PURPOSE: A stacking type advanced water treatment system is provided which activates ozone oxidation treatment and blending to increase surface area of ozone oxidation treatment by stacking panels in an AOP (advanced oxidation process) contact pond in a zigzag form, thereby increasing ozone residence time. CONSTITUTION: The stacking type advanced water treatment system is characterized in that a plurality of panels are stacked in the upper part of air diffusers(8) of an AOP (advanced oxidation process) contact tank(1), a water penetrating panel hole(31) is formed at one side of the panels so that water penetrated into the water penetrating panel hole(31), one or more of the panels(33) are stacked in a zigzag form around the water penetrating panel hole(31) inside the AOP contact tank(1), a plurality of ultraviolet lamps(32) are installed in a discharged ozone space(2a) with the ultraviolet lamps(32) being spaced apart from each other in a certain distance, water passes through first to fourth AOP contact ponds to be treated by discharged ozone, ozone oxidation reaction is performed as fine ozone bubbles(71) discharged from the air diffusers(8) are being ascended along the panels(33) stacked in a zigzag form by buoyance, flow of the fine ozone bubbles(71) is changed up side down as the fine ozone bubbles(71) are passing through the water penetrating panel hole(31) so that the ozone treated water is mingled with water not sufficiently treated by ozone, and the repeating process increases residence time and surface area using the plurality of stacked panels, thereby maximizes ozone oxidation treatment efficiency.
