MEMBRANE WASTEWATER TREATMENT SYSTEM AND METHOD FOR HIGH ENERGY EFFICIENCY, HIGH FLOW CAPICITY, LOW OPERATING COST, AUTOMATED SCUM AND FOAM REMOVAL / DESTRUCTION AND CONVERSION METHOD THEREOF FROM A CONSTANT LEVEL SEQUENCING BATCH REACTOR PROCESS

摘要

Disclosed are a system and a method for treating sewage and wastewater. The present invention relates to a system and a method for membrane treatment of sewage and wastewater, capable of removing pollutants included in sewage and wastewater through a process for advanced biological treatment using a constant level continuous flow sequencing batch reactor (CSBR^TM); a process conversion method into a membrane bioreactor having high flux, high energy efficiency and low operating costs; and a system for automated maintenance and removal of scum and foam.
