Description
본 발명은 전기분해장치를 포함하는 고도산화처리장치 및 이를 이용한 고도산화처리방법에 관한 것이다.The present invention relates to an advanced oxidation treatment apparatus including an electrolysis apparatus and an advanced oxidation treatment method using the same.
산화법(Oxidation Process)은 염소나 오존과 같은 산화력이 강한 물질을 투입하여 오염물질을 처리하는 방법으로 수처리 분야에서 상수나 폐수 처리에 많이 사용되어 왔다. 특히, 염소(Cl)를 사용한 상수 처리는 다른 산화제를 사용하는 것보다 경제적이고 살균력에서 매우 우수한 산화법이라고 할 수 있지만, 1974년에 염소를 사용한 상수 처리과정에서 트리할로메탄(Trihalomethanes, THMs)이라는 발암물질이 생성된다는 것을 발견한 이후에 염소의 사용을 지양하고 오존을 사용하게 되었다. 오존(Ozone, O₃)은 산화력이 염소에 비해 뛰어나고, THM에 대한 분해 능력이 있으며, 용존산소를 증가시키는 효과가 있는 장점을 가졌으나, 유기물과 선택적으로 반응하기 때문에 반응하지 못한 유기물이 잔존하고, 성상에 따라서는 오염물질을 이산화탄소로 완전히 분해시키지 못하고, 알데히드(Aldehyde)나 브로메이트(Bromate, BrO3)와 같은 부산물을 생성하는 단점이 있었다.Oxidation process is a method of treating pollutants by injecting substances with strong oxidizing power, such as chlorine or ozone, and has been widely used for water treatment or wastewater treatment in the water treatment field. In particular, water treatment using chlorine (Cl) is more economical than using other oxidizing agents and can be said to be a very excellent oxidation method in sterilization power, but in 1974, in the water treatment process using chlorine, trihalomethanes (THMs) were used. After discovering that carcinogens were produced, the use of chlorine was stopped and ozone was used. Ozone (O₃) has superior oxidizing power compared to chlorine, has the ability to decompose THM, and has the effect of increasing dissolved oxygen, but because it selectively reacts with organic substances, unreacted organic substances remain, Depending on the properties, contaminants cannot be completely decomposed into carbon dioxide, and there is a disadvantage in that by-products such as aldehydes (Aldehyde) or bromate (BrO3) are generated.
그래서, 염소나 오존처리와 같은 화학 산화법의 단점을 극복하고 대안으로 나온 기술이 AOP(Advanced Oxidation Process, 고도산화처리방법)공정이다. 이 공정은 인위적으로 OH 라디칼(OH radical)을 생성시켜 오염물질을 분해 및 제거하고, 세균의 살균 및 바이러스의 불활성화를 하는데, OH 라디칼은 산화력이 다른 산화제에 비해 월등히 뛰어나고 비선택적으로 반응하기 때문에 유기염소화합물과 같은 난분해성 물질도 매우 신속히 분해하는 장점이 있다.Therefore, the AOP (Advanced Oxidation Process) process is an alternative technology that overcomes the disadvantages of chemical oxidation methods such as chlorine or ozone treatment. This process artificially generates OH radicals to decompose and remove contaminants, sterilize bacteria and inactivate viruses. Since OH radicals have superior oxidizing power compared to other oxidizing agents, they react non-selectively. It has the advantage of decomposing very quickly even difficult-to-decompose substances such as organic chlorine compounds.
하지만 기존의 AOP 공정은 폐수의 종류에 따라 제한적으로 적용 가능한 점, 고농도에 적용이 불가한 점, 이온결합 물질과 공유결합 물질을 동시에 해리하지 못한다는 한계가 있었다.However, the existing AOP process has limitations in that it can be applied limitedly depending on the type of wastewater, cannot be applied to high concentrations, and cannot dissociate ionic and covalent substances at the same time.
상기한 문제를 해결하기 위해, 본 발명의 목적은 폐수의 종류와 농도에 관계없이 이온결합 물질과 공유결합 물질을 동시에 해리하는 것이 가능한 순환식 고도산화처리장치 및 이를 이용한 순환식 고도산화처리방법을 제공하는 것에 있다.In order to solve the above problems, an object of the present invention is to provide a circulating advanced oxidation treatment apparatus capable of simultaneously dissociating ionic and covalently bonded materials regardless of the type and concentration of wastewater, and a circulating advanced oxidation treatment method using the same. is to provide.

The wastewater tank 100 is a storage tank in which wastewater is collected, and wastewater generated in factories, etc. is introduced or the highly oxidized wastewater of the present invention is introduced again and recirculated.
상기 폐수조(100)는 초음파 처리장치(110)을 일 측에 구비할 수 있다. 초음파 처리장치는 폐수에 초음파 처리를 하여 수질을 균질화하고, 폐수 내 존재하는 슬러지가 폐수조 벽에 들러붙는 것을 방지하며 폐수 내 존재하는 전자에 에너지를 공급하여 오염물질의 분해 효율을 높인다.The wastewater tank 100 may include an ultrasonic treatment device 110 on one side. The ultrasonic treatment device treats wastewater with ultrasonic waves to homogenize the water quality, prevent sludge existing in the wastewater from adhering to the wall of the wastewater tank, and supply energy to electrons in the wastewater to increase the decomposition efficiency of pollutants.
상기 오존 산화반응장치(200)는 오염물질을 산화시키는 산화제인 OH 라디칼을 발생시키는 장치이다. 상기 오존 산화반응장치(200)의 일 측에는 미세기포와 오존을 함께 발생시키는 장치를 포함한다. 직경이 5 ~ 50㎛인 미세기포 오존을 공급하여 폐수의 유해물질을 제거 또는 친수성 물질로 전환시킨다. 직경이 5~ 50㎛인 미세기포 오존은 재래식 오존공정(Bubble 직경 100~200㎛)에 비해 비표면적이 크고, 상승속도가 늦기 때문에 고도산화처리단계의 효율을 증가시키고, 오존의 이용효율을 향상시켜 일반 AOP 공정에 비해 오존 투입량을 절감할 수 있다. 또한, 상기 미세기포는 기포 계면에 표면장력이 작용하게 된다. 이 표면장력은 표면이 작게 형성되도록 작용하기 때문에 구형의 계면을 가지는 기포의 표면장력은 내부를 압축하는 힘으로 작용하게 된다. 이는 Young-Laplace 식의 이론상 직경이 작으면 작을수록 높게 형성된다. 상기한 힘으로 상기 미세고포가 소멸될 때 고온, 고압의 초음파와 프리라디칼을 발생하게 되면서 폐수 내의 유기물질을 분해시키고 바이러스를 살균하는 효과를 얻을 수 있다.The ozone oxidation reaction device 200 is a device for generating OH radicals, which are oxidizing agents that oxidize pollutants. One side of the ozone oxidation reaction device 200 includes a device for generating microbubbles and ozone together. It removes harmful substances from wastewater or converts them into hydrophilic substances by supplying ozone with microbubbles with a diameter of 5 to 50㎛. Microbubble ozone with a diameter of 5 to 50 μm has a larger specific surface area and a slower rise rate compared to the conventional ozone process (Bubble diameter 100 to 200 μm). This can reduce the amount of ozone input compared to the general AOP process. In addition, the microbubbles are subjected to surface tension at the bubble interface. Since this surface tension acts to form a small surface, the surface tension of the bubble having a spherical interface acts as a force compressing the inside. In theory, the smaller the diameter of the Young-Laplace equation, the higher it is formed. When the microbubbles are eliminated by the above force, high-temperature and high-pressure ultrasonic waves and free radicals are generated, thereby decomposing organic substances in wastewater and sterilizing viruses.
상기 관로형 초음파처리장치(300)는 폐수가 지나가는 관로에 연결한 초음파 발생장치이다. 관로를 통과하는 폐수에 초음파 처리하여 전자를 가속하고, 다량의 라디칼을 생성하여 오염물질 분해의 효율을 높인다.The pipe-type ultrasonic processing device 300 is an ultrasonic wave generator connected to a pipe through which wastewater passes. The wastewater passing through the pipeline is treated with ultrasonic waves to accelerate electrons and generate a large amount of radicals to increase the efficiency of decomposition of pollutants.
상기 관로형 영구자석(400)은 폐수가 지나가는 관로에 연결한 영구자석이다. 관로를 통과하는 폐수에 자기장을 제공하여 초음파에 의해 가속된 전자를 여러 각도로 휘어지는 움직임을 만들어 라디칼 생성 효율을 높인다.The conduit type permanent magnet 400 is a permanent magnet connected to a conduit through which wastewater passes. By providing a magnetic field to the wastewater passing through the pipeline, the electrons accelerated by ultrasonic waves are bent at various angles to increase the efficiency of generating radicals.
상기 자외선 산화반응장치(500)는 폐수에 자외선을 가하여 산화제인 OH 라디칼을 생성하는 장치이다.The ultraviolet oxidation reaction device 500 is a device for generating OH radicals as an oxidizing agent by applying ultraviolet rays to wastewater.
상기 자외선 산화반응장치(500)는 이산화티탄(TiO2)을 포함할 수 있다. 이산화티탄은 광촉매로서, 이산화티탄 입자에 UV가 조사되면 전자가 에너지를 받아 높은 에너지 준위로 올라가면서 전자-정공쌍이 형성된다. 형성된 전자-정공쌍은 각각 전자와 정공으로 분리되어 표면에 확산되고, 확산된 정공과 전자는 각각 라디칼을 형성하여 오염물질을 분해한다.The ultraviolet oxidation reaction device 500 may include titanium dioxide (TiO 2 ). Titanium dioxide is a photocatalyst, and when UV is irradiated to titanium dioxide particles, electrons receive energy and rise to a high energy level, forming electron-hole pairs. The formed electron-hole pairs are separated into electrons and holes, respectively, and are diffused on the surface, and the diffused holes and electrons form radicals, respectively, to decompose contaminants.
상기 전기분해장치(600)는 내부에 일정간격으로 유지되어 연결된 다수의 전극판에 전원을 인가하여 유입되는 폐수중의 오염물질인 COD(Chemical Oxygen demand, COD), 질소 화합물, 인계 화합물 등을 전기분해에 의해 분해할 수 있도록 한 전기분해에 의한 폐수처리장치이다. 상세하게는 오염물질의 분해는 불용성 전극 표면에 흡착된 수산화 라디칼과 오염물질 사이의 전자 전달에 의해 분해되는 직접 양극산화와 전해반응에 의해 생성될 수 있는 차아염소산, 오존, 과산화수소 또는 산화된 금속 이온과 같은 강한 산화제에 의해서 분해되는 간접산화에 의해 일어날 수 있다. 상기 전기분해장치를 사용 시 이온결합 물질과 상대적으로 결합력이 강한 공유결합 물질까지 분해할 수 있는 효과가 있다.The electrolysis device 600 is maintained at a predetermined interval therein and applies power to a plurality of connected electrode plates to supply COD (Chemical Oxygen demand, COD), nitrogen compounds, phosphorus-based compounds, etc., which are pollutants in the inflowing wastewater. It is a wastewater treatment device by electrolysis that can be decomposed by decomposition. In detail, the decomposition of contaminants is hypochlorous acid, ozone, hydrogen peroxide, or oxidized metal ions that can be generated by direct anodization and electrolytic reaction, which is decomposed by electron transfer between the hydroxyl radical adsorbed on the surface of the insoluble electrode and the contaminant. It can be caused by indirect oxidation, which is decomposed by strong oxidizing agents such as When the electrolysis device is used, there is an effect of decomposing an ionic material and a covalent material having a relatively strong bonding force.
상기 전기분해장치(600)은 양극과 음극을 포함하고, 양극과 음극의 극성을 일정 주기로 상호변환시키는 제어부(610)를 포함할 수 있다. 제어부(610)에 의해 양극과 음극의 극성을 상호 변화시켜, 양극과 음극에서 전기분해 산물로 전극표면에 석출되는 물질들을 전극으로부터 떼어 낼 수 있다. 전압 변화를 주어 전극의 별도 세척과정을 거칠 필요가 없어 공정을 단순화 할 수 있고, 공정을 중단하지 않고 폐수를 순환시켜 고도산화처리를 할 수 있다.The electrolysis device 600 may include an anode and a cathode, and a control unit 610 for mutually converting the polarities of the anode and the cathode at a predetermined period. By mutually changing the polarities of the anode and the cathode by the control unit 610 , materials deposited on the electrode surface as an electrolysis product at the anode and the cathode may be removed from the electrode. By applying a voltage change, there is no need to go through a separate cleaning process for the electrode, so the process can be simplified, and advanced oxidation treatment can be performed by circulating wastewater without stopping the process.
