摘要： A gas-dissolving device can dissolve a gas in a liquid at a high concentration, and can maintain the concentration of a dissolved gas even in a state in which a circulation operation has been stopped. The gas-dissolving device of the present invention comprises: a dissolving tank for receiving a liquid and a gas from each of a circulation pump and a gas source, and discharging a liquid/gas mixture with an increased dissolved gas concentration in the liquid; and a pressurization dissolving part which is fluidically connected to the dissolving tank, and which has a wound coil portion or a plurality of bent portions to further increase the concentration of the dissolved gas, and thus discharge a high-concentration-gas solution. The dissolving tank includes: a plurality of dispersing trays, which are each formed in a shape of having an inclined surface extended in the outer downward direction; and a plurality of water-collecting trays, which are each formed in a shape of having an inclined surface extended in the inner downward direction and each have a through-hole formed at the lower end thereof, wherein the plurality of dispersing trays and the plurality of water-collecting trays are alternately arranged in the vertical direction.
