摘要
催化铁技术作为一种新型的物化-生化复合式处理工艺,因适应性强、见效快、原料价廉易得,不仅在降解难处理的含卤、含硝基等有机物时表现出色,在脱氮除磷方面同样也具有良好的应用前景。着重介绍了催化铁技术在污水脱氮除磷方面的作用机理,以及该技术的实际研究和工程化应用情况,分析了对该技术有效应用影响较大的几个主要因素。最后指出当前需要对该技术应用中面临的消除催化铁表面钝化、铁对反硝化生物脱氮的影响做进一步深入研究。
As a new combined type physico-chemistry-biochemistry treatment process,catalyzed iron technology is characterized by strong adjustability,fast efficiency,and cheap raw material.Not only does it have excellent effects on degrading the refractory organisms which contain halogen and nitro compounds,but also has remarkable application prospects for denitrification and dephosphorization.The reaction mechanism of catalyzed iron technology applied to the denitrification and dephosphorization from sewage and the actual research and application in engineering are introduced emphatically.Several main influential factors of catalyzed iron technology which have great impacts on its effective application are analyzed.At the end,it is pointed out that further advanced research should be on the problems existing in the application of the technology,such as the elimination of catalyzed iron surface passivation and the effect of iron on biological denitrification.
