摘　　要：单质铁是地球上分布较广的金属,价格低廉容易获得。概述了单质铁在厌氧生化处理系统中的强化作用和特性,包括铁的氢腐蚀作用、还原作用和催化内电解作用。概述了单质铁以催化内电解的作用在难降解的工业废水处理方面的应用,以及包括铁屑和铁刨花的单质铁对城市污泥和餐厨垃圾的厌氧发酵产甲烷方面的应用。分析和展望了单质铁应用的发展趋势。Elemental iron is a widely distributed metal on the earth, which is inexpensive and can be easily obtained.This paper summarized the enhancement mechanisms of zero valent iron in anaerobic digestion treatment system,including the effects and characteristics of iron of hydrogen corrosion, reduction and catalytic internal electrolysis.Moreover, the application of elemental iron in the treatment of refractory industrial wastewater by catalytic internal electrolysis were summarized, and including iron scrap and iron shavings in the anaerobic digestion of municipal sludge and food waste for methane yield as well. Finally, the development trend of the application of zero valent iron was analyzed and prospected.
