Description

생물막 오염 저해용 카트리지 필터, 이의 제조방법 및 이를 이용한 막여과 수처리장치Cartridge filter for inhibiting biofilm contamination, its manufacturing method and membrane filtration water treatment device using the same
본 발명은 생물막 오염 저해용 카트리지 필터, 이의 제조방법 및 이를 이용한 분리막의 수처리 방법에 관한 것으로서, 보다 상세하게는 막여과 수처리장치의 처리수를 전처리하는 생물막 오염 저해용 카트리지 필터, 이의 제조방법 및 이를 이용한 분리막의 수처리 방법에 관한 것이다.The present invention relates to a cartridge filter for inhibiting biofilm contamination, a method for manufacturing the same, and a water treatment method for a separation membrane using the same, and more particularly, a filter for inhibiting biofilm contamination for pretreating the treated water of a membrane filtration water treatment apparatus, and a method for manufacturing the same. It relates to a water treatment method of the separator used.
최근 양질의 처리수를 얻기 위해 다양한 수처리 공정에 분리막 공정이 적용되고 있다. 생물학적 수처리 반응조에 막분리 공정을 결합한 분리막 생물반응조(Membrane bioreactor, MBR) 공정이나, 물리화학적 전처리공정에 결합된 통상의 분리막 수처리 공정 및 고도 수처리를 위한 나노여과 및 역삼투막 공정 등이 널리 적용되고 있다.Recently, membrane processes have been applied to various water treatment processes to obtain high quality treated water. Membrane bioreactor (MBR) process that combines membrane separation process with biological water treatment reactor, conventional membrane water treatment process combined with physicochemical pretreatment process, nanofiltration and reverse osmosis membrane process for advanced water treatment, etc. are widely applied.
그러나, 분리막 공정의 운전이 진행됨에 따라 반응조 내부에 존재하는 박테리아, 곰팡이, 조류(algae) 등과 같은 미생물들이 분리막 표면에서 부착성장(attached growth)을 시작하여 최종적으로는 수십 마이크로미터 내외의 두께를 가지는 생물막(biofilm)을 형성하며 분리막의 표면에 성장하게 된다. However, as the operation of the membrane process proceeds, microorganisms such as bacteria, fungi, algae, etc. present in the reaction tank start attached growth on the surface of the membrane and finally have a thickness of about several tens of micrometers. It forms a biofilm and grows on the surface of the separator.
이러한 분리막의 표면에 생물막이 형성되어 오염되는 현상은 분리막 생물반응조 공정 뿐만 아니라, 통상의 분리막 수처리 공정 또는 나노여과 및 역삼투막 공정의 고도 수처리 공정에서도 흔히 발견되는 현상이다. The phenomenon in which biofilms are formed and contaminated on the surface of the separator is a phenomenon commonly found not only in a membrane bioreactor process but also in a conventional membrane water treatment process or an advanced water treatment process of nanofiltration and reverse osmosis membrane processes.
이러한 생물막은 분리막의 여과 성능을 저하시키는 여과 저항(filtration resistance)으로 작용하는 생물막 오염(membrane biofouling)의 문제를 유발하며, 최종적으로는 투수도의 감소, 분리막의 세정주기 및 수명 단축, 여과에 필요한 에너지 소비량 증가 등 분리막 공정의 여과 성능을 저하시킴으로써 수처리용 분리막 공정의 경제성을 악화시키게 되는 문제를 유발하게 된다.Such biofilms cause the problem of membrane biofouling, which acts as a filtration resistance that degrades the filtration performance of the membrane. Finally, the biomembrane is required to reduce water permeability, to shorten the cleaning cycle and life of the membrane, and to filter the membrane. Degradation of the filtration performance of the membrane process, such as increased energy consumption, causes a problem that worsens the economics of the membrane process for water treatment.
또한, 역삼투막(RO막) 여과공정에서 막오염이 발생되면, 플럭스(Flux)의 감소에 따른 공정효율 저하와 막교체에 따른 운영비가 증가하게 되고, 특히 막오염의 주요 인자 중 미생물의 경우 소량만 유입되어도 막표면 흡착 후, 성장하며 미생물막을 형성하여 다른 막 오염인자 보다 더 큰 막오염을 유발하는 문제도 있었다. In addition, when membrane fouling occurs in the reverse osmosis membrane (RO membrane) filtration process, process efficiency decreases due to a decrease in flux and operating cost increases due to membrane replacement, and in particular, only a small amount of microorganism is a major factor of membrane fouling. Even if it was introduced, there was a problem that the membrane surface adsorbed and then grown to form a microbial membrane, causing more membrane contamination than other membrane contamination factors.
이와 같은 문제 해결을 위한 종래의 막여과 수처리장치로는, 폭기와 같은 물리적 방법, 및 고분자 응집 등의 약품 투입에 의한 화학적 방법이 제시되고 있으나, 생물막이 완전하게 제거되지 않아 문제점이 그대로 남아 있는 실정이다.Conventional membrane filtration water treatment apparatus for solving such a problem, physical methods such as aeration, and chemical methods such as the introduction of chemicals such as polymer agglomeration has been proposed, but the problem remains as the biofilm is not completely removed. to be.
