A novel continuous-flow electrochemical reactor was designed for oilfield wastewater advanced treatment. Magnetic steel slag particles were prepared as particle electrodes in the reactor. The best preparation condition of steel slag particle electrodes is obtained via orthogonal and single factor experiments. The resulting samples were characterized by scanning electron microscope and vibrating sample magnetometer. It was demonstrated that saturation magnetic intensity of the particle was 1.6389 emu/g. The process parameters and the total organic carbon (TOC) removal kinetics were investigated. Result showed that the reactor could remove over 85% TOC in 2 h, which was considered to be effective.
