Summary:The present invention relates to a contamination-resistant surface modified membrane and a membrane filtration wastewater treatment system using the same. Provided is the membrane filtration wastewater treatment system using the contamination-resistant surface modified membrane, the system comprising: a storage unit which is equipped with a screen, and which deposits sludge by using gravity; an activated sludge part which includes a lower stage and an upper stage, in which the upper stage receives upper wastewater of influent water stored in the lower stage, which treats the influence water by using microorganisms, and in which inflow of the wastewater to the upper stage is performed by a screw device; a transfer part which transfers deposits, present in a lower region of the treated water, to the activated sludge part, and which discharges upper treated water; a membrane separation part which introduces the treated water into a plurality of module housings, in which interiors of the module housings are composed of surface-modified separation membranes, and which includes an influent water transfer conduit configured to discharge water, passing through the separation membrane, to a passed water discharge conduit and to discharge treated water, not passing through the separation membrane, to the transfer part; and a sterilization part which sterilizes the treated water by radiating ultraviolet rays onto the treated water by means of a light source means. A plurality of sludge deposition steps using gravity are included as a preprocessing process for a membrane separation process and an activated sludge process is employed, and thus membrane contamination can be reduced and maintenance, repair and management can be facilitated. Surface modification is performed by using an amphiphilic separation membrane having both hydrophilicity and hydrophobicity, and thus contamination of the separation membrane can be reduced, thereby increasing lifespan and thus increasing economic efficiency. A water treatment process is simplified into five steps, and thus economic efficiency can be increased. Moreover, the system can be manufactured in various sizes, including a large size and a small size. 본 발명은 양친매성막을 이용한 표면개질 내오염성 분리막 및 이를 이용한 막여과 하폐수 처리 시스템으로, 보다 상세하게는 스크린이 시설되고, 중력에 의하여 슬러지를 침전시키는 저장부, 하부단과 상부단으로 구성되고, 상기 상부단은 하부단에 저장되어 있는 유입수의 상부영역 폐수를 유입시켜 미생물에 의하여 수처리하며, 상부단으로 폐수의 유입은 스크루장치에 의하여 실시되는 활성슬러지부, 처리수의 하부영역에 침전물을 활성슬러지부로 반송시키고, 상부영역의 처리수는 배출하는 반송부, 복수개의 모듈 하우징 내부로 처리수를 주입시키고, 모듈하우징 내부는 표면개질된 분리막으로 이루어져 있으며, 상기 분리막으로 투과된 투과수는 투과수 배출관, 투과되지 못한 처리수를 반송부로 배출하는 유입수 반송관을 포함하여 이루어지는 막분리부, 처리수를 광원수단으로 자외선을 조사하여 살균처리하는 살균부로 이루어진 표면개질 내오염성 분리막 및 이를 이요한 막여과 하폐수 처리 시스템에 관한 것으로 막분리공정 전처리 과정으로 중력을 이용한 슬러지 침전 과정을 복수개 포함하고, 활성슬러지법을 실시하여 막오염을 줄이고, 유지 및 관리를 편리하게 실시하고, 친수성 및 소수성을 가지는 양친매성 분리막을 사용하여 표면개질함으로써 분리막 오염이 저감되어 사용수명이 늘어나 경제성이 높으며, 수처리 과정을 다섯개의 공정으로 간소화하여 경제성을 높이고, 그 구성을 대형 또는 소형으로 제작이 가능하다는 장점을 가지고 있다.
