전기분해공정을 이용한 정수장치{Water treatment system by electrolysis}Water treatment system using electrolysis process {Water treatment system by electrolysis}

본 발명은 고효율의 전기분해공정을 이용한 정수장치에 관한 것으로 보다 상세히는 광촉매를 함유한 담체와 분리막을 이용하는 고도산화공정을 이용하여 공동집수장치의 물을 정수하고(녹, 병원성 미생물, 휘발성 유기물, 및 발암물질 제거) 전극부에 초음파 장치가 설치된 전기분해장치를 설계하여 전기분해장치의 전극에 침적되는 스케일을 효율적으로 제거하여 전기분해 효율을 높여 각 전극부에서 산성수와 알칼리수를 생산하는 정수장치에 관한 것이다.The present invention relates to a water purification device using a high-efficiency electrolysis process, and more particularly, to purify the water in the co-collecting device using a high oxidation process using a carrier and a separator containing a photocatalyst (rust, pathogenic microorganisms, volatile organics, And carcinogen removal) Designed electrolysis device equipped with ultrasonic device in the electrode part to efficiently remove the scale deposited on the electrode of the electrolysis device to increase the electrolysis efficiency to produce acidic water and alkaline water in each electrode part It is about.

오수 및 음용수 정화에 있어서, 일반적으로 다양한 크기의 필터를 사용하거나 전기분해를 실시하여 유해물질을 제거하고 있다. 전기분해공정을 이용하여 물을 전기분해할 경우 산성수와 알칼리수를 생산하는 것이 가능하며, 산성수는 세안이나 식물의 공급수에 사용되고 알칼리수는 음용수로 사용되어 건강한 물을 공급할 수 있다. 그러나, 물을 전기분해할 경우 제거되지 않은 유해 유기물, 세균 및 녹 성분이 다량 존재할 경우 전기분해만으로는 제거가 불가능하고 이러한 유해유기물이나 세균 등은 건강에 치명적이므로 반드시 제거되어야 한다. 특히, 현재 상품화된 전기분해를 이용한 정수기는 기존의 노후된 정수관을 통한 물을 사용하기 때문에 안전성이 보장이 되지 않으므로 전처리로서 반드시 유해물질을 제거해야 한다. 또한 전기분해시 유해유기물질 및 무기물질에 의해서 전극이 오염되면 전기분해 효율이 떨어지게 된다.In purifying sewage and drinking water, generally, various sizes of filters or electrolysis are used to remove harmful substances. When water is electrolyzed using the electrolysis process, it is possible to produce acidic water and alkaline water, and acidic water is used for washing or plant feed water and alkaline water is used as drinking water to supply healthy water. However, if a large amount of harmful organics, bacteria, and rust components that are not removed when water is electrolyzed is not possible to be removed by electrolysis alone, and these harmful organic substances or bacteria are fatal to health and must be removed. In particular, water purifiers using commercialized electrolysis currently use water through the old aged water purification pipes, so safety is not guaranteed and must be removed as a pretreatment. In addition, when the electrode is contaminated by harmful organic and inorganic substances during electrolysis, the electrolysis efficiency is reduced.

대한민국 특허 제436982호는 활성탄을 이용하여 전화를 유도하고 전기산화공정을 행하는 정수처리장치에 관한 것이다. 또한 대한민국 실용신안 제221980호는 수돗물에 포함된 유해물질을 제거하기 위하여 다수의 정수필터를 거친 후 전기분해를 실시하고 세라믹 메탈과 자외선을 통과하여 기능수를 제조하는 장치에 관한 것이다.Korean Patent No. 436982 relates to a water treatment apparatus for inducing a telephone and performing an electrooxidation process using activated carbon. In addition, the Republic of Korea Utility Model No. 221980 relates to a device for producing a functional water by passing through a plurality of water filters to remove harmful substances contained in the tap water and electrolysis and through the ceramic metal and ultraviolet light.

상기 발명과 고안은 전기분해공정 전에 활성탄과 정수필터를 이용하여 유해물질을 제거하고 있으나, 제거된 유해물이 필터에 남아서 필터의 교환 주기에 영향을 미치게 된다. 또한, 전기분해장치의 전극에 스케일이 쌓이게 되어 전기분해 효율 또한 떨어지게 된다.The invention and the invention is to remove the harmful substances by using activated carbon and water purification filter before the electrolysis process, but the removed harmful substances remain in the filter affects the replacement cycle of the filter. In addition, the scale is accumulated on the electrode of the electrolysis device is also reduced electrolysis efficiency.

또한, 대한민국공개특허 제2001-0026409호 및 공개특허 제2004-15928호는 광촉매를 이용한 광산화시스템과 막분리를 결합하여 상수 및 난분해성 오, 폐수를 처리하는 공정에 대하여 기제하고 있다. 광촉매가 부유된 반응조에 전처리된 처리수를 유입하여 산화반응을 시킨 후 처리수에 혼합된 광촉매를 분리하기 위하여 막분리를 실시하고 하는 공정을 포함하는 수처리하는 공정으로서, 상기 발명들은 광촉매를 분리하기 위하여 막분리공정을 사용하였으나 광촉매의 입자가 미세하므로 회수의 어려움이 있으며 회수된 광촉매는 일정처리를 거쳐 재투입되는 데에도 처리공정을 요하고 있다. 또한 일정시간 후에 분리막 표면에 광촉매 케이크가 쌓이게 되므로 이를 제거하여 회수하고 다시 문리공정을 수행하여야 하므로 공정의 효율이 떨러지며, 경제적이지 못하다.In addition, Korean Patent Publication Nos. 2001-0026409 and 2004-15928 disclose a process for treating water and hardly decomposable wastewater by combining membrane separation with a photocatalyst and membrane separation. A process for water treatment comprising the step of performing membrane separation to separate the photocatalyst mixed in the treated water after the oxidation of the pretreated treated water into the reaction tank in which the photocatalyst is suspended. For this purpose, the membrane separation process is used. However, since the particles of the photocatalyst are fine, it is difficult to recover and the recovered photocatalyst is required to be re-introduced through a predetermined treatment. In addition, since the photocatalyst cake is accumulated on the surface of the separator after a predetermined time, the efficiency of the process is low and economical because it has to be removed and recovered.

따라서, 상기 문제점을 해결하기 위하여 본 발명은 광촉매가 함유된 담체 및 광촉매가 함유된 분리막을 통해 공급수를 전처리하여 전극의 오염을 최대한 줄일 수 있으며, 여과된 유기물 등이 분리막 표면에서 광촉매에 의하여 분해반응이 동시에 일어나므로 담체 및 분리막의 수명이 연장될 수 있도록 하여 전기분해 효율을 높인 공동정수장치를 제공하는 것을 목적으로 한다.Therefore, in order to solve the above problems, the present invention can pretreat the feed water through a carrier containing a photocatalyst and a separator containing a photocatalyst to reduce contamination of the electrode as much as possible, and the filtered organic material is decomposed by the photocatalyst on the surface of the separator. Since the reaction takes place at the same time, it is an object of the present invention to provide a co-purifying device with improved electrolysis efficiency by allowing the life of the carrier and the separator to be extended.

또한, 본 발명의 목적은 전기분해장치 중 전극부분에 초음파 장치를 설치하여 전극에 스케일이 쌓이는 것을 방지하는 정수장치를 제공하는 것이다.In addition, it is an object of the present invention to provide a water purifier to prevent the accumulation of scale on the electrode by installing an ultrasonic device in the electrode portion of the electrolysis device.

또한, 본 발명은 기능성과 안전성을 갖춘 양질의 물을 제공하는 데 그 목적이 있다.It is also an object of the present invention to provide high quality water with functionality and safety.

도 1은 본 발명의 정수장치의 공정도를 간단히 나타낸 것이다.Figure 1 shows a simplified process diagram of the water purifying apparatus of the present invention.

이에 본 발명자들은 상기와 같은 문제점을 해결하기 위하여 광촉매를 고정화시킨 담체와 광촉매를 함유한 분리막을 이용한 고도산화공정을 실시하고 전기분해 공정 내에 초음파 장치를 도입하여 정수장치를 제조하였습니다.In order to solve the above problems, the present inventors have carried out an advanced oxidation process using a carrier having a photocatalyst immobilized thereon and a separator containing a photocatalyst, and introduced an ultrasonic device in the electrolysis process to manufacture a water purification device.

이하, 도 1을 참조로 본 발명을 구체적으로 설명한다Hereinafter, the present invention will be described in detail with reference to FIG. 1.

본 발명은 정수장치에 있어서, 집수장치로부터 상부에서 유입되는 원수 또는 수돗물이 저장될 수 있도록 일정한 내부공간을 가지며 상기 내부공간에 자외선 램프(130)가 설치되고 광촉매를 함유한 담체(110)을 포함하고 광촉매가 함유된 중공사로 제조된 한외여과 또는 정밀여과 분리막(120)이 설치된 반응조(100)와; 여과장치를 통한 처리수를 산성수와 알칼리수로 제조하기 위하여 전극부에 초음파 장치가 설치된 전기분해 장치(200);를 포함하는 전기분해공정을 이용한 정수장치에 관한 것이다.In the water purifying apparatus, the water purifying apparatus includes a carrier 110 having a constant internal space for storing raw water or tap water introduced from the water collecting apparatus and having an ultraviolet lamp 130 installed therein and containing a photocatalyst. And a reactor 100 in which ultrafiltration or microfiltration membranes 120 made of hollow fiber containing a photocatalyst are installed; It relates to a water purification device using an electrolysis process, including; electrolysis device 200 equipped with an ultrasonic device in the electrode unit for producing the treated water through the filtration device to acidic and alkaline water.

상기 반응조는 광촉매 담체를 가득채워 고정층으로 사용하거나, 적정량만을 채워서 표면적이 증가된 유동층으로 사용할 수 있다. 광촉매를 담체에 함유시키지 않고 단독으로 사용하며 회수의 어려움으로 고가의 광촉매를 사용하는 데 다른 경제적인 문제점이 발생한다.The reactor may be used as a fixed bed by filling the photocatalyst carrier, or may be used as a fluidized bed having an increased surface area by filling only an appropriate amount. Another economical problem occurs when the photocatalyst is used alone without containing the photocatalyst and the expensive photocatalyst is used due to the difficulty of recovery.

상기 분리막은 광촉매 입자가 함침된 평막형태의 한외여과 또는 정밀여과 모듈로 제조하여 자외선 조사시에 광분해반응과 살균효과 있으므로 분리막 표면에 케이크가 쌓이는 것이 방지되어 분리효율이 향상되도록 하며, 종래기술과 같이 광촉매를 분리하기 위한 목적이 아니라, 정수를 목적으로 하고 있다.The separation membrane is manufactured by the ultrafiltration or microfiltration module in the form of a flat membrane impregnated with photocatalyst particles, so that photocatalytic reactions and bactericidal effects during ultraviolet irradiation are prevented from accumulating cake on the surface of the separator to improve separation efficiency, as in the prior art. The purpose is not to separate the photocatalyst, but to purify the water.

그리고 상기 자외선 램프는 광촉매의 광반응의 광원으로써 뿐만 아니라 자외선살균도 동시에 이루어지도록 하는 수단이다.The ultraviolet lamp is a means for simultaneously performing ultraviolet sterilization as well as a light source for photoreaction of the photocatalyst.

또한, 본 발명은 상기 담체(110)와 분리막(120)에 함유되는 광촉매가 TiO2을 주성분으로 하는 것을 특징으로 한다. 상기 TiO2이외에도 유기물 또는 세균분해 효과가 있는 금속산화물을 추가로 첨가할 수 있다.In addition, the present invention is characterized in that the photocatalyst contained in the carrier 110 and the separator 120 contains TiO 2 as a main component. In addition to the TiO 2 , an organic material or a metal oxide having a bactericidal effect may be further added.

뿐만 아니라, 본 발명은 상기 담체(110)로 중공사를 이용하는 것을 특징으로 한다. 상기 담체로 사용되는 중공사는 여과 장치에서 사용하는 중공사 분리막과 동일한 조성물을 이용하여 중공사를 제조하고 일정길이 또는 원하는 모양으로 성형 및 제조하여 사용할 수 있다.In addition, the present invention is characterized in that using the hollow fiber as the carrier (110). Hollow yarn used as the carrier can be used to manufacture the hollow fiber using the same composition as the hollow fiber membrane used in the filtration device, molded and manufactured in a predetermined length or desired shape.

고도산화공정은 유기물 분해효율 및 살균효율을 높이기 위해서 반응조 내 체류시간이 길어야 하므로 이로 인해 반응조의 부피가 증가되어야 하므로 정수장치의 부피가 커지는 문제가 발생된다. 그러므로 이러한 문제를 해결하기 위하여 반응조에 광촉매가 결합된 분리막을 결합시키게 되면 분리막 표면에서 광촉매에 의해서 유기물 분해반응이 동시에 일어나고 또한 세균이 분리막을 통과하지 못하므로 살균효과를 극대화할 수 있는 큰 장점이 있다.The advanced oxidation process requires a long residence time in the reaction tank in order to increase the decomposition efficiency and sterilization efficiency of the organic material, which causes the problem that the volume of the water purification device increases due to the increase in the volume of the reaction tank. Therefore, in order to solve this problem, when the membrane combined with the photocatalyst is combined with the reaction tank, the organic decomposition reaction occurs simultaneously by the photocatalyst on the surface of the membrane, and bacteria do not pass through the membrane, thereby maximizing the sterilization effect. .

고도산화공정은 유기물의 제거에 매우 유용한 방법으로서 자외선과 광촉매를 결합하여 유기물의 분해율을 극대화할 수 있다. 이 때 광촉매를 고정화시키지 않고 나노입자 상태로 고도산화공정을 적용하면 반응 후에 광촉매 회수의 어려움이 있게 된다. 본 발명은 간단하면서 경제적인 방법으로 상업화된 광촉매 담지 제품보다 부력과 기타 성능이 우수한 담체를 제조하여 적용하였다.The advanced oxidation process is a very useful method for removing organic matter, and it can maximize the decomposition rate of organic matter by combining UV and photocatalyst. At this time, if the advanced oxidation process is applied in the form of nanoparticles without immobilizing the photocatalyst, it becomes difficult to recover the photocatalyst after the reaction. The present invention has been applied to manufacture a carrier having superior buoyancy and other performance than commercially supported photocatalyst products in a simple and economical manner.

또한, 전기분해공정에 초음파 장치를 도입하여 전극의 오염을 사전에 예방함으로서 전기분해장치의 효율감소를 줄일 수 있다. 전기분해공정에 사용하는 기존의 전처리공정은 오염이 쉽게 일어나서 전처리장치를 자주 교체해야 하는 어려움이 있다. 주 오염원인 유기물질을 고도산화공정을 이용하여 원천적으로 분해시킴으로서 또한 전기분해공정에 초음파 장치를 도입하여 전극의 오염을 사전에 예방함으로서 전극의 오염에 의한 전기분해장치의 효율감소를 줄임으로서 효율을 증대시킬 수 있다.In addition, by introducing an ultrasonic device in the electrolysis process to prevent contamination of the electrode in advance can reduce the efficiency of the electrolysis device. The existing pretreatment process used in the electrolysis process has a difficulty in frequently replacing the pretreatment apparatus due to contamination easily. It is possible to reduce the efficiency of the electrolysis device due to the contamination of the electrode by decomposing the organic material, which is the main pollutant source by the advanced oxidation process, and by preventing the contamination of the electrode in advance by introducing an ultrasonic device in the electrolysis process. You can increase it.

이와 같이 광촉매 담체와 광촉매 결합형 분리막을 동시에 적용하는 고도산화공정을 이용함으로써 전기분해장치에 공급되는 수질이 양호하여 전기분해 전극의 오염을 최소화할 수 있으므로 전기분해의 효율을 극대화시킬 수 있고 전극의 수명을 최대한 연장시킴으로서 전극의 교체비용을 최소화할 수 있다.Thus, by using the advanced oxidation process that simultaneously applies the photocatalyst carrier and the photocatalyst-coupled separator, the water quality to the electrolysis device is good and the contamination of the electrolysis electrode can be minimized, thereby maximizing the efficiency of electrolysis. By extending the life as much as possible, the replacement cost of the electrode can be minimized.

이하 실시예를 통하여 본 발명을 상세히 설명하면 다음과 같은 바, 본 발명이 실시예에 한정되는 것은 아니다.Hereinafter, the present invention will be described in detail with reference to the following Examples, but the present invention is not limited to the Examples.

광촉매인 티타니아 나노입자가 함유된 담체와 분리막을 이용한 고효율 고도산화공정을 거친 수돗물과 거치지 않은 수돗물의 전기분해공정에서 시간에 따른 전기분해효율(pH, 알칼리 수)을 표 4에 나타내었다. 고도산화공정을 거친 수돗물은 고도산화공정을 거치지 않은 수돗물에 비해서 시간에 따라 전기분해효율이 크게 감소하지 않는 반면 고도산화공정을 거치지 않은 수돗물은 전기분해효율이 크게 감소하는 것을 알 수 있다.Table 4 shows the electrolysis efficiency (pH, alkaline water) with time in the electrolysis process of tap water and non-tap water, which has undergone high-efficiency highly oxidative processes using a carrier and a membrane containing titania nanoparticles, which are photocatalysts. Tap water that has undergone advanced oxidation does not significantly reduce electrolysis efficiency over time compared to tap water that has not undergone advanced oxidation, whereas tap water that has not undergone advanced oxidation has significantly reduced electrolysis efficiency.

이상의 실시예에서 확인하였듯이 티타니아 나노입자를 고정화시킨 담체를 사용하여 고도산화공정을 적용할 경우 담체를 사용하지 않은 경우보다 효율은 크게 떨어지지 않으면서 회수가 용이하므로 효율을 크게 향상시킬 수 있었다. 또한, 고도산화공정의 사용부지를 최소화하고 효율을 극대화하기 위하여 나노입자가 함침된 분리막을 결합시킴으로서 세균의 완벽한 제거와 유기물 분해능을 향상시킬 수 있었다.As confirmed in the above embodiment, when the advanced oxidation process was applied using the carrier on which the titania nanoparticles were immobilized, the efficiency was greatly improved since the recovery was easy without significantly decreasing the efficiency than the case where the carrier was not used. In addition, by combining the membrane impregnated with nanoparticles in order to minimize the use site of the advanced oxidation process and maximize the efficiency, it was possible to improve the complete removal of bacteria and decomposition of organic matter.

상기의 결과로 고도산화공정을 거친 수돗물은 그렇지 않은 수돗물에 비해서 전기분해공정에 적용할 경우 전극의 오염이 최소화되므로 전기분해효율이 극대화되며 전극의 교체주기를 최소화할 수 있으며, 전기분해장치 내에 초음파 장치를 설치하여 전극을 세척할 경우 그렇지 않은 경우보다 전극의 오염을 최소화할 수 있었다.As a result, tap water which has undergone highly oxidation process is minimized contamination of electrode when it is applied to electrolysis process compared to tap water which is not so, electrolysis efficiency can be maximized and electrode replacement cycle can be minimized. Cleaning the electrode by installing a device could minimize contamination of the electrode than otherwise.

이상과 같이 본 발명의 유해물질의 정화 및 전극의 오염을 최소화시켜 전기분해의 효율을 향상시킨 정수장치를 제공할 수 있다.As described above, it is possible to provide a water purifying apparatus which improves the efficiency of electrolysis by purifying harmful substances of the present invention and minimizing contamination of electrodes.

또한, 본 발명은 광촉매를 함유하는 담체와 분리막을 사용하므로써 분리되는 유해물질이 광분해되므로 분리막 및 담체의 효율을 향상시켜 매우 경제적인 정수장치를 제공할 수 있다.In addition, the present invention can provide a very economical water purification device by improving the efficiency of the separation membrane and the carrier since the harmful substances are separated by the photolysis using the carrier and the membrane containing the photocatalyst.

또한, 본 발명은 아파트, 빌딩 및 공동주택 등에 설치하여 기능성이 부여된 물을 제공할 수 있는 정수장치를 제공할 수 있다.In addition, the present invention can provide a water purification device that can be installed in an apartment, a building, and a multi-unit house to provide water to which functionality is provided.
