针对目前用电渗析法处理硝酸铵废水的现象,提出以电去离子处理作为硝酸铵废水深度处理,弥补现有电渗析处理的不足,达到硝酸铵废水处理系统“零排放”,做到废水资源化利用,硝酸铵和水全部回收.这种改良型电渗析处理方法,除可使浓水中氨氮的质量分数达10％以上外,系统出水氨氮的质量浓度小于或等于5mg,/L.%In view of the problems existing in the treatment of ammonium nitrate wastewater by electro-dialysis, electrodeionization technology was proposed to be used for the advanced treatment of the said kind of wastewater for the purpose of making up the shortcomings of the electrodialysis, realizing wastewater zero-discharge of the system, achieving resource utilization of wastewater and complete recovery of ammonium nitrate and effluent water. It was indicated that, using the said modified electrodialysis method to treat ammonium nitrate wastewater, the mass fraction of ammonia nitrogen in the concentrated water reached above 10% and the mass concentration of ammonia nitrogen in the effluent water was no higher than 5 mg/L.
