Advanced Sewage treatment system with continuous single bioreactor and reverse osmosis membrane and reverse osmosis concentrated water treatment system

摘要

Disclosed is an excess sludge treatment system which secures the stable treated water quality regardless of water temperature by applying a membrane and a reverse osmosis device for processing treated water in which the solid and liquid are separated in a continuous single bioreactor for allowing the reuse of water. In the excess sludge treatment system, the chemical oxygen demand (NBDCOD) and refractory nitrogen which cannot be biodegraded are removed from concentrated water generated during reverse osmosis by using excess sludge, so that the maintenance costs such as drug costs and power costs can be reduced, and the size of a structure is simplified while making a treatment facility more stable.
