Abstract: To reduce the negative effect of algae on conventional water treatment,The nanocatalytic-electroflotation process is used to treat the lake water.The results indicate that, Nanocatalytic-electroflotation process is a technique widely kill algae, Cyanobacteria were the dominant algae in the lake water by treatmenting with Nanocatalytic-electroflotation process, the average removal rate of algae concentration as high as 99.1%. The effects of current density,residence time and electrode gap on algae removal efficiency are investigated by means of orthogonal test.The results show that the sequences of influential factors which affect the algae removal efficiency are as follows:current density> residence time>electrode gap. Comprehensive economic consideration, the optimum process conditions are: current density is 5 mA/cm2, the residence time of 6 minutes, electrode gap is 10mm.
