摘要
A cesspit for domestic sewage is a stationary cylindrical tank with the rotatable inner tank which is divided into four segments. Each segment has a clearance manhole near the bottom which can be aligned by rotation of the inner tank with a clearance manhole in the outer tank. A central tube, passing to the bottom of the inner tank, where perforated branch tubes protrude upward at an angle, is used for the admission of air. This plant works continuously and can be expanded for use by several persons by adding sections to the top.
