Research on Algae Removal by Electro-flotation/Photo-catalytic Oxidization Combined Process

The lake-type raw water was treated in Photo-catalytic Oxidization reactor. Under the condition of the inflow discharge control in 15L/h, the padding packing compares 2/5, UV lamp 30W, added no chemicals, pH 7.35, use the electro-flotation to treat it by two groups of plates to treat the water continuously. Then investigate the removal effect of pollutants after electro-flotation/Photo-catalytic Oxidization Combined Process. The results indicate that after the process the average removal rates of CODMn, TN and UV254 can reach 45.21%, 20.12% and 55.11% respectively and the average removal rate of Chl-a can reach 82.0% and its removal rate is steadily under 75%~89% when the Chl-a of raw water is 4.52mg/m3 during continuous operation for 9 hours.
