铁元素在废水处理工艺中的应用研究进展

综述了不同价态的铁在废水处理工艺中的应用原理,及铁碳微电解工艺、双金属催化工艺、Fenton法、类Fenton工艺、UV/Fe2+(Fe3+)催化臭氧工艺、高铁酸盐应用于水处理的研究应用现状。对比了催化体系与单独臭氧体系对水中有机物的去除效果。得出Fe2+(Fe3+)作为催化剂应用于高级氧化法是今后应继续深入研究并是最有前景的难降解废水处理工艺的结论。

Research progress of irons applied in wastewater treatment

The application principles of iron with different valent states in wastewater treatment and the current status of the research and the application of iron-carbon microelectrolysis process,bimetallic catalytic process,Fenton process,Fenton-like process,UV /Fe2+(Fe3+) catalytic ozonation process and ferrate process in water treatment were reviewed.The degradation of organic compounds by catalytic ozonation system and single ozonation system was compared,it could draw a conclusion from the result that,the use of Fe2+(Fe3+) as the catalyst in advanced oxidation process should be deeply investigated,and the said process must be the most promising technique for hard-degradable wastewater treatment in the future.
