Claims

[Scope of Claim for Utility Model Registration] A drainage device for draining water that has entered the inside of an air pipe that is disposed below the water surface of an aeration tank and supplies air into the water, which is connected to the air pipe. The drain block is equipped with a drain block, a drain pipe connected to the upper part of the drain block and opened to the atmosphere, and an on-off valve provided on the drain pipe, and the drain block has an upper part connected to the drain pipe inside the drain block. A drainage space is formed in the lower part of this drainage space that communicates with the air pipe, and a drainage hole that communicates with the air pipe is formed in the upper part of this drainage space so that the rising water flow by the air lift is formed in the upper part of this drainage space. A drainage device characterized by forming air holes that generate air.
