Abstract—Three-dimensional electrode technology shows great
II.
potential in wastewater treatment. In this paper, the
developments of the technology were systematic introduced.
The optimization of feeder electrode or particle electrodes
were becoming one of the research focuses of this filed. Several
novel particle electrodes including new carbon material and
metallic oxides had been widely studied. The mechanisms to A.
degrade pollutants were due to the direct and indirect
oxidation, which took place near the electrode area.
Furthermore, it was pointed out that high operation cost,
feeder electrodes corrosion and particle electrodes inactivation B.
were the main problems of three-dimensional electrode
technology. Some corresponding potential solutions for these
H2O2 ·OH
problems had also been proposed.
Keywords: three-dimensional electrode; feeder electrode; particle
electrode; wastewater treatment
