The treatment of high concentration organic wastewater using Fe-based alloys in the Fenton-like system was investigated. The removal rate of COD by using the Fe₇₈Si₉B₁₃ metallic glass (MG) reached 85 % , about 30 % and 40 % higher than that by the Fe₇₈Si₉B₁₃ crystalline alloy (CA) and by the traditional material Fe⁰ used in Fenton-like system, respectively. The treatment result by the Fe₇₈Si₉B₁₃ MG was more than 65 % higher and 50 times faster than that of the traditional aeration process with the same addition of Fe⁰. It has been proved that the Fe₇₈Si₉B₁₃ MG played an excellent catalytic activity in the oxidative degradation of organic compounds, and its microstructure transformation during the corrosion process promoted the degradation efficiency of the wastewater treatment process.
