摘要
PURPOSE: Provided is a sewage plant combining a biofilm process and a sequencing batch process so as to remove organic substance as well as nitrogen and phosphorous contained in sewage with high efficiency. CONSTITUTION: The plant comprises a first settling tank(21), a flow equalization basin(22), a first biofilm sequencing batch reactor(23), a second biofilm sequencing batch reactor(24), an aeration tank(25), a second settling tank(26), wherein the first biofilm sequencing batch reactor(23) and the second biofilm sequencing batch reactor(24) are connected to the each other at the bottom thereof, a diffuser(28) connected to an external air pressure generation device, an underwater pump(27) operating under no air condition, a transportation pipe(29) for transporting wastewater and sludge to the aeration tank(25) after reaction is completed.
