Abstract
근래에는 폐수를 열매체를 이용하여 폐수를 농축시켜서 응축시키거나, 대기로 방출하는 시설을 많이 선호하고 있다. 그러나 폐수내에 휘발성이 많은 용제류가 대다수 포함되어 있으므로 냉각시켜 응축수로 처리할 경우 응축수 내의 휘발물질인 메탄올, 에탄올, 벤젠, 토루엔 등 용제류가 과량 물과 함께 응축되어 COD, BOD 등 오염물질이 근본적으로 처리가 불가능하고, 응축을 시키지 않고 직접 농축기나 드럼 드라이어 등으로 증발시켜 대기로 방출할 경우 휘발성 물질중 암모니아, 황화수소 등 용제류의 악취물질이 그대로 대기로 방출되기 때문에 냄새로 인한 공해로 많은 민원을 일으키고 있는 현실이다.In recent years, wastewater is preferred to facilities that concentrate wastewater by using a heating medium and condense it or discharge it to the atmosphere. However, because most of the volatile solvents are contained in the wastewater, when it is cooled and treated with condensed water, solvents such as methanol, ethanol, benzene, and toluene, which are volatile substances in the condensed water, are condensed together with the excess water and pollutants such as COD and BOD If the volatiles are released into the atmosphere by directly concentrating them without condensation and evaporating with a condenser or a drum dryer, the odorous substances of solvents such as ammonia and hydrogen sulfide are released into the atmosphere as they are, It is a reality that causes complaints.
본 발명은 이러한 문제점을 해결하기 위해서 폐수중에 함유된 물질중 용제류나 저비점상승의 물질들을 먼저 처리하여 용제류는 재생하여 연료로 사용하고 비응축물질은 따로 액티브카본이나 촉매를 이용해서 처리한 후, 증발농축기에 투입하여 응축시킬 경우 수질이 현격하게 좋아져 물을 재사용할 수 있고, 농축기나 드럼 드라이어 등으로 처리하여 대기로 증기를 방출할 경우에는 냄새가 거의 제거된 상태로 방출되어 냄새로 인한 문제 해결을 위한 장치를 제공코저 한 것이다.In order to solve this problem, the present invention proposes a method of treating a solvent or a material having a low boiling point by first treating a substance contained in wastewater, regenerating the solvent, and treating the non-condensed substance using active carbon or a catalyst, When condensed into an evaporator, the water quality is remarkably improved and water can be reused. When steam is discharged to the atmosphere by treatment with a concentrator or a drum drier, the odor is discharged with almost no smell, And to provide a device for this.

본 발명의 폐수를 가열하여 수분을 증발시키고 스러지만을 농축하여 처리하는 증발 농축 폐수처리장치에 있어서 증발수분에서 발생되는 냄새를 제거하고 또 폐수에 함유된 용제를 회수키 위한 장치를 제공코저 한 것이다.There is provided an apparatus for removing odor generated from evaporated water and recovering a solvent contained in wastewater in an evaporated concentrated wastewater treatment apparatus for treating wastewater according to the present invention by evaporating water and concentrating the wastewater .
근래 산업의 대규모로 인하여 발생되는 폐수 또한 대량이 되어 이러한 다량의 폐수는 그 처리가 용이치 아니하여 증발 농축을 이용한 물리적 처리방법이 가장 능률적이 되어 많은 산업체에서 선호하고 있는 실정이다.In recent years, a large amount of wastewater generated from a large scale of the industry has become a large quantity, and such a large amount of wastewater is not suitable for the treatment thereof, and the physical treatment method using the evaporation concentration is the most efficient method.
그러나 이러한 증발방법에 의한 폐수처리는 폐수에 함유된 휘발성의 용제류가 포함되어 있는 것이므로 폐수의 증발수를 냉각시켜 응축수로 처리하는 경우 응축수 내에 휘발물질인 메탄올, 에탄올, 벤젠 톨루엔 등 용제류가 다량 증기와 함께 응축되면 COD, BOD 등의 문제가 발생되어 오염 물질이 근본적으로 처리가 불가능하고 증발수를 응축시키지 아니하고 대기로 방출할 경우 휘발성 물질에 의한 대기오염은 물론 암모니아, 황화수소 등 용제류의 악취물질이 그대로 대기중에 방출되기 때문에 심한 냄새로 인한 공해와 폐수처리에 따른 민원의 원인이 되어 왔던 것이다.However, since the wastewater treatment by the evaporation method includes volatile solvents contained in the wastewater, when the evaporation water of the wastewater is cooled and treated with the condensed water, a large amount of volatile substances such as methanol, ethanol, and benzene toluene If condensation occurs together with steam, problems such as COD and BOD are generated, so that the pollutants can not be treated fundamentally, and when they are discharged into the air without condensing the evaporated water, not only air pollution caused by volatile substances but also odor of ammonia, Because the substance is released into the atmosphere as it is, it has been the source of complaints due to pollution and wastewater treatment due to the strong smell.
본 발명은 이러한 문제점을 해결키 위한 장치를 제공코저 한 것으로서 이하 첨부된 도면에 의해 설명하면,BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings,
폐수탱크(1)의 원폐수가 펌프(2)에 의해 압상되어 열교환기(3)를 거쳐 가열기(4)에서 가열되어 처리탱크(5) 상부에 투입하도록 하고 처리탱크(5)는 내부에 수개의분사구를 가진 격판(15)과 하부에 보유부(55) 및 하단에 배수구(65)를 갖고 있으며 보유부(55) 측면상하에 유통구를 구비하여 측면에 설치된 가열기(6)를 장착하며 처리탱크(5) 상측 증기배출구는 열교환기(3)와 연결된 뒤 화학처리기(7)를 거쳐 외부와 연통되도록 구성된 것이다.The raw wastewater of the wastewater tank 1 is pushed up by the pump 2 and heated by the heater 4 through the heat exchanger 3 to be introduced into the upper part of the treatment tank 5, And a heater 6 provided on the side surface of the holding portion 55 and having a flow hole at the upper and lower sides of the holding portion 55. The heaters 6, The upper steam outlet of the tank 5 is connected to the heat exchanger 3 and is configured to communicate with the outside through the chemical processor 7. [
이와같이 된 본 발명은 사용상황과 작용효과를 설명하면As described above, according to the present invention,
폐수탱크(1)에 모인 원폐수는 펌프(2)에 의해 압상 진출되어 열교환기(3)를 지나면서 1차 가온(가온에너지는 후술합니다)된 뒤 가열기(4)를 지나면서 충분히 가열되어(통상 90~95 ℃) 처리탱크(5) 상측에 형성된 투입구에 투입되어 내부로 하강하게 된다.The raw wastewater collected in the wastewater tank 1 is advanced by the pump 2 in a pressurized state and passes through the heat exchanger 3 to be heated (the heating energy will be described later) Usually 90 to 95 DEG C), and is introduced into the inlet port formed on the upper side of the treatment tank 5 and descends to the inside.
한편 처리탱크(5) 내에는 일측에 폐수통로가 있고 전체에 분사구가 있는 격판(15)가 형성되어 있는데 이 격판(15)의 최상측에 진입된 가온 폐수가 낙하하게 되면 순차적으로 하강하게 되는데 격판의 폐수통로측에는 폐수가 흐르면서 분사구측에서는 폐수가 분사되므로 처리탱크 내부의 상측 격판(15)간에는 폐수 분사구가 커튼을 형성하게 되며 낙하되면서 가온되어 폐수에 포함된 용제류나 저비점상의 물질은 증발되게 되고 용제 등이 제거된 폐수상태로 하측 보유부(55)에 모이게 된다.On the other hand, in the treatment tank 5, there is provided a diaphragm 15 having a wastewater passage on one side and an injection port as a whole. When the warmed wastewater entering the uppermost side of the diaphragm 15 falls, The wastewater flows into the wastewater passage side and the wastewater is sprayed from the jetting port side. Therefore, the wastewater jetting port forms a curtain between the upper side diaphragms 15 inside the treatment tank, and the wastewater is heated while being dropped to evaporate the solvent or low boiling point material contained in the wastewater. And collected in the lower holding portion 55 in the state of the removed wastewater.
한편 보유부(55) 측면에는 가열기(6)가 장착되어 있어 보유부(55)의 폐수를 가열하게 되며 가열된 폐수는 자연 대류현상에 의해 보유부(55) 내 진입되고 새로운 폐수가 가열기(6) 내로 진입되게 되어 보유부(55) 내부 폐수는 고온(통상 100 ℃ 정도)으로 가열되게 된다.On the other hand, the heater 6 is mounted on the side of the holding part 55 to heat the wastewater of the holding part 55. The heated wastewater enters the holding part 55 by natural convection and the new wastewater flows into the heater 6 So that the wastewater in the holding portion 55 is heated to a high temperature (usually about 100 ° C).
보유부(55) 내부의 폐수가 가열되면 폐수가 낙하시 미처 증발되지 아니한 저비점상 물질들은 증발현상이 일어나 발생된 증기는 상측으로 향하게 되면서 낙하폐수를 가열하고 최상측의 배출구를 통하여 열교환기(3)의 열원으로 사용된 뒤 응축된 용제 및 응축수는 하측의 배출구로 출수되고 비응축성 기체나 악취는 상측의 출구를 지나 액티브 카본이나 촉매를 이용하여 처리된 뒤 대기중에 방출되게 된다.When the wastewater in the holding part 55 is heated, the low boiling point materials that have not evaporated when the wastewater is dropped are evaporated, and the generated steam is directed upward, and the falling wastewater is heated and discharged through the heat exchanger 3 ), The condensed solvent and condensate are discharged to the lower outlet, and the non-condensable gas or odor passes through the upper outlet and is treated with active carbon or catalyst and then released into the atmosphere.
그리고 얻어진 용제 및 응축수는 용제와 응축수를 분리하여 용제는 가열기의 열원으로 사용될 수 있게 된다.The solvent and the condensed water are separated from the solvent and the condensed water so that the solvent can be used as a heat source of the heater.
한편 용제 등이 증발된 원폐수는 보유부(55) 하단에 설치된 배출구를 통하여 여타한 폐수처리장치에 공급되어 처리케 된다.On the other hand, the raw wastewater in which the solvent or the like has evaporated is supplied to the other wastewater treatment device through an outlet provided at the lower end of the holding portion 55 to be treated.
이와같은 본 발명은 폐수에 함유된 용제 및 악취를 극히 간단한 구조와 시설로 간단히 처리한 뒤 용제는 연료로 사용할 수 있게 하고 용제와 냄새가 제거된 폐수만을 타 폐수처리장치에 공급할 수 있는 것이므로 폐수처리장치가 설치된 폐수처리 장소에 설치하므로서 폐자원을 활용하고 민원을 없앨 수 있는 매우 유용한 효과를 제공하게 된다.In the present invention, since the solvent and odor contained in the wastewater can be simply treated with an extremely simple structure and facilities, the solvent can be used as fuel, and only the wastewater from which the solvent and odor are removed can be supplied to the other wastewater treatment apparatus. It is installed in the wastewater treatment plant where the apparatus is installed, thereby providing a very useful effect of utilizing waste resources and eliminating complaints.
