Abstract:
Various kinds of combined electro-catalytic oxidation technologies for treating refractory organic wastewater is introduced. The combined electro-catalytic oxidation technologies mainly include photoelectro-catalytic oxidation, ultrasound electro-catalytic oxidation, ozone electro-catalytic oxidation, electro-catalytic-bio-reaction and membrane filtration electro-catalytic oxidation. The properties, advantages and disadvantages of the combined electro- catalytic oxidation technologies are discussed, respectively. The analysis shows that the combined electrocatalytic oxidation technologies used for treating wastewater have synergic effect. Their industrialized will soon be realized in the near future through researches on the electro-catalytic materials and the process technologies.
