Abstract
In this paper, anoxic/anaerobic/aerobic processes were developed to remove nitrogen and phosphorus from wastewater more efficiently. Laboratory experiments were conducted, and the results demonstrated that the innovative combined processes have a much higher efficiency in the removal of nitrogen and phosphorus than the commonly used anaerobic/anoxic/aerobic processes. The removal rates of nitrogen and phosphorus can be increased by about 50% on average. In addition, the new combination can also simplify the process operation of sludge cycles.
