Abstract Through a variety of material screening experiments, Al was selected as the added metal and constituted a multiple micro-electrolysis system of Fe-C-Al. The metal proportion of alloy-structured filler was also analyzed with the best Fe-C-Al ratio of 3:1:1. The regular Fe-C-Al multiple micro-electrolysis fillers were prepared using a high-temperature anaerobic roasting method. The optimum conditions for oil refinery wastewater treated by Fe-C-Al multiple micro-electrolysis were determined to be an initial pH value of 3, reaction time of 80 min, and 0.05 mol-L Na2SO4 additive concentration. The reaction mechanism of the treatment of oil refinery wastewater by Fe-C-Al micro-electrolysis was investigated. The process of the treatment of oil refinery wastewater with multiple micro-electrolysis conforms to the third-order reaction kinetics. The gas chromatography–mass spectrometry GC–MS used to analyze the organic compounds of the oil refinery wastewater before and after treatment and the Ultraviolet–visible spectroscopy UV–VIS absorption spectrum analyzed the degradation process of organic compounds in oil refinery wastewater. The treatment effect of Fe-C-Al multiple micro-electrolysis was examined in the continuous experiment under the optimum conditions, which showed high organic compound removal and stable treatment efficiency.
