MBR WATSTEWATER TREATMENT TECHNOLOGY APPLIED IN REFINERY SEWAGE

Membrane bioreactor(MBR)is a new wastewater treatment process combined with membrane technology and sewage biological treatment technology,which has been applied in industrial wastewater treatment in recent years.A new MBR plant was jointly built in Jinling Petrochemical Branch by Jinling Petrochemical Branch and Nuowei Environment and Safety Engineering Technology Co.Ltd of Guangzhou,with capacity of 250t/hr and was put into operation in November 2005.So far the plant has continuously been running over half a year,COD,oil,sulfur,phenol,ammonia nitrogen and turbidity removals still stabilize on 80%,60%,100%,98%,90%,99% respectively.It provides a condition for sewage to be reused.
