Abstract
An integrated oxidation ditch comprises a number of oval channels. There are two or more circular zones in the central island of the oxidation ditch, wherein, the two circular zones are tangential to the inner wall or share the inner wall with an adjacent channel. Wastewater of different zones is connected with others. The center island is used sufficiently in the oxidation ditch and all the channels and the deposition zone or the deposition zone and an anaerobic zone, inner/outer re-circulation zone are integrated together. So the oxidation ditch improves space utilization efficiency and reduces the land and cost.
