature.The experiments indicate that potassium ferrate is a good pretreating agent which can remove the highly concentrated ammonia-nitrogen in the landfill leachate and the removal rate can be as high as 60%. |
