본 발명은 상수원수 전처리 및 고도정수처리를 위한 생물막 여과와 막분리 여과장치에 관한 것으로 상수원수(표류수 또는 지하수)의 수질을 생물막 여과공정으로 1,2급수로 개선하여 막의 오염부하량을 감소시켜 막수명 연장을 가능하게 하고, 막분리 여과를 통하여 고도의 정수처리를 함으로써 경제적이며 맛있고 안전한 음용수 생산이라는 환경기술적인 문제점을 해결하려는데 있다.The present invention relates to a biofilm filtration and membrane separation filtration device for the pre-treatment and advanced water treatment of purified water to improve the water quality of purified water (drift or groundwater) to 1,2 grade water by the biofilm filtration process to reduce the fouling load of the membrane It is intended to solve the environmental and technical problems of economical, delicious and safe drinking water production by enabling membrane life extension and by performing highly purified water treatment through membrane filtration.

자연유기물질 NOM은 정수처리공정에서 발생하는 소독부산물(DBPS ; THMS, HAAS 등)의 전구물질이며, 고도정수처리공정으로 새로이 부각되고 있는 막여과 공정에 있어서는 막오염(fouling)을 유발시키는 주요오염원이기도 하다. D/DBP Rule (EPA, US)의 Phase Ⅱ (2001년부터 시행)에 따르면 THMS의 경우 현재의 80㎍/L에서 40㎍/L로, HAAS(HAA5)의 경우 60㎍/L에서 30㎍/L로 더욱 강화 될 전망이다. 또한 기존의 응집·침전+급속모래여과지를 이용한 정수처리시스템은 약품사용과 침전슬러지의 처리에 따른 비용 문제, 약품주입에 따른 부산물생성 문제, 응집·침전지 사용에 의한 소요부지면적의 문제, 공정의 세균, 바이러스의 유출에 의한 감염 문제, 염소소독에 의한 THMs과 같은 소독부산물의 생성 문제, 소독부산물의 전구물질인 NOM의 제거효율 문제 등으로 안전하고 경제적인 정수장 운영이 어려운 실정이다.Natural organic substance NOM is a precursor of disinfection by-products (DBP S; THM S , HAA S, etc.) generated in the water treatment process, and causes fouling in the membrane filtration process newly emerging as a high water treatment process. It is also a major source of pollution. According to the Phase II of the D / DBP Rule (EPA, US) (since 2001), THM S is now 40 µg / L at 80 µg / L and 30 µs at 60 µg / L for HAA S (HAA5). It is expected to be further strengthened to μg / L. In addition, the existing water treatment system using the flocculation sedimentation + rapid sand filter has the cost of using the chemicals and the treatment of sediment sludge, the generation of by-products due to the injection of the chemicals, the problem of the required area due to the use of the flocculation and sedimentation, and the process. It is difficult to operate a safe and economical water treatment plant due to the problem of infection by leakage of bacteria and viruses, generation of disinfection by-products such as THMs by chlorine disinfection, and removal efficiency of NOM, a precursor of disinfection by-products.

막여과 공정의 전처리 공정으로 응집, 응집-침전, 모래여과 등 여러 형태로 막여과 공정의 전처리에 대한 연구가 활발히 진행 중에 있지만 외국의 사례와 비교해 볼 때 생물막여과를 이용한 막여과의 전처리 공정에 대한 국내의 연구 사례는 아직까지 발표되고 있지 않은 실정이다.
The pretreatment process of membrane filtration is being actively researched for the pretreatment of membrane filtration in various forms such as coagulation, flocculation-sedimentation and sand filtration.However, compared with foreign cases, the pretreatment of membrane filtration using biofilm filtration Domestic research cases have not been published yet.

본 발명은 상기와 같은 문제점을 해결하기 위해 생물막 여과와 막분리를 이용한 고도정수처리 장치를 발명한 것으로,In order to solve the above problems, the present invention invents an advanced water treatment apparatus using biofilm filtration and membrane separation.

We want to provide a life extension.

둘째, 막분리 여과를 통하여 기존의 급속모래여과법에 의한 정수처리에서 얻기 힘들었던 수질인 탁도 0.1NTU이하, 크기 2㎛ 입자수 20개 이하, 맛·냄새 물질(2-MIB, Geosmin)의 원인인 조류의 제거가 가능하여 초고도의 음용수 수질을 제공하고자 한다.Second, through membrane separation filtration, the turbidity of water, which is difficult to obtain by conventional rapid sand filtration, is less than 0.1 NTU, the number of particles having a size of 2㎛ 2㎛ 20 or less, algae that causes taste and smell substances (2-MIB, Geosmin) It can be removed to provide ultra-high drinking water quality.

셋째, 생물막 여과와 막분리 여과를 이용한 고도정수처리 장치를 통하여 기존 급속모래여과법에 의한 정수시스템을 간략화 하고, 설치면적 축소, 슬러지발생량 감소, 동력비 감소를 통하여 경제적인 정수기술을 제공하고자 한다.
Third, through the advanced water treatment system using biofilm filtration and membrane separation filtration, we will simplify the existing water purification system by the rapid sand filtration method, and provide economic water purification technology by reducing the installation area, reducing the sludge generation, and reducing the power cost.
