WASTEWATER TREATMENT SYSTEM USING MULTI SEQUENCING BATCH REACTOR (SBR)

摘要

PURPOSE: A wastewater treatment system which operates adsorption reactor, nitrification reactor and denitrification reactor separately by using multi SBR is provided to remove organic substances, nitrogen and phosphorus effectively. CONSTITUTION: The multi SBR comprises an anaerobic contact tank(1), a nitrification reactor(2) and an intermittent aeration reactor(3). Wastewater reacts with return sludge in anaerobic contact tank and nitrification react of wastewater is performed in the nitrification reactor where return sludge is used as organic carbon source for denitrification and dephosphorization reacts.
