METHODS AND APPARATUS FOR NITROGEN REMOVAL FROM WASTEWATER

摘要

The present invention is directed to equipment, systems and methods for the biological removal of nitrogen from wastewater. The ammonium removal processes disclosed herein can be used in both batch and continuous flow biological reactors with real time control of nitrogen loading to effectively cultivate ammonium oxidizing bacteria alone, as well as in a mixture of ammonium oxidizing bacteria with anaerobic ammonium oxidizing bacteria in a single bioreactor. Both batch and continuous flow biological reactors have a mean of separating solids retention time (SRT) of suspended nitrifying biomass from suspended anammox biomass.
