Description

수처리 방법 및 장치{The Wastewater Treatment Method and its System}The Wastewater Treatment Method and its System
본 발명은 하수, 오수 및 폐수를 비롯한 각종 폐수의 수처리 방법 및 장치에 관한 것으로, 보다 상세하게는 물리적, 화학적, 생물학적 처리시스템을 최대한으로 구현하여 전기분해법과 생물막법을 결합하여 수중에 존재하는 주요 오염인자인 유기성 물질과 입자상 물질, 영양염류 등의 제거를 통하여 처리수를 재이용 가능한 등급으로 정화하는 고도의 수처리 방법 및 장치에 관한 것이다.The present invention relates to a method and apparatus for water treatment of various wastewater, including sewage, sewage, and wastewater, and more particularly, to realize the physical, chemical, and biological treatment systems to the maximum, and to combine electrolysis and biofilm to exist in water. The present invention relates to a high water treatment method and apparatus for purifying treated water to a reusable grade by removing organic substances, particulate matter, nutrients, and the like, which are pollutants.
종래로 부터 오염수의 처리는 오염원에 따라 물리적 처리, 화학적 처리, 생물학적 처리 등 다양한 방법이 이용되고 있으나 개별단위공정에 의한 수처리는 환경의 통합적 관리라는 측면에서 아직 미흡한 점이 많으므로 환경복원기술과 통합환경관리 문제가 새로운 관심의 대상이 되고 있는 실정이다.Conventionally, various methods such as physical treatment, chemical treatment, and biological treatment are used for the treatment of polluted water, but water treatment by individual unit process is still insufficient in terms of integrated management of the environment, so it is integrated with environmental restoration technology. The issue of environmental management has been the subject of new interest.
상기 개별단위공정중 전기화학분해법이 공지되어 있으며, 일반적인 전기화학분해법은 무기성 또는 유기성 전해물질을 함유하는 폐수에 전기에너지를 주어 폐수속에 함유되어 있는 BOD, COD 성분을 전기화학적으로 처리하는 방법이다.The electrochemical decomposition method of the individual unit process is known, and the general electrochemical decomposition method is a method of electrochemically treating the BOD, COD components contained in the waste water by giving electrical energy to the wastewater containing inorganic or organic electrolytic material. .
즉, 폐수속에 함유되어 있는 콜로이드상의 물질의 대부부은 마이너스로 하전되어 있기 때문에 부유상태에 있으며, 이 상태에서 전기에너지를 주어 전기적으로 중화하여 응집 반응을 일으키는 동시에 산화, 환원반응도 일으키게 되는데, 이러한 전기적 중화는 일반적으로 가용성의 양극을 이용하여 이 양극 금속의 가수분해에 의한 금속 수산화물의 생성에 의해 볼 수 있으며, 양극으로서 이용되는 금속은 주로 알루미늄, 철 등이다.That is, most of the colloidal substances contained in the wastewater are in a suspended state because they are negatively charged, and in this state, they are electrically neutralized by giving electric energy to cause agglomeration reactions and also cause oxidation and reduction reactions. In general, soluble anodes can be used to produce metal hydroxides by hydrolysis of the anode metals, and the metals used as the anodes are mainly aluminum and iron.
상기 전기분해 반응은 고속 산화와 환원이 연속적으로 이루어져 산화, 환원, 분해, 석출, 중화, 응집 및 살균 등의 작용을 하며, 전극과 폐수의 경계면에서 전극반응과 전극반응 생성물의 폐수 중 성분과 작용하여 2차 반응이 일어나는 동시에 전극반응 생성물은 침전, 흡착 및 부상 등의 작용을 함으로써 물과 불순물을 분리하여 폐수를 처리하는 방법이다.The electrolysis reaction is performed by rapid oxidation and reduction in a continuous manner to perform oxidation, reduction, decomposition, precipitation, neutralization, aggregation, and sterilization, and the reaction between the electrode reaction and the components of the wastewater of the electrode reaction product at the interface between the electrode and the wastewater. The secondary reaction occurs at the same time the electrode reaction product is a method of treating wastewater by separating water and impurities by the action of precipitation, adsorption and flotation.
그러나 일반적인 전기분해법은 전극(+), (-)극이 고정화시켜 일정한 반응시간이후 스케일이 끼어 반응속도가 갈수록 지연되어 처리속도가 갈수록 낮아지는 경향이 있고, (+)에 Al 전극을 사용할 경우 Al 전극에서 Al이 석출되어 자주 교체를 해야 하는 경향이 있다.However, in general electrolysis, electrode (+) and (-) electrodes are immobilized and scale is stuck after a certain reaction time. Al precipitates out of the electrode and tends to be replaced frequently.
또한 공지된 생물막법은 담체를 이용하여 물리적 여과와 생물학적 처리를 병행하는 방법으로서, 상기 생물막법의 일반적인 방법은 담체충전층을 유체가 흘러갈 때 유체 속의 입자가 받는 유체역학적 작용, 입도에 따른 확산모델, 관성충돌, 입자와 담체간의 충돌 및 간섭에 의한 차단작용 등에 의한 물리화학적 여과기구와 담체표면에 부착하는 생물막에 의한 유기성 물질을 정화하는 것이다.In addition, a known biofilm method is a method of performing physical filtration and a biological treatment in parallel using a carrier, and the general method of the biofilm method is a hydrodynamic action and particle size diffusion which a particle in a fluid receives when a fluid flows through a carrier filled layer. Purification of organic substances by physicochemical filtration mechanisms and biofilms attached to the surface of the carriers, such as models, inertia collisions, collisions between particles and the carriers, and blocking effects caused by interference.
그러나 상기한 종래의 수처리방법에서는 수처리에 요하는 반응시간이 길고, 부지요구량이 많으며, 악취나 소음의 문제가 부수적으로 발생할 뿐만 아니라 소규모에서 대규모에까지, 또 저농도에서 고농도에 이르기까지 광범위하게 적용하기가 난해하다는 문제점이 있었다.However, in the conventional water treatment method described above, the reaction time required for the water treatment is long, and the amount of land consumption is large, and problems such as odors and noises occur incidentally, and it is not widely applied from small to large scale and low to high concentration. There was a problem of difficulty.
이에 본 발명은 상기한 종래의 문제점을 해결하기 위한 것으로 전기분해법과 생물막법을 효율적으로 결합하여 수중에 존재하는 주요 오염인자인 유기성 물질과 입자상 물질, 영양염류 등의 제거를 통하여 처리수를 재이용 가능한 등급으로 정화하면서도 소규모에서 대규모 및 저농도에서 고농도에 이르기까지 적용이 가능하도록 한 고도의 수처리방법 및 장치를 제공하는데 그 목적이 있다.Accordingly, the present invention is to solve the above-mentioned problems, and by combining the electrolysis method and the biofilm method efficiently, the treated water can be reused through the removal of organic substances, particulate matter, nutrients, etc., which are the main pollutants in water. Its purpose is to provide a highly water treatment method and apparatus that can be applied from a small scale to a large scale and low to high concentrations.

As shown in FIG. 2, the electrolysis device 31 according to the present invention applies current to the anode electrode 312 and the cathode electrode 313 outside the main body 317. An internal cathode electrode tube 314 and an inner cathode electrode tube 315 are formed in the power supply device 311 and the main body 317 to be charged with the electrodes opposite to the external electrodes 312 and 313. A fixing stand 316 is formed to fix the inner electrode tubes 315 and 3 16 at a predetermined distance from the outer electrode tubes 312 and 313.
상기와 같은 구성을 갖는 전기분해장치(31)는 전원공급장치(311)에 의해서 외부에 양극전극(312)과 음극전극(313)이 형성되고, 그 내부에 그와 반대되는 전극이 대전됨으로서 그 내부를 순환하는 오폐수의 처리가 빠른시간내에 처리될 수 있도록 함과 동시에 전극에 스케일이 끼지 않는다는 잇점이 있다.In the electrolysis device 31 having the above configuration, the anode electrode 312 and the cathode electrode 313 are formed on the outside by the power supply device 311, and the electrode opposite thereto is charged therein. The advantage is that the waste water circulating inside can be treated quickly, and the electrode is not scaled.
특히, 1차순환관(32)을 통해 연속적으로 순환되는 순환유체의 전기화학적 성질과 유체역학적 특성을 이용하여 전기분해조를 관로형 전기분해셀로 대체하고 대전극의 원리를 적용한 쌍극전극(Bipolar type)을 채택함으로써 수처리에 소요되는 에너지효율을 높일 수 있다는 장점이 있다.In particular, by using the electrochemical and hydrodynamic properties of the circulating fluid continuously circulated through the primary circulation tube 32, the bipolar electrode is applied to replace the electrolysis tank with a pipe type electrolysis cell and applies the principle of counter electrode. ), The energy efficiency required for water treatment can be improved.
이때 상기 전기분해셀의 표면에는 전극의 부식을 방지하기 위하여 그 표면에 이리듐(Ir, Iridium), 루테늄(Ru, Ruthenium) 혼합물질 또는 이리듐(Ir, Iridium)으로 Coating하여 종래 자주전극을 바꾸어주어야 하는 문제점을 해결하였다.At this time, the surface of the electrolysis cell should be coated with iridium (Ir, Iridium), ruthenium (Ru, Ruthenium) mixture or iridium (Ir, Iridium) on the surface of the electrode to prevent corrosion of the electrode. The problem was solved.
특히, 상기 전기분해장치(31)는 쌍극전극을 유도하는 관로형 전극방식을 채택하므로 오염원에 대한 균등한 처리기회를 제공하고 에너지 효율을 배가시켰으며, 또한 전극의 소모를 방지하고 처리효율을 고도화하기 위해 전해질을 폴리알루미늄계열의 무기고분자물질을 사용함으로써 미량의 전해질로도 처리가 극대화되고 전극스케일장애도 방지하고, 또 처리용량 증가 시 전극은 모듈방식으로 직렬 혹은 병렬로 연결할 수 있다.In particular, the electrolysis device 31 adopts a pipe-type electrode method that induces a bipolar electrode, thereby providing an equal treatment opportunity for pollutants and doubling energy efficiency, and also preventing electrode consumption and improving treatment efficiency. In order to use the polyaluminum-based inorganic polymer material for the electrolyte, the treatment is maximized even with a small amount of electrolyte and the electrode scale failure is prevented, and when the treatment capacity is increased, the electrodes can be connected in series or in parallel in a modular manner.

도3은 본 발명의 생물막분해조를 나타낸 개략도로서 상기 도3에서 보는 바와 같이 생물막분해조(51)는 생물막순환조(50)의 폐수를 순환관(52)를 통해 생물막분해조(51) 상단으로 이송시키고, 상단으로 이송된 폐수는 생물막여과재(511)를 거쳐 정화되며, 상기 생물막여과재(511)를 거친 처리수는 다시 재순환관(512)을 통해 생물막순환조(50)로 이송하게 된다.3 is a schematic view showing a biofilm digestion tank of the present invention, as shown in FIG. 3, the biofilm digestion tank 51 is an upper portion of the biofilm digestion tank 51 through a circulating pipe 52 for the wastewater of the biofilm circulation tank 50. The wastewater transported to the upper portion is purified through the biofilm filter material 511, and the treated water passed through the biofilm filter material 511 is transferred to the biofilm circulation tank 50 through the recirculation pipe 512.
상기 생물막분해조(51) 하단에는 처리과정에서 발생되는 슬러지를 농축조로 이송할 수 있도록 한 슬러지이송관(513)이 형성되며, 미설명부호는 스크린막(514)을 나타낸다.At the bottom of the biofilm digestion tank 51, a sludge conveying pipe 513 for transporting the sludge generated in the treatment process to the thickening tank is formed, and the reference numeral denotes the screen film 514.
상기 생물막 처리장치는 충전담체여과필터형으로 고속순환유속에 의해 처리가 이루어지며, 특수구조의 담체에 유체가 통과할 때 다양한 소용돌이가 형성되는 구조를 가지고 있으므로 입자상 물질의 억류효과가 탁월하고 고속순환 시에는 수류공진형 소용돌이가 형성된다.The biofilm treatment device is processed by a high speed circulation flow in the form of a charge carrier filtration filter, and has a structure in which various vortices are formed when a fluid passes through a carrier of a special structure, so that the detaining effect of particulate matter is excellent and a high speed circulation is possible. At the time of formation, a water resonant vortex is formed.
이때 여과방식은 상향류와 하향류가 있으며 필요 시 내부 폭기 혹은 외부폭기형 장치를 설치하여 산소공급을 할 수도 있다. 담체를 통과하는 적정 유속이 중요하며, 순환방식은 다양한 조합이 가능해진다. 특별한 경우가 아니고는 하향류 방식을 적용하는 것이 무난하다. 생물막 처리장치는 충전담체여과필터형으로 고속순환유속에 의해 처리가 이루어진다. 특수구조의 담체에 유체가 통과할 때 다양한 소용돌이가 형성되는 구조를 가지고 있으므로 입자상 물질의 억류효과가 탁월하고 고속순환 시에는 수류공진형 소용돌이가 형성된다.At this time, the filtration method is upflow and downflow, and if necessary, the internal aeration or external aeration type device may be installed to supply oxygen. The proper flow rate through the carrier is important, and various combinations of circulation methods are possible. Except in special cases, it is safe to apply the downflow method. Biofilm treatment device is a charge carrier filter type is processed by a high speed circulation flow rate. It has a structure in which various vortices are formed when the fluid passes through the carrier of special structure, and the detaining effect of particulate matter is excellent, and the water resonant type vortex is formed during high speed circulation.
상기 담체는 폴리비닐클로라이드를 주체로 한 특수소재(바이오세라믹 물질)를 혼합하여 가공한 것이므로 거의 영구적이며 역세정이 간편하고 경량이므로 충전층의 높이를 높게할 수 있어 공간효율과 여과특성을 크게 할 수 있다. 충전여상을 유체가 통과하는 방식은 상향류식과 하향류식이 있는데 처리특성은 큰 차이가 없으나 처리목적에 따라 적정방식을 적용한다.Since the carrier is processed by mixing a special material mainly composed of polyvinyl chloride (bioceramic material), it is almost permanent, easy to backwash, and lightweight, so that the height of the packed layer can be increased, thereby increasing space efficiency and filtration characteristics. Can be. Fluid flows through the filling bed in upflow and downflow, but there is no significant difference in treatment characteristics, but the proper method is applied according to the purpose of treatment.
