<p>PURPOSE:To reduce the setting space and to simplify the mounting work in the septic device for sewage by using a discharge suction part also as the diffusion part for blowing air. CONSTITUTION:A hollow chamber 31 is used as the part of a waste water passage 3 in a water tank, a water passage port 36 is provided on the lower surface side of the clamber 31 and a diffusion hole 37 on the upper surface side of the chamber 31, the air from its source 41 is supplied to the chamber 31, and hence the chamber 31 is used as the waste water suction part and diffusion part for blowing air. Consequently, the number of parts is reduced, the setting space in the water tank is diminished, and the inside of the water tank is effectively utilized. Meanwhile, since an air pipe 42 for blowing air into the chamber 31 is connected to the waste water passage 3 outside the water tank, a hole for the air pipe need not be formed in the wall of the water tank, and the mounting structure of the air feeder is simplified.</p> |
