METHOD FOR HIGH CLASS TREATMENT OF WASTEWATER USING GAS PERMEABLE MEMBRANE-ATTACHED BIOFILM

摘要

PURPOSE: A wastewater processing method using a gas permeable membrane is provided to improve efficiency of a wastewater processing process and to reduce costs for supplying gas regardless of organic materials in wastewater. CONSTITUTION: A wastewater processing method using a gas permeable membrane includes the following steps: removing and decomposing organic compounds or nitrogen compounds with a biofilm while maintaining an aerobic condition; removing the organic compounds or the nitrogen compounds while maintaining an anaerobic condition; and successively performing above processes. A gas-permeable membrane is used in each process.
