Rapid organism degradation function of Fe-based alloys in high concentration wastewater

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.
