WASTEWATER TREATMENT APPARATUS AND SEQUENCING BATCH REACTOR SYSTEM USING THE SAME

摘要

PURPOSE: A wastewater treatment apparatus and sequencing batch reactor system using the same which can remove nitrogen and phosphorus in wastewater effectively is provided. CONSTITUTION: The apparatus comprises a reactor(1); a pump(2); a plural ejectors(9) which are installed near the bottom of the reactor to prevent sludge sedimentation by blowing air upward; an ejector connection pipeline(4) for agitation which connects the pump and the ejectors; a plural ejectors(5) which are installed below the surface level of the reactor to save power required to aeration by decreasing the depth of aeration; and an ejector connection pipeline(6) for aeration.
