Abstract: A wastewater treatment system may use recycle water to apply an anaerobic ammonium oxidation (ANAMMOX) process to a water treatment process (mainstream treatment process) and to stably supply nitrite required for an ANAMMOX. By applying the ANAMMOX process, nitrogen and phosphorus may be simultaneously treated in the water treatment process, and recycle water may be used as a source of nitrite for ANAMMOX, thereby reducing wastewater treatment costs and pollutant loading.
