Description

고농도 폐수의 생물학적 처리수에 대한 고도처리 방법 {Method for enhanced treatment from biological treatment effluent of high concentrated wastewater}Method for enhanced treatment from biological treatment effluent of high concentrated wastewater}

본 발명은 축산ㆍ분뇨ㆍ산업폐수와 같은 고농도 폐수를 생물학적으로 처리한 유출수를 고도처리하는 방법에 관한 것이다.The present invention relates to a method for advanced treatment of effluents biologically treated with high concentration wastewater such as livestock, manure and industrial wastewater.

일반적으로 고농도 폐수처리를 위한 공정은 전처리, 생물학적 처리, 및 고도처리로 구성되어 있다. 전처리는 협잡물과 SS(Suspended Solid)를 제거하는 공정이고, 생물학적 처리는 미생물을 이용하여 COD(Chemical Oxygen Demand), 질소 및 인을 제거하는 공정이며, 고도처리는 잔류하는 SS, COD, 질소 및 인을 방류수질 기준 이하로 처리하는 공정이다.Generally, the process for high concentration wastewater treatment consists of pretreatment, biological treatment, and advanced treatment. Pretreatment is the process of removing impurities and SS (Suspended Solid), biological treatment is the process of removing chemical oxygen demand (COD), nitrogen and phosphorus using microorganisms, and advanced treatment is the remaining SS, COD, nitrogen and phosphorus It is a process to treat below the discharge water quality standard.

이때, 고도처리에 적용되는 처리공정은, 응집침전, 펜톤산화, 오존산화, 모래여과, 활성탄흡착, UF(Ultra filtration) 및 RO(reverse osmosis) 막분리 공정 등의 처리 방법들을 상호 조합하여 구성된다. 일반적으로 적용되고 있는 고도처리 공정으로는, i) UF 막분리-응집침전-펜톤산화-활성탄흡착, ii) 응집침전-오존산화-모래여과, iii) 오존산화-펜톤산화-모래여과, iv) UF 막분리-RO 막분리, v) RO 막분리 등이 사용되고 있으며, 이들의 주기능은 COD 와 SS 를 제거하는 것이다.At this time, the treatment process applied to the advanced treatment is composed of a combination of treatment methods such as flocculation sedimentation, fenton oxidation, ozone oxidation, sand filtration, activated carbon adsorption, UF (Ultra filtration) and reverse osmosis (RO) membrane separation process . Commonly applied advanced treatment processes include i) UF membrane separation-flocculation-penton oxidation-activated carbon adsorption, ii) flocculation precipitation-ozone oxidation-sand filtration, iii) ozone oxidation-fenton oxidation-sand filtration, iv) UF membrane separation-RO membrane separation, v) RO membrane separation, etc., and their main function is to remove COD and SS.

이러한 종래의 고도처리 공정에 적용된 대부분의 처리방법에는 오존산화와 펜톤산화가 포함되어 있으나, 난분해성 COD 를 산화/분해하는 데에 요구되는 산화력이 과다하여 완벽하게 분해/산화할 수 없으며 동시에 색도유발물질이 잔류하는 문제가 발생되고 있다. 그리고, 난분해성 COD 의 일부가 생분해성 COD 로 전환되어 처리후의 BOD(Biological Oxygen Demand)가 상승하는 추가적인 문제가 발생되고 있다.Most of the treatment methods applied to the conventional high-treatment process include ozone oxidation and fenton oxidation, but due to the excessive oxidation power required to oxidize / decompose the hardly decomposable COD, it cannot be completely decomposed / oxidized. There is a problem of remaining material. In addition, a portion of the hardly decomposable COD is converted into biodegradable COD, thereby causing an additional problem of increasing the biochemical oxygen demand (BOD) after treatment.

또한, UF 및 RO 막분리 공정의 운영으로 인해, 막폐쇄 현상에 따른 투과수량(flux)의 감소와 회수율(recovery) 향상을 위한 물리/화학적 세정 실시의 필요성 등과 같은 유지관리상의 어려움이 있고, 막손상시 처리수질이 악화되는 문제점이 있다. 특히, UF 막분리 공정은 잔류 COD 와 색도유발물질을 제거하지 못한다는 단점이 있다.In addition, due to the operation of the UF and RO membrane separation process, there are difficulties in maintenance, such as the need for physical / chemical cleaning to reduce the flux and improve recovery due to the membrane closure phenomenon. When damaged, there is a problem that the treated water quality deteriorates. In particular, the UF membrane separation process has a disadvantage in that it does not remove residual COD and color causing substances.

그리고, 고농도 폐수의 생물학적 처리 후 아질산성 질소(NO2-N) 및 질산성 질소(NO3-N) 농도가 매우 높으나, 기존의 고도처리 방법으로는 이를 제거할 수 없으므로 방류수질 기준을 초과하는 현안 문제를 가지고 있다.In addition, nitrite nitrogen (NO 2 -N) and nitrate nitrogen (NO 3 -N) concentrations are very high after biological treatment of high concentration wastewater, but they cannot be removed by the existing high-treatment methods. I have a problem.

본 발명은 이상과 같은 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 생물학적 처리수에 잔류하는 난분해성 COD 와 색도유발물질, SS, 질소 및 인의 처리 방법을 순차적으로 단순하게 구성하여 효율적, 경제적으로 처리 및 제거할 수 있는 폐수 고도처리 방법을 제공하는 것이다.The present invention has been made to solve the above problems, the object of the present invention is to simply and efficiently configure the method of treatment of the hardly degradable COD and chromatic inducing substances, SS, nitrogen and phosphorus remaining in biologically treated water, It is to provide an advanced wastewater treatment method that can be economically treated and removed.

이와 같은 본 발명에 의하면, 생물학적 처리수에 잔류하는 난분해성 COD 와 색도유발물질, SS, 질소 및 인이 단순한 공정에 의해 효율적, 경제적으로 처리 및 제거된다.According to the present invention as described above, the hardly decomposable COD remaining in the biologically treated water, the color causing substances, SS, nitrogen, and phosphorus are efficiently and economically treated and removed by a simple process.

이하에서는 도면을 참조하여 본 발명을 보다 상세히 설명한다. 도 1 은 본 발명에 따른 고도처리 방법을 실시하기 위한 처리 계통을 도시한 도면이다.Hereinafter, with reference to the drawings will be described the present invention in more detail. 1 is a view showing a processing system for implementing a high processing method according to the present invention.

도면에 도시된 바와 같이, 본 발명에 따른 고도처리 방법은, 생물학적 처리공정에 의해 처리된 유출수에 대하여 수행되는 응집침전/부상 공정, 오존산화 공정, BAF(Biological aerated filtration) 공정, 및 활성탄 흡착 공정을 포함하여 구성된다.As shown in the figure, the advanced treatment method according to the present invention, a flocculation sedimentation / flotation process, ozone oxidation process, BAF (Biological aerated filtration) process, and activated carbon adsorption process performed on the effluent treated by biological treatment process It is configured to include.

응집침전/부상 공정에서는 생물학적 처리공정에서 처리된 유출수에 응집제(coagulant)를 주입하고, 응집에 의해 형성된 플럭(floc)을 침전 또는 부상방법을 통해 고액분리한다. 이에 의하여, 고농도 폐수의 생물학적 처리수(유출수)에 다량 존재하는 잔류 난분해성 COD 와 색도유발물질, SS 및 인이 제거된다.In the flocculation sedimentation / floating process, a coagulant is injected into the effluent treated in the biological treatment process, and flocs formed by flocculation are solid-liquid separated through a precipitation or flotation method. As a result, the residual hardly decomposable COD and chromatin-causing substances, SS and phosphorus, which are present in large amounts in the biologically treated water (effluent) of the high concentration wastewater, are removed.

오존산화 공정에서는 응집침전/부상 공정에 의해 처리된 처리수에 오존을 공급하여 잔류하는 난분해성 COD 및 색도유발물질이 생분해성 COD 로 전환되거나 또는 산화/제거된다.In the ozone oxidation process, ozone is supplied to the treated water treated by the flocculation sedimentation / floating process so that the remaining hardly decomposable COD and color-causing substances are converted into biodegradable COD or oxidized / removed.

종래 생물막 공정 중의 한 종류인 BAF(Biological Aerated Filter)는 담체에 미생물이 부착되어 생물막을 형성하도록 부상식 여재(담체)를 반응조에 충전하여 생물학적인 처리와 물리적인 여과과정을 동시에 수행하여 질산성질소 및 BOD, COD, SS 등의 오염물을 제거하게 되며 구조가 단순하고, 수질이 안정적이고, 다량의 미생물을 여재에 부착시킴으로써 짧은 체류시간에 최대의 처리 효율을 얻을 수 있다.BAF 공정에서는 오염 유기물에 대한 흡착과 미생물이 부착성장하기 적절한 부상식 여재를 반응조에 충전하여 오존산화 공정에 의하여 생분해성 COD 로 전환된 유기물이 미생물에 의해 제거되고, 잔류하는 아질산성 질소(NO2-N) 및 질산성 질소(NO3-N)가 탈질미생물을 이용하여 제거됨과 동시에 SS 가 여과작용에 의해 제거된다.The BAF (Biological Aerated Filter), a type of conventional biofilm process, is filled with a floating filter (carrier) in a reaction tank so that microorganisms are attached to a carrier to form a biofilm, thereby simultaneously performing biological treatment and physical filtration. And contaminants such as BOD, COD, SS, etc. are removed, and the structure is simple, the water quality is stable, and a large amount of microorganisms are attached to the media to obtain the maximum treatment efficiency in a short residence time. Adsorption to the microorganisms and the growth of the microorganisms, which are suitable for growth, were filled in a reaction tank, and organic matter converted to biodegradable COD by the ozone oxidation process was removed by the microorganisms, and residual nitrite nitrogen (NO 2 -N) and nitrates Nitrogen (NO 3 -N) is removed using denitrification microorganisms and SS is removed by filtration.

활성탄 흡착 공정에서는 BAF 공정에 의해 처리된 처리수에 잔류하는 COD 와 SS 가 제거된 후에 방류된다.In the activated carbon adsorption process, COD and SS remaining in the treated water treated by the BAF process are removed and then discharged.

이상과 같은 공정들로 이루어진 본 발명에 따른 고도처리 방법을 적용한 경우의 폐수 처리효율을, 종래의 고도처리 방법중 하나인 응집침전-오존산화-모래여과 방법과 비교하면 다음의 표와 같다. 다음의 표 1 은 종래의 응집침전-오존산화-모래여과 방법(A 방법)에 의한 처리효율과 처리수질을 도시한 표이고, 표 2 는 본 발명의 고도처리 방법(B 방법)에 의한 처리효율과 처리수질을 도시한 표이며, 표 3 은 A 방법과 B 방법에서의 고도처리 효율을 비교한 것이다.The wastewater treatment efficiency when the advanced treatment method according to the present invention comprising the above processes is applied is compared with the coagulation sedimentation-ozone oxidation-sand filtration method which is one of the conventional advanced treatment methods.
