Application of Fe-Si-B amorphous alloy electrode in the treatment of simulated port oily wastewater by electro-fenton method
Simulated wastewater including contaminants such as emulsified oil was created based on the composition of oily wastewater at ports.The performance of an anode made of Fe-Si-B amorphous alloy in an electro-fenton system for decomposing emulsified oil effluent was examined.The effects of current density,starting pH,and H2 O2 dose on the reaction were studied,and process parameters were modified.The experimental findings reveal that when the reaction period is 40 minutes,the current density is 30 mA/cm2,the starting pH value is 3,and the H2 O2concentrationis20 g/L,theoilremovalrateofwastewatermayreach99.91%.Thepossiblereaction pathway for the electro-fenton method's degradation of emulsified oil wastewater was analyzed.And the results shows that the strong oxidation of hydroxyl radicals generated in the electrio-fenton system partially oxidizes the original wastewater's long-chain organic compounds into easily biodegradable short chain alkanes.This gives a solid starting point for the treatment of emulsified oil-containing wastewater and the practical application of Fe-Si-B amorphous alloy as an electrode material.
