<p>PURPOSE:To prevent generation of a sludge cake in a buffer zone between a partition under the water surface and a partition above the water surface. CONSTITUTION:The inside of the body wall 20 is separated by a pair of the partitions above the water surface 24, 24 to the reaction part 40 and the sedimentation part 41 and the inside of the reaction part 40 is provided with a pair of the air lift partition 22, 22. A pair of partitions under the water surface 23, 23 is arranged between a pair of air lift partitions 22, 22. A pair of the partition above the water surface 24, 24 and the upper end 32, 32 of a pair of the partition under the water surface 23, 23 sink under the water surface.</p> |
