求１項記載の接触曝気槽。[Scope of Claim for Utility Model Registration] (1) A contact aeration container with an airtight structure that accommodates water to be treated and a contact material, and a structure that maintains the airtightness of the contact aeration container and maintains a constant water level in the contact aeration container. a pair of inflow and outflow transfer pipes connected to the contact aeration container; an exhaust device connected to the contact aeration container above the water surface of the water to be treated and capable of being shut off; and an aeration device disposed below the contact material. The pressure of the gas above the water level of the water to be treated is reduced by exhausting and blocking the gas supplied from the aeration device, passing through the water to be treated, and being discharged to the top of the water to be treated from the contact aeration container. A contact aeration tank in which the contact material can be exposed from the water to be treated to the atmosphere by increasing or decreasing the amount of water to be treated stored in the contact aeration container. (2) The contact aeration tank according to claim 1, wherein the pair of inflow and outflow transfer pipes are connected to the contact aeration container below the water surface of the water to be treated. (3) The pair of inflow and outflow transfer pipes are configured such that the first outflow and inflow transfer pipe is connected to the contact aeration container below the water surface of the water to be treated, and the first outflow and inflow transfer pipe is connected to the contact aeration container above the water surface of the water to be treated. The contact aeration tank according to claim 1, comprising a second inflow/outflow transfer pipe.
