成したことを特徴とする脱窒処理装置。 There is an anaerobic treatment tank into which raw water flows, a contact aeration tank in which a large number of string-like contact materials are stretched, and a part of the treated water flows out while performing catalytic oxidation and aerobic treatment water circulation through aeration. The denitrification reaction chamber is installed in an aeration tank, has a large number of string-like contact materials stretched therein, and has an inverted opening, into which anaerobic treated water is introduced from the anaerobic treatment tank, and the lower end of the denitrification reaction chamber is opened. A protruding plate is provided on one side of the contact aeration tank to protrude into the circulation path of the aerobic treated water circulating in the contact aeration tank and introduce a part of the circulating water, and the top wall is placed facing the circulation path to collect the denitrification treated water. 1. A denitrification treatment apparatus, characterized in that a plurality of through holes are formed through which a portion is drawn out by suction.
