Description

전기분해와 여재를 이용한 오폐수처리장치{Sewage and wastewater treatment system using electrolysis and media}Wastewater treatment system using electrolysis and media

현재까지 전기분해를 이용한 오폐수처리장치는 처리효율 및 공사비의 문제로 인해 현장 적용실적이 그다지 많지 않은 실정으로 이는 처리효율의 미흡과 부대장치비용이 고가인 때문에 기인하며, 특히 최소의 단위면적을 갖는 다수의 전극판을 사용하여 최대의 처리 표면적으로 처리효율을 극대화시키는 문제점을 해결해야 하는 문제점을 안고있다.To date, the wastewater treatment system using electrolysis has not much field application performance due to problems of treatment efficiency and construction cost, which is due to the lack of treatment efficiency and the high cost of auxiliary equipment, especially having a minimum unit area. There is a problem to solve the problem of maximizing the treatment efficiency by using a large number of electrode plates to the maximum treatment surface area.

근래에 들어 생활수준의 향상과 산업발달로 인해 하루에도 상당량의 오수 및 폐수가 배출됨에 따라 정부에서도 수질오염의 방지와 보다 맑은 물을 공급하기 위하여 그 배출되는 오수 및 폐수의 배출기준을 강화하여 기존 설비의 보완 또는 대치가 요구되었고, 그로 인한 신기술 개발이 시급한 실정에 이르렀다.Recently, due to the improvement of living standards and industrial development, a considerable amount of sewage and wastewater is discharged every day, so the government has strengthened the discharge standard of the discharged sewage and wastewater to prevent water pollution and to supply clearer water. Improvement or replacement of equipment was required, and new technology development was urgently needed.

또한 생활수준의 향상은 용수사용량이 급증을 초래하였고 이에따라 용수부족 현상이 발생되었다. 따라서 부족분의 용수를 해결하기 위하여 오.폐수를 처리하여 화장실 등의 중수도용으로 사용할 수 있도록 시도되고 있는 바, 종래 생물학적 처리공법은 반응속도가 느릴 뿐만 아니라 처리효율이 떨어져 중수도용으로 사용하기 곤란한 문제점이 있어 별도의 고도처리시설을 구비해야 하는 문제점이 있었다.In addition, the improvement of living standards resulted in a sharp increase in the amount of water used, resulting in water shortages. Therefore, in order to solve the shortage of water, it has been attempted to be used for heavy water treatment such as toilets by treating wastewater, and the conventional biological treatment method is difficult to use for heavy water due to low reaction rate and low treatment efficiency. There was a problem to be equipped with a separate advanced processing facility.

따라서, 최근에는 상기 생물학적 처리공법 보다 처리효율 및 처리속도가 뛰어나 부족한 생활용수 및 공업용수로도 사용가능한 물리·화학적 처리방법 위주로 중점적으로 연구되고 있는 실정이며, 그 중에서도 전기분해를 이용한 오폐수처리방법이 부각되고 있는 실정이다.Therefore, in recent years, the research has focused on the physical and chemical treatment methods that can be used as living water and industrial water, which have a higher treatment efficiency and treatment speed than the biological treatment methods, and among them, wastewater treatment methods using electrolysis are highlighted. It's happening.

통상의 전기적 원리를 이용한 오수처리방법을 개략적으로 설명하면 먼저, 보다 큰 효율을 가질 수 있도록 처리하고자 하는 처리수를 전처리 공정인 조정조에 투입시킨 후 가성소다, 무기응집제 및 적절한 첨가제(NaCl, Na2so4)등을 넣고 혼합하여 전도성을 조정하는 단계를 거치게 한다.Sewage treatment method using a conventional electrical principle is outlined first, the treated water to be treated in order to have a greater efficiency, and then added to the control tank, a pretreatment process, caustic soda, inorganic coagulant and appropriate additives (NaCl, Na2so4) Mix the back and mix to adjust the conductivity.

반응기 내부로 유입된 오폐수는 전극판 사이를 통과하면서 전기응집반응을 일으키며, 이러한 전기응집반응은 주로 다음의 반응에 의해서 일어나며 그것은 응집(coagulation), 부상(flotation), 산화(oxidation)등 이다.Wastewater introduced into the reactor passes through the electrode plates, causing an electroaggregation reaction, which is mainly caused by the following reactions: coagulation, flotation and oxidation.

이중 산화(oxidation)와 응집(coagulation)은 폐수처리 이론중 가장 핵심적 반응이며 산화(oxidation) 과정은 전극판의 (+)극중의 금속형태의 철이 +2 또는 +3가의 이온상태로 산화되며, 음극에서 발생된 수산화 이온(OH-)이 산화되면서 산소(O2)가 발생된다. 이렇게 발생된 산소(O2)는 유기물의 간접적인 산화(indirectoxidation)에 관여하며 이와 동시에 전극판의 음극에서는 환원이 일어나 중성조건에서 수산화 이온(OH-), 산성조건에서 수소(H2) 가스가 발생된다.Double oxidation and coagulation are the most important reactions in the theory of wastewater treatment. The oxidation process involves the oxidation of the metal in the positive electrode of the electrode plate to +2 or + trivalent ions. Oxygen (O2) is generated as the hydroxide ions (OH-) generated from the oxidized. Oxygen (O2) generated in this way is involved in indirect oxidation of organic materials, and at the same time, reduction occurs at the cathode of the electrode plate to generate hydroxide ions (OH-) under neutral conditions and hydrogen (H2) gas under acidic conditions. .

한편, (+)극에서 용출된 금속이온은 수중의 pH 조건에 따라 산성 또는 중성의 조건에서 (+)전하를 띤 금속수화물 복합체를 형성하며, 강알칼리성 조건에서 (-)전하를 띤 금속수화물 복합체를 형성하게 된다. 따라서 일반적으로 유입 오폐수의 pH가 중성 또는 약산성 조건에서 운전이 되므로 (+)전하를 띤 금속수화물 복합체와 (-)전하를 띤 유기오염물질인 콜로이드(Colloid)의 표면전하를 전기적으로 중화시켜 이중층압축(Double layer compression)에 의한 응집을 통해 유기물이 응집 침전된다.On the other hand, the metal ions eluted at the (+) electrode form a metal hydrate complex with a (+) charge under acidic or neutral conditions, depending on the pH conditions in the water, and a metal hydrate complex with a (-) charge under strongly alkaline conditions. Will form. Therefore, in general, the pH of the influent wastewater is operated under neutral or weakly acidic conditions. Therefore, the double layer compression is performed by electrically neutralizing the surface charges of the metal hydrate complex with (+) charge and the colloid (Colloid) with (-) charge. Organic matter coagulates and precipitates through coagulation by double layer compression.

처리과정에서 생성된 응집침전물은 처리조 하부에 위치한 일정정도의 구배를 가지 슬러지침전부로 침강되며, 이를 주기적으로 슬러지배출관을 통해 펌프로 이송시킨다.The flocculation sediment produced during the treatment is settled to the sludge settling section having a certain degree of gradient located in the lower part of the treatment tank, and is periodically transferred to the pump through the sludge discharge pipe.

한편, 전극판의 산화·환원과정 중에 발생되는 기포(gas bubble)에 의해 응집된 물질이 부착되어 부유성 스컴(scum)이 발생되며, 부유성 스컴은 처리조에서 처리된 오폐수와 함께 처리조 다음에 위치한 부상분리조로 유입되며 이는 상부에 떠오른 부유성 스컴이 웨어를 넘어 스컴유출부으로 이동, 스컴배출관을 통해 부상분리조로 이동되며 처리수는 상부에 위치한 처리수배출관을 통해 처리된다On the other hand, the flocculated material is attached by the bubbles generated during the oxidation / reduction process of the electrode plate, and the floating scum is generated, and the floating scum is treated with the waste water treated in the treatment tank. The floating scum that floated on the upper part is moved to the scum outlet through the scum discharge pipe and the scum discharge pipe is moved to the flotation tank through the scum discharge pipe, and the treated water is treated through the treatment water discharge pipe located on the upper part.

그러나, 상기한 종래의 오수처리장치에 있어서는 전기분해부의 처리효율은 원통형상으로 겹쳐지게 형성된 각 전극관의 폭과 길이에 비례함에 따라 겹쳐지는 각 전극판을 넓은 폭을 갖도록 형성시킴은 물론 길이를 길게 함으로써, 처리효율을 향상시킬 수 있었으나, 그로 인한 오수처리장치의 전체적인 크기가 커지게 되어(scale up) 설치상에 많은 문제점이 발생됨은 물론 설치비용이 증가되는 문제점이 초래되었다.However, in the conventional sewage treatment apparatus, the treatment efficiency of the electrolysis part is formed to have a wide width as well as the length of each overlapping electrode plate in proportion to the width and length of each electrode tube formed to overlap in a cylindrical shape. By lengthening, the treatment efficiency could be improved, but the overall size of the sewage treatment apparatus was increased, resulting in many problems in installation as well as an increase in installation cost.

또한, 전기적인 반응에 의해 상기 각 전극판은 일정사용기간이 지나게 되면 교체하여야 하는 데, 상호 겹쳐져 있는 각 전극판을 처리조에서 이탈시키고 삽입시켜야 하는 교체과정이 상당히 불편할 뿐만 아니라 그에 따른 많은 추가 비용이 소요되는 문제점이 발생하였다.In addition, due to the electrical reaction, each of the electrode plates must be replaced after a certain period of use, and the replacement process of removing and inserting each overlapping electrode plate from the treatment tank is not only inconvenient, but also enormously expensive. This required problem occurred.

이에, 본 고안은 상기와 같은 종래의 제반 문제점을 해소하고자 안출한 것으로, 그 목적은 전기분해를 이용한 오폐수처리장치에 최소의 단위면적을 갖는 다수의 전극판을 사용하여 최대의 처리 표면적으로 처리효율을 극대화 시키고, 전극판의 교체 또한 용이하도록 하여야 한다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the object of which is to maximize the treatment surface area by using a plurality of electrode plates having a minimum unit area in the wastewater treatment apparatus using electrolysis Should be maximized and replacement of electrode plate should be easy.

따라서 상기와 같은 문제점을 해결하기 위하여 처리조는 오폐수의 처리속도가 빠르고, 부하변동에 따른 조건의 조정이 용이하며, 적절한 첨가제(NaCl, Na2SO4) 에 의해 오폐수내의 질소성분까지 동시에 제거할 수 있는 오폐수고도처리시스템과, 유체역학적인 해석을 의해 도출된 유입수 최적분배장치 및 입자상 물질의 침강특성 최적화 반응기 용량 및 구조를 적용하여 주반응기내에서 침전 효과까지 이루어 침전시스템을 축소킴으로써 소요부지 및 설치비를 절감하며, 소요 약품량을 제어함으로써 유지비를 최소화하는 고품위의 경제적인 장치이어야 한다.Therefore, in order to solve the above problems, the treatment tank has a high speed of treatment of wastewater, easy adjustment of conditions according to load fluctuations, and wastewater altitude that can simultaneously remove nitrogen components in wastewater by appropriate additives (NaCl, Na2SO4). Reduction of sedimentation system and installation cost by reducing the sedimentation system through the sedimentation effect in the main reactor by applying the treatment system, the effluent distribution system and the sedimentation characteristics optimization of particulate matter derived from hydrodynamic analysis It should be a high quality economical device that minimizes maintenance costs by controlling the amount of chemicals required.

또한 전기분해를 이용한 오수처리장치는 무기응집제의 투여와 전극판에 의한 산화·환원작용이 수행되어 빠른 시간내에 오폐수의 오염물질들이 분해되고, 침전성 입자상 물질이 유동을 층유화시켜 균일하게 분배시키는 처리조 내부에서 침전·배출되어 후단의 부상분리조에서 침전부하를 감소시킬 수 있는 기술을 요구하고 있다.In addition, the sewage treatment apparatus using electrolysis performs inorganic coagulant administration and oxidation / reduction by electrode plates to decompose contaminants in wastewater within a short time, and precipitated particulate matter uniformly distributes the flow by layer emulsification. There is a demand for a technology that can reduce the settling load in the flotation tank in the rear stage by being settled and discharged inside the treatment tank.

상기의 목적을 달성하기 위해 통상의 전기분해장치와 같이, 본 장치도 오폐수내의 입자상물질을 처리조 전단계에서 제거하기 위한 조치로 유입 오폐수를 오폐수처리장치(1) 전단계에 설치된 조정조에 일시 저장하여 침전시킨후, 가성소다, 무기응집제, pH 조정용재를 내산성이 저장탱크으로 부터 약품 정량주입펌프를 통하여 유입수 조정조 내부로 공급한다.In order to achieve the above object, like the conventional electrolysis device, this device also measures to remove particulate matter in the waste water at the previous stage of the treatment tank, and temporarily stores the influent waste water in the adjustment tank installed at the stage of the wastewater treatment apparatus 1 to settle it. After the caustic soda, inorganic coagulant, and pH adjusting material, acid resistance is supplied from the storage tank into the inflow water adjusting tank through the chemical injection pump.

조정조에는 적은용량의 교반기를 설치하여 공급된 약품과 유입오폐수가 완전 혼합하도록 하는 것이 중요하며, pH meter 와 Conductivity meter를 통하여 혼합된 오폐수의 pH 와 Conductivity를 제어판에서 인식하여 일정량에 달했을 때 펌프 및 교반기의 작동을 중지시킨다.It is important to install a small amount of stirrer in the adjusting tank so that the supplied chemical and influent waste water are completely mixed.When the pH and conductivity of the mixed waste water are recognized by the control panel, the pump and stirrer are reached. Stop the operation.

이렇게 약품과 혼합된 오폐수는 반응기 유입펌프(도면에는 생략되어 있슴)를 통하여 본 고안의 주처리장치인 오폐수처리장치(1)의 하부에 설치된 원수유입관(7)을 통해 오폐수처리장치(1)내로 유입되게 된다.The waste water mixed with chemicals is a wastewater treatment device (1) through a raw water inlet pipe (7) installed at the bottom of the wastewater treatment device (1), which is the main treatment device of the present invention, through a reactor inflow pump (not shown in the drawing). It will flow into.

상기의 처리수 분배장치에 의해 오폐수처리장치(1)로 유입된 오폐수는 도 1에 도시된바와 같이 균일간격으로 오폐수처리장치(1) 내에 엇갈리게 설치된 스테인레스 재질의 전극판(10) 사이를 통하여 오폐수처리장치(1) 상류로 이동하는 과정에서 전극판(10)의 (+) (-)극이 물속의 양이온, 음이온과 결합하여 슬러지응집이 발생하게 되며, 이들 발생슬러지는 슬러지수집부(11)에 포집되어 슬러지배출관(12)을 통해 제거된다.The wastewater introduced into the wastewater treatment device 1 by the treatment water distribution device is disposed between the electrode plates 10 made of stainless material staggered in the wastewater treatment device 1 at uniform intervals as shown in FIG. 1. In the process of moving upstream of the treatment apparatus 1, the (+) (-) electrode of the electrode plate 10 is combined with cations and anions in water to generate sludge agglomeration, and these sludges are collected in the sludge collecting part 11. Is collected in the sludge discharge pipe 12 is removed.

원활한 전기분해작용을 일으키기 위해 주기적으로 정류기에서 (+) (-)를 번갈아 공급해주는 방식보다는 전극판(10)을 (+)극과 (-)극을 구분 하여 설치한 후 항상 일정하게 전류를 공급해주는 것이 처리효율 향상을 위해 바람직하다.Rather than supplying alternating positive (+) and negative (-) in the rectifier periodically for the purpose of smooth electrolysis, the electrode plate 10 is installed separately from the (+) and (-) poles. It is desirable to improve the treatment efficiency.

전극판(10)은 오폐수처리장치(1) 내쪽면에 상호 엇갈리도록 설치되며, 전극판(10)의 고정은 리벳 등으로 고정시킨 후 실리콘 등으로 마감처리 한다.The electrode plate 10 is installed to cross each other on the inner surface of the wastewater treatment apparatus 1, and the electrode plate 10 is fixed with rivets and then finished with silicon.

이하, 본 고안의 바람직한 실시예를 첨부된 도면에 의해 좀더 상세하게 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in more detail as follows.

도 1은 본 고안의 구성을 나타낸 절개 사시도이며, 도 2는 본 고안에 따른 수류의 흐름을 나타낸 평면도를 도시하고 있다.1 is a cutaway perspective view showing the configuration of the present invention, Figure 2 is a plan view showing the flow of water flow according to the present invention.

상기한 본 고안의 오폐수처리장치(1)는 하부 일측에 처리수를 조정과정을 거친 처리수를 유입 시키기 위한 원수유입관(7)이 형성되며, 상부 일측면에는 전기분해와 여재층(8)을 통과한 처리수가 외부로 배출될 수 있도록 처리수 배출관(6)이 형성되며, 하부에는 상기 전기분해에 의해 발생된 응집물을 처리하기 위한 슬러지배출관(12)이 구비된다.The wastewater treatment apparatus 1 of the present invention has a raw water inlet pipe 7 for introducing the treated water after adjusting the treated water to one side of the lower side, and an electrolysis and media layer 8 on one side of the upper side. A treated water discharge pipe 6 is formed to discharge the treated water that has passed through to the outside, and a sludge discharge pipe 12 for treating the aggregates generated by the electrolysis is provided at a lower portion thereof.

오폐수처리장치(1)의 외측면에는 도면에 도시되어 있지는 않으나 통상적인 방법에 의해서 전극판(10)에 전류를 공급할 수 있게끔 전류공급단자를 설치하여 전극판(10)에 전기를 공급하게 된다.Although not shown in the figure on the outer surface of the wastewater treatment apparatus 1, a current supply terminal is provided to supply current to the electrode plate 10 by a conventional method to supply electricity to the electrode plate 10.

또한, 상기 오폐수처리장치(1)의 하부에 형성된 슬러지수집부(11)에 슬러지가 원활히 포집될 수 있게끔 오폐수처리장치(1)의 하부 형태를 좁게 형성하여 설치하는 것이 바람직하며, 오폐수처리장치(1)의 하부 경사각도에 따라 슬러지의 포집이 달라지게 된다.In addition, the sludge collection unit 11 formed at the lower portion of the wastewater treatment device 1 is preferably formed by narrowly forming the lower shape of the wastewater treatment device 1 so that sludge can be collected smoothly, and the wastewater treatment device ( The sludge collection will vary according to the lower inclination angle of 1).

이를 좀더 자세히 상술하면, 도 1에 도시된바와 같이 조정조에서 전처리단계를 거친 처리수는 상기 오폐수처리장치(1)의 하부에 형성된 원수유입관(7)을 통하여 오폐수처리장치(1)에 유입되어 지고, 오폐수처리장치(1)에 유입되어진 처리수는 처리조내에 엇갈려서 설치되어진 전극판(10)을 지나면서 상기에서 언급한 전기분해 작용을 일으키게 되며, 여재층(8) 지나면서 미처리된 불순물 등이 재차 제거되게 된다.In more detail, as shown in FIG. 1, the treated water that has undergone the pretreatment step in the adjustment tank is introduced into the wastewater treatment apparatus 1 through the raw water inlet pipe 7 formed at the lower portion of the wastewater treatment apparatus 1. The treated water introduced into the wastewater treatment device 1 passes through the electrode plate 10 installed alternately in the treatment tank to cause the above-mentioned electrolysis, and passes through the filter layer 8 and the untreated impurities. This will be removed again.

처리수는 도 2에 도시된바와 같이 상호 엇갈리게 설치되어 있는 전극판(10)을 통과하면서, 즉 상기 상호 엇갈리게 설치된 전극판(10)이 설치됨에 따라 형성된 경사진 유로를 따라 상측으로 통과되면서 전극판(10)의 전기작용에 의해 처리수에 함유되어 있는 불순물을 제거하는 것이다.As shown in FIG. 2, the treated water passes through the electrode plates 10 alternately installed as shown in FIG. 2, that is, the electrode plates are passed upward along the inclined flow paths formed as the mutually alternate electrode plates 10 are installed. The impurity contained in the treated water is removed by the electrical action of (10).

상기와 같이 전극판(10)을 통과한 처리수는 오폐수처리장치(1)의 상부에 설치된 처리수 배출관(6)을 거쳐 외부로 배출되어지고, 처리수에 함유되어 있던 응집물은 오폐수처리장치(1)의 하부에 형성된 슬러지수집부(11)에 포집된 후 슬러지배출관(12)을 통하여 배출되어 진다.As described above, the treated water passing through the electrode plate 10 is discharged to the outside through the treated water discharge pipe 6 installed at the upper portion of the wastewater treatment device 1, and the aggregate contained in the treated water is discharged to the wastewater treatment device ( After being collected in the sludge collecting unit 11 formed in the lower part of 1) is discharged through the sludge discharge pipe (12).

한편, 상기와 같이 전기반응을 이용함에 따라 전극판(10)을 일정사용기간이 소요되면 교체를 해야되는 데, 상기한 전극판(10)은 오폐수처리장치(1)에 형성된 리벳 등으로 끼워져 삽입된 상태에서 실리콘 등으로 마감재로 고정되어 있는 관계로, 마감재인 실리콘 등을 제거하게 되면 손쉽게 교체할 수 있는 조건을 갖는 것이다.On the other hand, according to the use of the electrical reaction as described above, the electrode plate 10 needs to be replaced when a certain period of use takes place, the electrode plate 10 is inserted into the rivets formed in the wastewater treatment apparatus 1 and inserted. Since it is fixed with a finish in a state such as silicon, if you remove the finish, such as silicon has a condition that can be easily replaced.

상술한 바와 같이 본 고안은 전기분해와 여재층을 이용한 오폐수처리장치에서 최소의 단위면적을 갖는 다수의 전극판을 사용하여 최대의 처리 표면적이 형성됨에 따라 시설의 최소화는 물론 처리효율을 극대화시킬 수 있는 효과를 갖는 것이다.As described above, the present invention can maximize the treatment efficiency as well as the minimization of facilities as the maximum treatment surface area is formed by using a plurality of electrode plates having a minimum unit area in the wastewater treatment apparatus using electrolysis and media layers. It is to have an effect.

또한 본 고안은 기존의 물리·화학적처리 및 생물학적처리보다 처리효율이 향상되고, 체류시간이 짧아 반응속도가 매우 빠르며, 전극판의 부식은 그다지 나타나지 않아 5년 이상 유지 될 것으로 판단되며, 따라서 극판의 교체비용이 적게 소모되어 처리시설 유지관리비용이 적게 소요될 것으로 판단된다.In addition, the present invention improves the treatment efficiency compared to the conventional physical and chemical treatments and biological treatments, and the reaction time is very fast due to the short residence time, and the corrosion of the electrode plate does not appear so that it will be maintained for more than 5 years. As the replacement cost is reduced, the maintenance cost of the treatment facility will be reduced.

아울러 본 고안에 따른 전기분해장치는 무기응집제의 투여와 3차원적 전극효과에 의해 산화·환원작용이 배가되어 단시간내에 오폐수의 오염물질들이 분해되고, 침전성 입자상 물질이 유동을 층유화시켜 균일하게 분배시키는 반응기 내부에서 침전·배출되어 후단의 부상분리조에서 침전부하를 감소시킬 수 있는 고도처리장치를 제공할 수 있다.In addition, the electrolysis device according to the present invention doubles the oxidation / reduction effect due to the administration of the inorganic coagulant and the three-dimensional electrode effect, so that the pollutants of the waste water are decomposed within a short time, and the precipitated particulate matter layer-flows to uniformize the flow.
