Studies on the Removal of Humic Acid by Electro-Flotation—Photocatalytic Oxidation of Suspended TiO₂

Abstract:

This paper gives an experimental research on slightly contaminated raw water by utilizing the combined technology of electro-flotation and suspending TiO₂ photochemical catalysis. During the static experiment of degrading humic acid by electro-flotation—suspended TiO₂ photochemical catalysis, the ratio of COD_Mn removal reaches 87.8% in such conditions as two ultraviolet germicidal lamps of 10W, the voltage of 20V, the current of 0.4A, 0.5cm intervals of two groups of plates, the TiO₂dosage of 1g/L and the reaction time of 150 minutes. The preferable synergistic effect can be achieved when combining electro-flotation and photocatalytic oxidation together.
