Wherein, when the first floating body 3 is completely or partially submerged in the sewage, the buoyancy force applied to the first floating body 3 is less than the sum of the self gravity of the first floating body 3 and the suction force applied to the first floating body. When the second floating body 5 is completely submerged in the sewage, the buoyancy to which the second floating body 5 is subjected is greater than the sum of the self-gravity of the second floating body 5 and the suction force to which the second floating body 5 is subjected.
