ADVANCED SEWAGE TREATMENT SYSTEM BY PARTY WALL IN MBR USING SND

摘要

PURPOSE: An advanced sewage treating system based on a separator in a simultaneous nitrification and denitrfication(SND)-based membrane bio reactor(MBR) is provided to simultaneously eliminate organic materials, nitrogen, and phosphorus from sewage by securing an anaerobic region in the MBR. CONSTITUTION: An MBR module(200) is installed at one side of an MBR(100), and the MBR includes a dissolved oxygen(DO) motor(600) for DO. A blower(800) supplies oxygen to the MBR module. An introducing pump(500) introduces introducing water to the lower side of the MBR. A discharging water container receives discharging water from the MBR based on a pressure gauge(400) and a suction pump(502). A pump(503) reversely introduces the discharging water from the discharging water container to the MBR. Another pump(501) circulates the introducing water b being installed at the lower side of the MBR module. A partition(900) is installed at one side of the DO motor. One or more stirrers(300) are installed at the MBR module.
