The present invention relates to an aquarium sterilization and purification apparatus, and more particularly, to an aquarium sterilization purification apparatus capable of primarily sterilizing and purifying water in an aquarium using plasma, and secondarily sterilizing and purifying gas diluted in water . The aquarium sterilization purification apparatus according to the present invention comprises: a case； A pump provided inside the case for drawing water from the aquarium； A plasma sterilizer provided in the case to form a separate internal space and converting the aquarium water drawn up by the pump into sterilized and sterilized water using plasma； A gas-liquid separator provided adjacent to the plasma sterilizer and separating ozone and polluted gas diluted in sterilized water purified by the plasma sterilizer； And an air purifying filter provided adjacent to the gas-liquid separator and configured to purify the ozone and the polluted gas separated by the gas-liquid separator, wherein the gas- A water inflow portion provided adjacent to a side surface of the inner upper surface for introducing the sterilized water sterilized by the plasma sterilizer into the interior of the gas-liquid separator； A water discharging portion for discharging the sterilizing water into the external aquarium when the sterilizing water flowing through the water inflow portion reaches a predetermined position； And a separation gas discharging portion provided on the upper surface of the separator to allow the ozone and the polluted gas to flow to the air purifying filter, wherein the water inlet includes a gas-liquid separator for separating the gas- The sterilizing water flows through the inner wall of the gas-liquid separator to separate the ozone and the polluted gas from the sterilizing water so that the separation effect can be maximized.본 발명은 수족관살균정화장치에 관한 것으로, 보다 구체적으로 플라즈마를 이용하여 수족관 물을 1차적으로 살균 및 정화하고, 2차적으로 물에 희석되어 있는 기체를 살균 및 정화할 수 있는 수족관살균정화장치에 관한 것이다.본 발명에 따른 수족관살균정화장치는,
