CONTACT REACTION TOWER WITH INTERNAL CIRCULATION OZONE USED IN INDUSTRIAL WASTEWATER ADVANCED TREATMENT

摘要

A contact reaction tower with internal circulation ozone used in industrial wastewater advanced treatment comprises a central cylinder (2) and an outer cylinder (1). The central cylinder (2) is internally provided with lift pipes (5) and a water inlet pipe (8). Reflux holes (13) are located on the wall of the central cylinder (2). The water is circulated between the central cylinder (2) and the outer cylinder (1) by the lift pipes (5), the water inlet pipe (8) and the reflux holes (13). The whole tower is sealed up and equipped with a gas guiding pipe (17) on its top. The reaction tower can make the gas and the water contact and mix sufficiently and ensure the quality of the outlet water and easy adjustment and control.
