摘要
探讨了电渗析的原理,分析了pH值对电渗析工艺去除废水中氨氮的影响,介绍了试验装置及方法,得出了偏酸性时氨氮去除率下降剧烈,偏碱性时氨氮去除率下降不是很明显,对于主要污染物为氨氮的废水,其去除效果几乎不受pH值影响的结论。
It discusses the working law of electrodialysis, analyses the influence of pH to the technique of applying electrodialysis to eliminate ammonis and nitrogen in wastewater, introduces experiment equipment and method and gets the conclusion that when it is weak acid, ammonia and nitrogen elimination rate decreases violently, when it is weak alkaline, ammonia and nitrogen elimination rate decreases moderately, when the main pollutant is mmonia nitrogen wastewater, elimination effect is almost not influenced by pH.
