Claims

[Scope of Claim for Utility Model Registration] 1. In a septic tank in which aerobically treated water containing sludge in the contact aeration chamber is returned to a sedimentation separation chamber or an anaerobic filter bed, the treated water in the contact aeration chamber is pumped up. At the same time, an air blowing pipe with an air volume adjustment valve is attached to the riser pipe for this purpose, a gas-liquid separation chamber is formed in the upper part of the riser pipe, a rectifying buttful is installed on the liquid outflow side of this gas-liquid separation chamber, and A sludge return device for a septic tank, characterized in that a notch is provided on the opposite side of the liquid outflow portion of the gas-liquid separation chamber to keep the water level of the treated water constant. 2. Claim 1, wherein a flow control plate whose vertical position is adjustable is attached to the notch.
Sludge return device for the septic tank described.
