The present invention relates to a waste water treatment device equipped with a membrane module and a method therefor. More specifically, the present invention relates to a waste water treatment device equipped with a membrane module and a method therefor, wherein a screen tank, anaerobic tank, oxygen-free tank, MBR tank, and SDR tank are sequentially disposed in the waste water treatment device. The membrane module is included in the MBR tank, and an aerator part is equipped on the circumference of the membrane module, wherein a plurality of vertical supply pipes and horizontal supply pipes are disposed to be separated at a particular distance from the membrane module and are coupled in a grid shape in order to form the aerator part. Therefore, the amount of dissolved oxygen is increased, and cake layers accumulated on the membrane module are effectively removed. The waste water treatment device equipped with a membrane module of the present invention comprises: a screen tank which filters inert matter and suspended material from waste water that is fed through a feeding pipe equipped on one side thereof; an anaerobic tank which is connected with the screen tank and is equipped with an underwater agitator so as to remove phosphorous from treated water that is treated in and transferred from the screen tank; an oxygen-free tank which is connected with the anaerobic tank and is equipped with an underwater agitator so as to denitrify the treated water that is transferred from the anaerobic tank; an MBR tank which is connected with the oxygen-free tank and is equipped with a membrane module so as to remove residual organic materials from the treated water that is fed from the oxygen-free tank and separate solid and liquid from water and sludge; an SDR tank which is connected with the MBR tank so as to perform sulfur denitrification on the treated water that is fed from the MBR tank; and a discharge pipe which discharges the treated water that is filtered from the SDR tank. On the circumference of the membrane module, an aerator part is formed, wherein a plurality of vertical supply pipes and horizontal supply pipes are disposed to be separated at a particular distance from the membrane module and are coupled in a grid shape in order to form the aerator part, and multiple air nozzles are equipped on each side surface of the aerator part. |
