ADVANCED WASTEWATER TREATMENT MBR(MEMBRANE BIO-REACTOR) PROCESS FOR REDUCING MEMBRANE FOULING

摘要

The present invention relates to an advanced wastewater treatment apparatus for reducing membrane fouling and an operation method thereof and, more specifically, to an advanced wastewater treatment apparatus for reducing membrane fouling, which is capable of reducing membrane fouling by injecting particulate materials with air into a membrane separation tank and forcing the air and the particulate materials to collide with a membrane at the same time, and an operation method thereof. The present invention relates to an advanced sewage treatment apparatus for treating sewage, comprising: an anaerobic tank for releasing phosphorus of the sewage and removing organic materials of the sewage; an anoxic tank for denitrifying the sewage and removing organic materials; a membrane separation tank which includes a membrane for the nitrification, organic material oxidation, and solid liquid separation of the sewage; an aeration means for injecting air in order to force the air to collide with the membrane of the membrane separation tank; and a particulate material injection means for injecting particulate materials capable of colliding with the membrane along with the air injected by the aeration means in the membrane separation tank.
