PROBLEM TO BE SOLVED: To provide a high-reaction efficiency apparatus for gas reaction of a liquid to be treated.SOLUTION: A gas reaction apparatus 10 for contacting and reacting a gas G with a liquid W1 to be treated comprises: a reaction tank 11; a feed passage 81 for the liquid W1 connected to the reaction tank 11; a feed pump P1 provided on the midstream of the feed passage 81; a gas G-mixing path 83 connected to the feed passage 81 at the upstream side of the feed pump P1; a filter 21 through which the liquid W1 fed into the reaction tank 11 is passed to separate the gas G mixed in the liquid W1 from the liquid W1; and a circulation path 83 whose one end is connected to the reaction tank 11 and the another end is connected to the feed passage 81 at the upstream side of the feed pump P1. The apparatus 10 is composed so that the gas G accumulating in the reaction tank 11 circulates through a circulation path 84. |
