Development of electrodes (1)

  1. 1. Development of Three-Dimensional Electrode in Wastewater Treatment Huang Yaokun, Wang Can*, Wang Fen*, Ji Min* School of Environmental Science and Engineering Tianjin University Tianjin 300072, ChinaAbstract—Three-dimensional electrode technology shows great II.potential in wastewater treatment. In this paper, thedevelopments of the technology were systematic introduced.The optimization of feeder electrode or particle electrodeswere becoming one of the research focuses of this filed. Severalnovel particle electrodes including new carbon material andmetallic oxides had been widely studied. The mechanisms to A.degrade pollutants were due to the direct and indirectoxidation, 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 electrodetechnology. Some corresponding potential solutions for these H2O2 ·OHproblems had also been proposed.Keywords: three-dimensional electrode; feeder electrode; particleelectrode; wastewater treatment I. three-dimensional electrode particle electrode bed electrode conversion combustion H2O OH- ·OH ·OH ·OH MOx+1 ·OH 1 2 H2O OH- ·OH Cl- 3 Cl- H2O2 H2O2 Fenton ·OH 978-1-4577-0290-7/11/$26.00 ©2011 IEEE 3052
