PURPOSE : An aeration device for self-electric generation type water purifying system is provided to maximize the contact area between air and polluted water within a range and to activate reaction of dissolution, thereby maximizing the content of dissolved oxygen. CONSTITUTION : An aeration device for self-electric generation type water purifying system comprises a pump (210), an air supply pipe (220), a bubble dispersing panel (240), and bubble dispersing elements (250). The air supply pipe guides air supplied by the pump to the bottom of a reaction chamber. The bubble dispersing panel is contained in the bottom of the reaction chamber to divide the air in the reaction chamber into small particles. The bubble dispersing elements is contained in the top of the reaction chamber to redivide and coalesce air and to make the air flow irregularly.
