Sewage treatment plant contg. well-type aeration basin - integrated with final settling tank for compact sewage treatment

摘要

A plant for the treatment of sewage consists of a well-type aeration basin and a final settling tank is arranged as an integral unit of the former and surrounds it near the surface. The aeration well is divided into a downflow section and an upflow section, with the latter discharging into the final settling tank. This saves the space and the piping required for a final settling tank, which is separate from the aeration basin.
