A SUBMERGED MEMBRANE BIO REACTOR EASILLY RESPOND TO LOAD REGULATION AND METHOD OF WASTEWATER TREATMENT USING THE SAME

摘要

PURPOSE: A submerged membrane bio reactor and a method for processing sewage using the same are provided to maintain the capability of a sewage processing process by controlling the concentration of dissolved oxygen in an aerobic bath. CONSTITUTION: A membrane filter(630) is installed in an aerobic bath or a membrane filtering bath(610) in order to separate overlaying water. A membrane cleaning diffuser(640) cleans the membrane of the membrane filter by being installed at the lower side of the membrane filter. A cover(650) is installed at the upper side of the membrane filter. A gas circulating pipe(660) connects the cover and the entrance of a membrane cleaning blower(620). An air pipe connects the membrane cleaning diffuser and the exit of the membrane cleaning blower.
