The municipal sewage is mainly treated in this plant. Its water quality is more complicated.According to the demands for the design, the contents of nitrogen and phosphorus are high in the water quality of this project .So they should be dealed with,while BOD5 and SS are cleared. The plant adopts the major technology process for Carrousel Oxidation Ditch and Gravitate Thickeners. The technology has characterize for short-period process, high efficiency, steady water quality, small rest solids and low fees for the construction and operation and so on. And what’s more, it will be operated and managed in a convenient manner. So the comprehensive craft exists extensive adaptability and is totally suitable for the practical purpose of the originally design.
