Description
본 발명은 광촉매반응기와 수처리용 바이오필터시스템을 조합하고, 조합 시너지효과를 극대화하기 위하여 광촉매반응기에서 처리된 하폐수를 수처리용 바이오필터시스템으로 반송시키는 것을 특징으로 하는 도 1과 같은 유기 또는 무기화합물이나 악취오염원을 함유한 도시하수, 염색폐수 또는 산업폐수를 포함하는 하폐수 처리 방법 및 장치에 관한 것이다. 도시하수, 염색폐수 또는 산업폐수를 포함하는 하폐수 원수는 수처리용 바이오필터를 통과하고 생물학적 처리된 하폐수는 광촉매를 담지한 UV(또는 VIS-)/광촉매반응공정에서 살균 및 오염원 처리되어 배출된다. 배출되지 않는 UV(또는 VIS-)/광촉매반응공정 처리수는 광촉매반응기와 바이오필터시스템으로 이루어진 혼합공정시스템의 시너지를 극대화하기 위하여 하폐수 원수가 처리되는 수처리용 바이오필터로 반송된다. 이와 같이 UV(또는 VIS-)/광촉매반응공정에서 처리된 하폐수를 수처리용 바이오필터로 반송함으로써 난분해성물질 산화분해에 대한 조합 시너지효과를 극대화할 수 있다.The present invention combines a photocatalytic reactor with a water treatment biofilter system, and in order to maximize the combined synergy effect, the organic or inorganic compound as shown in FIG. 1, wherein the wastewater treated in the photocatalytic reactor is returned to the water treatment biofilter system. The present invention relates to wastewater treatment methods and apparatus including municipal sewage, dyeing wastewater or industrial wastewater containing malodorous pollution sources. Raw wastewater, including municipal wastewater, dyed wastewater or industrial wastewater, passes through a biofilter for water treatment, and biologically treated wastewater is discharged after being sterilized and polluted in a UV (or VIS-) / photocatalytic reaction process carrying a photocatalyst. Non-emitted UV (or VIS-) / photocatalytic process water is returned to the biofilter for water treatment where raw sewage water is treated to maximize the synergy of the combined process system consisting of the photocatalytic reactor and the biofilter system. As described above, by returning the wastewater treated in the UV (or VIS-) / photocatalytic reaction process to the biofilter for water treatment, the combined synergy effect on the oxidative decomposition of the hardly decomposable substance can be maximized.
염색 폐수 처리는 물리적화학적생물학적 방법을 이용할 수 있는데, 흡착, 침전, 산화, 막분리 등의 물리적화학적 방법은 빠르게 처리할 수 있는 장점이 있지만, 고가의 처리시설과 과다한 유지비가 필요하며, 특히 화학적 처리의 경우 화학약품의 사용에 따른 2차 오염 문제가 있다. 기존의 염색폐수 처리시설은 대부분이 물리화학적 처리공정과 생물학적 처리공정을 복합적으로 사용하고 있다. 이것은 하나의 단위공정으로는 염색폐수를 적절한 수준으로 처리할 수 없기 때문이다. 이로 인해 많은 비용이 낭비되고 있는 실정이다. 따라서 전술한 난분해성물질을 분해하기 위하여 환경 친화적이며 비용이 저렴한 생물학적 처리기술과 AOP(Advanced Oxidation Processes)기술을 접목한 혼합공정 기술개발의 중요성이 증대되고 있다.Dyeing wastewater treatment can use physicochemical and biological methods, but physicochemical methods such as adsorption, precipitation, oxidation, and membrane separation have advantages in that they can be treated quickly, but require expensive treatment facilities and excessive maintenance costs, especially chemical treatment. In this case, there is a secondary pollution problem due to the use of chemicals. Most existing dyeing wastewater treatment facilities use a combination of physicochemical and biological processes. This is because dyeing wastewater cannot be treated at an appropriate level in one unit process. This wastes a lot of money. Therefore, in order to decompose the above hardly decomposable substances, the importance of the development of a mixed process technology incorporating environmentally friendly and inexpensive biological treatment technology and AOP (Advanced Oxidation Processes) technology is increasing.
오존이 용존유기물의 오직 일부를 산화시켜서 용존유기물의 완전한 무기물화나 생분해성유기물화는 기대할 수가 없다는 것은 잘 알려져 있다. 이것이 다단계의 오존-생물학적처리가 용존유기물의 제거에 매우 제한적이라는 것에 대한 이유가 될 수 있다. AOP는 오존에 분해되지 않는 유기오염물의 분해에 효과적이다. AOP공정 중에서 생성되는 OH 라디칼은 오염된 물에 존재하는 거의 모든 유기화합물을 잘 분해시킨다. 거기에다 OH 라디칼은 용존유기물의 큰 분자를 분해시켜서 생분해성 유기물을 생성시킨다. 이와 같이 오존처리와는 다르게 AOP(Advanced Oxidation Processes)는 미생물에 난분해성인 용존유기물을 발생된 OH 라디칼로 분해하여 작은 BDOC(Biologically degradable organic compound)를 생성시켜서 미생물 처리가 용이하도록 하여준다고 보고되고 있다. Lim et al.[Korean Journal of Chemical Engineering, 22, 70(2005)]은 UV/광촉매 반응기와 액상의 미생물막을 충전한 바이오필터로 이루어진 hybrid시스템의 비정상상태에서 에탄올과 톨루엔을 함유한 폐가스를 처리하는 거동을 관찰하였는데, 톨루엔과 에탄올에 대한 최대 elimination capacity 증가분에 대한 UV/광촉매반응기의 직접적인 공헌도는 각각 17.5%와 21.5%이었고 간접적인 공헌도(hybrid시스템의 synergy효과)는 각각 82.5%화 78.5%이었다고 보고하였다. 따라서 UV/광촉매산화/바이오필터 hybrid시스템 공정의 synergy효과에 의한 톨루엔 및 에탄올에 대한 elimination capacity 증가분은 UV/광촉매반응기의 직접적인 공헌도의 각각 약 400%에 달하였다.It is well known that ozone oxidizes only a portion of dissolved organics, so that complete inorganic or biodegradable organics cannot be expected. This may be the reason for the multi-step ozone-biological treatment being very limited in the removal of dissolved organics. AOP is effective for the decomposition of organic pollutants that are not decomposed by ozone. The OH radicals generated during the AOP process decompose almost all organic compounds present in contaminated water. In addition, OH radicals break down large molecules of dissolved organics to produce biodegradable organics. As such, unlike ozone treatment, AOP (Advanced Oxidation Processes) is reported to make microbiologically degradable organic compounds (BDOCs) easier by decomposing dissolved organic matter decomposed into microorganisms into OH radicals. . Lim et al. [Korean Journal of Chemical Engineering , 22 , 70 (2005), observed the behavior of treating waste gas containing ethanol and toluene in the abnormal state of a hybrid system consisting of a UV / photocatalytic reactor and a biofilter filled with a liquid microbial membrane. The direct contributions of the UV / photocatalytic reactor to the maximum increase in elimination capacity were 17.5% and 21.5%, respectively, and the indirect contributions (synergy effect of the hybrid system) were 82.5% and 78.5%, respectively. Therefore, the increase in elimination capacity for toluene and ethanol by synergy effect of UV / photocatalytic oxidation / biofilter hybrid system process was about 400% of the direct contribution of UV / photocatalytic reactor, respectively.
염색폐수 처리에 대한 기존 연구동향을 보면 미생물 또는 AOP를 단독으로 각각 이용하여 특정 단일염료를 포함한 합성폐수를 처리한 연구가 거의 대부분이다. 또한 특정 단일염료나 단일오염물 제거에 대한 연구결과를 현장의 종합염색폐수에 적용하기에는 미흡한 점이 많음에도 불구하고, 염색폐수 처리를 위해 개발한 신기술들은 합성폐수를 사용한 연구결과들이 대부분이며, 실제 종합염색폐수 처리에 대한 적용사례는 미비한 편이고 그에 대한 연구결과도 성공적이지 않다. 예를 들어서 생물학적 염색폐수 처리에 대한 기존 연구동향을 보면 특정 미생물을 이용하여 염색폐수에 포함된 오염물질중 단일성분을 처리한 연구가 많은데 특히 동일한 화학적 구조를 가진 염료들을 미생물로 처리한 연구가 가장 많으며, 미생물을 이용하여 EG, PVA를 처리한 연구가 일부 보고된 바 있다. 그러나 특정 미생물을 이용한 염료나 기타 오염물 제거에 대한 연구결과는 현장에 적용하기에는 미흡한 점이 많으며, 기존의 생물학적 염색폐수 처리방법에 대한 최적화는 처리효율을 다소 개선할 수 있으나 근본적으로 처리효율을 극대화하기에는 한계가 있다. The existing research trends on the treatment of dye wastewater are almost all studies of treating synthetic wastewater containing a specific single dye using microorganism or AOP alone. In addition, despite the fact that the results of research on the removal of specific single dyes or single contaminants are inadequate to be applied to the field of synthetic dye wastewater, the new technologies developed for the treatment of dye wastewater are mostly the results of research using synthetic wastewater. The application of wastewater treatment is inadequate and the results of this study are not successful. For example, in the existing research trends on the treatment of biological dye wastewater, there are many studies in which a single microorganism is used to treat a single component among the pollutants contained in the dye wastewater. Many studies have been reported to treat EG and PVA using microorganisms. However, the results of research on the removal of dyes and other contaminants using specific microorganisms are inadequate for the field application, and the optimization of existing biological dye wastewater treatment methods can improve the treatment efficiency somewhat, but it is fundamentally limited to maximize the treatment efficiency. There is.
