SEWAGE AND WASTEWATER TREATING METHOD AND SYSTEM THE SAME

摘要

A method and an apparatus for treating sewage/wastewater are provided to chemically cohere and remove phosphorous by dipping an iron plate into a reactor and eluting iron from the iron plate through electrolysis. A sewage/wastewater treatment apparatus comprises: a flow equalization tank(100) agitating sewage/wastewater flown in, controlling flux fluctuations of the sewage/wastewater, and discharging the sewage/wastewater; a batch reactor(200) removing phosphorous using iron compounds generated from an electrolyzer dipped into the sewage/wastewater, removing nitrogen and organic matters by nitrification and denitrification, discharging a settled sludge layer of a bottom layer to a sludge discharge pipe by the sedimentation process, and discharging supernatant of a top layer using a floating decanter; a sludge concentrating and storing tank(400) discharging the settled sludge layer to the outside or the flow equalization tank after temporarily storing the settled sludge layer flown in through the sludge discharge pipe; and a disinfection and discharge water tank(300) discharging the supernatant after disinfecting the supernatant flown in through the floating decanter.
