摘要
The present invention relates to a method for treatment of wastewater. More particularly, the methods of the present invention are designed for the biological removal from wastewater of contamination in the form of insoluble suspended solids and soluble and insoluble organic and inorganic material, including nitrogen and phosphorus nutrients. A wastewater treatment process is described, which process is a hybrid continuous flow, cyclic operating, substantially constant level, activated sludge process with a symmetric functional cycle. In this functional cycle each compartment of a reactor is subsequently in a different functional phases, which functional phases are continuously separated: phase 1, phase 2, phase 3, phase 4, phase 1, phase 2, phase 3, phase 4, etc... The symmetric functional cycle allows for symmetric (equal) influent distribution and therefore symmetric sludge and oxygen demand distribution.
