Abstract

PURPOSE: To prevent the deposition of sludge near a circular portion simply without damaging the function of tank.
CONSTITUTION: The waste water treatment tank has linear sections which are partitioned by the partition wall 2 and connected with each other at the end 6 of the partition wall and which is provided with an apparatus by which waste water is circulated. In the waste water treatment tank, having a groove or waterway form, the deposition of sludge can be prevented by producing an additional flow by means of the openings 8 formed in the neighborhood of the end 6 of the partition wall 2 and near the bottom.
