AN ANOXIC/ANAEROBIC/AEROBIC PROCESS FOR THE REMOVAL OF NITROGEN AND PHOSPHORUS FORM WASTEWATER

摘要

In this paper, anoxic/anaerobic/aerobic processes were developedto remove nitrogen and phosphorus from wastewater more efficiently.Laboratory experiments were conducted, and the results demonstratedthat the innovative combined processes have a much higher efficiencyin the removal of nitrogen and phosphorus than the commonly usedanaerobic/anoxic/aerobic processes. The removal rates of nitrogen andphosphorus can be increased by about 50/100 on Average.
