Description

활성오니 정화시설의 무침전 방류 방법 및 그 장치{Activated sludge sanitation facilities of no settlenent discharge method and the device}Activated sludge sanitation facilities of no settlenent discharge method and the device

본 발명은 활성오니 정화시설의 무침전 방류 방법 및 그 장치에 관한 것으로 보다 구체적으로는, 활성오니를 이용해 오,폐수를 정화하는 시설에서 활성오니에 의해 반응이 이루어진 오,폐수를 별도의 침전시간 및 공간이 필요없이 여과수단을 통해 여과하여 신속하게 방류할 수 있게 하므로서, 활성오니 정화시설의 오,폐수 처리에 소요되는 시간을 대폭 단축시켜 오,폐수의 정화능력을 극대화할 수 있게 한 것이다.The present invention relates to a non-precipitating discharge method and an apparatus of an activated sludge purification plant. More specifically, the sedimentation time of sewage and wastewater reacted by activated sludge in a facility for purifying wastewater and wastewater using activated sludge is settled separately. And since it can be quickly discharged by filtration through the filtration means without the need for space, the time required for the wastewater treatment of the active sludge purification facility can be significantly shortened to maximize the purification capacity of the wastewater.

오,폐수의 생물학적 산화법으로서 가장 일반적으로 활용되는 활성오니법은 오,폐수에 미생물을 투입하여 폭기조에서 폭기, 교반하여 오,폐수에 함유된 각종 오염물질을 미생물분해 하거나 또는 활성오니에 흡착시키므로서 오,폐수를 정화한 후 이를 첨부도면 도 1와 같이 별도의 침전조(80)에서 수 시간동안 침전시켜 정화된 처리수과 슬러지를 완전 분리한 후 침전조(80)의 바닥에 가라앉은 슬러지가 유입되지 않도록 침전조(80) 상부의 물을 방류하게 된다.Activated sludge method most commonly used as biological oxidation method of wastewater is by adding microorganisms to wastewater and wastewater, and aeration and stirring in aeration tanks to decompose various contaminants contained in wastewater and wastewater or to adsorb them into activated sludge. After purifying the waste water, it is settled for several hours in a separate sedimentation tank (80) as shown in FIG. 1 to completely separate the purified water and sludge so that the sludge that sinks to the bottom of the sedimentation tank (80) does not flow. The water of the upper part of the sedimentation tank 80 is discharged.

그런데 위와같은 일반적인 활성오니법의 경우 오,폐수와 활성오니를 반응시키기 위한 폭기조와, 반응이 완료된 후 발생하는 슬러지와 처리수를 완전히 분리하기위해 슬러지를 침전시키는 침전조(80)가 필수적이기 때문에 이들의 복수 설치에 따른 초기시설비가 많이 투입될 뿐 만 아니라, 침전조를 이용한 슬러지의 침전시에 슬러지와 처리수의 완전분리를 위한 침전시간이 장시간에 걸쳐서 소요되며 폭기조의 미생물상태에 따라 침전이 되지 않는 경우도 빈번히 발생하여 슬러지의 완전침전이 이루어지기전 까지는 침전조의 물을 방류할 수 없으므로 오,폐수의 정화처리에 많은 시간이 소요됨으로 인해 정화시설의 연속적이고 효율적인 운전이 불가능한 문제점이 있었다.However, in the case of the general activated sludge method as described above, the aeration tank for reacting the wastewater and the activated sludge, and the settling tank 80 for settling the sludge to completely separate the sludge and the treated water generated after the reaction are essential, Not only does the initial facility cost increase due to multiple installations, but the sedimentation time for sedimentation of sludge using sedimentation tank takes a long time for complete separation of sludge and treated water. In many cases, the sedimentation tank cannot be discharged until the sludge is completely settled, and thus, it takes a long time to purify wastewater and wastewater.

따라서, 본 발명은 위와 같은 종래의 여러가지 문제점들을 해소하기 위한 것으로서, 침전조의 물을 배출하는 배출관에 이물질을 걸러주는 여과수단과, 여과수단에 흡착된 슬러지와 같은 이물질을 제거해주는 청소수단을 갖추어 활성오니에 의해 반응이 완료된 오,폐수를 별도 침전 공정없이 바로 방류할 수 있게 하므로서 정화시설의 정화처리 능력을 극대화할 수 있게 한 것으로 이를 첨부된 도면에 의하여 보다 상세히 설명하면 다음과 같다.Therefore, the present invention is to solve the various problems as described above, and equipped with a filtration means for filtering foreign substances in the discharge pipe for discharging the water of the sedimentation tank, and a cleaning means for removing foreign substances such as sludge adsorbed to the filtration means. By allowing the sewage and wastewater of the reaction completed by sludge to be discharged immediately without a separate precipitation process, the purification treatment capacity of the purification facility can be maximized. This will be described in more detail with reference to the accompanying drawings.

오,폐수를 활성오니와 함께 반응조(10)에서 폭기, 교반하여 오,폐수에 함유된 각종 오염물질을 미생물분해하여 침전시키거나 활성오니에 흡착시키므로서 오,폐수를 정화하는 활성오니 정화공법에 있어서, 활성오니와 오,폐수의 반응이 이루어지는 반응조(10)에 배출관(20)을 설치하되, 배출관(20)에는 슬러지와 같은 이물질을 걸러주는 여과수단과, 이 여과수단에 흡착되는 이물질을 제거해주는 청소수단을 구비하여, 활성오니에 의해 반응이 완료된 오,폐수를 별도 침전 공정없이 여과수단을 이용해 이물질을 걸러낸 후 바로 방류할 수 있게 한 구성이다.In the activated sludge purification method, the wastewater is aerated and stirred in the reaction tank 10 together with the activated sludge to precipitate microorganisms to precipitate various contaminants contained in the wastewater, or to adsorb the activated sludge to purify the wastewater. In this case, the discharge pipe 20 is installed in the reaction tank 10 in which the reaction of the activated sludge and the wastewater is performed, and the discharge pipe 20 filters the foreign matter such as sludge and removes the foreign matter adsorbed by the filtering means. Equipped with a cleaning means, so that the wastewater, the reaction is completed by the active sludge is discharged immediately after filtering the foreign matter using a filtration means without a separate precipitation process.

또한, 위와 같은 구성을 위한 활성오니 정화시설의 무침전 방류장치의 구체적인 실시예를 설명하면 다음과 같다.In addition, the specific embodiment of the non-precipitating discharge device of the activated sludge purification plant for the above configuration is as follows.

오,폐수가 유입되어 폭기와 미생물분해가 병행되는 반응조(10)를 구비하는 공지의 활성오니 정화시설에 있어서, 상단연결부(21)를 펌프(60)와 연결한 배출관(20)의 하단부를 반응조(10) 내부에 투입하여 설치하되, 배출관(20)의 하단부에는 나사부(22a)를 구비한 확관부(22)를 형성하여 교체 가능한 여과부재(30)가 내장된 여과부재고정캡(32)을 나사부(22a)에 나사결합하고, 배출관(20)의 내부에는 에어노즐(40)을 형성하되, 에어노즐(40)의 에어공급부(42)는 배출관(20)의 외측에 형성하여 에어발생수단(50)과 연결한 구성이다.In a well-known active sludge purification facility having a reaction tank 10 in which wastewater flows in and wastewater flows in parallel with microbial decomposition, the lower end portion of the discharge pipe 20 connecting the upper connection portion 21 to the pump 60 is reacted. (10) Inserted and installed inside, but the lower end of the discharge pipe 20 to form an expansion pipe 22 having a threaded portion (22a) to replace the filter member fixing cap 32 with a built-in replaceable filtration member (30) Screwed to the threaded portion (22a), the air nozzle 40 is formed inside the discharge pipe 20, the air supply portion 42 of the air nozzle 40 is formed on the outside of the discharge pipe 20 to generate air ( It is connected to 50).

한편, 첨부도면 도 4는 본 발명의 또 다른 실시예를 나타낸 것으로서, 반응조(10) 내부에 복수개의 배출관(20)(20')을 설치하여 자동제어밸브(70)(71)에 의해 각각의 배출관(20)(20')의 작동을 제어하여 각 배출관(20)(20')의 교대 작동이 가능케 한 구성이다.On the other hand, Figure 4 shows another embodiment of the present invention, by installing a plurality of discharge pipes (20, 20 ') inside the reaction tank 10, each by an automatic control valve 70, 71 By controlling the operation of the discharge pipe (20, 20 ') is a configuration that allows the alternate operation of each discharge pipe (20, 20').

이와 같이 된 본 발명은 일반적인 활성오니 정화시설에 있어서, 오,폐수를 활성오니와 함께 반응조(10)에서 폭기, 교반하여 오,폐수에 함유된 각종 오염물질을 미생물분해 시키거나 또는 활성오니에 흡착시키므로서 오,폐수의 정화반응이 완료되면 별도의 침전시간없이 배출관(20)을 통해 정화된 처리수를 바로 배출할 수 있게 하므로서, 오,폐수의 정화처리에 걸리는 시간을 크게 단축시킬 수 있게 된다.In the present invention as described above, in a general activated sludge purification facility, a waste and waste water together with activated sludge are aerated and stirred in the reaction tank 10 to microbially decompose various contaminants contained in the wastewater and to be adsorbed onto the activated sludge. By doing so, when the purification reaction of the wastewater is completed, the treated water can be immediately discharged through the discharge pipe 20 without additional sedimentation time, thereby greatly reducing the time required for the purification process of the wastewater. .

즉 반응조(10)에 유입된 오,폐수에 함유된 각종 오염물질이 활성오니와 반응하여 슬리지와 정화처리된 처리수로 분리되면, 슬러지를 제외한 처리수를 배출관(20)을 통해 방류하게 되는데 반응조(10)에 설치된 배출관(20)에는 반응조(10) 내부의 슬러지와 같은 이물질을 걸러주는 여과수단을 갖추고있기 때문에 활성오니에 의해 반응이 완료되어 정화처리된 처리수에 슬러지가 혼합되어있다 하더라도, 여과수단에 의해 슬러지를 걸러서 처리수를 배출할 수 있기때문에 별도의 침전시간을 가질 필요가 없으므로 오,폐수의 정화처리에 소요되는 시간을 크게 단축시킬 수 있게 되는것이다.That is, when various contaminants contained in the wastewater and wastewater introduced into the reaction tank 10 react with the activated sludge and are separated into sludge and purified water, the treated water except the sludge is discharged through the discharge pipe 20. Since the discharge pipe 20 installed in the reaction tank 10 is equipped with a filtration means for filtering foreign substances such as sludge in the reaction tank 10, even though the sludge is mixed in the treated water after the reaction is completed by the activated sludge. Since the sludge is filtered by the filtration means, the treated water can be discharged, so it is not necessary to have a separate settling time, thereby greatly reducing the time required for the purification of the wastewater.

또한, 슬러지가 혼합된 처리수를 배출하는 과정에서 배출관(20)의 여과수단에 슬러지가 흡착되어 배출관(20)을 통한 처리수의 원활한 방류가 곤란할 경우에는 배출관(20)에 내부에 부설된 청소수단을 통해 여과수단에 흡착된 슬러지와 같은 각종 이물을 제거하므로서, 배출관(20)을 통한 원활한 방류가 지속될 수 있도록 하게 되는데, 이러한 배출관(20)의 여과수단이나 청소수단에 관한 장치들에 관한 실시예를 첨부된 도면에 의하여 보다 상세히 설명하면 다음과 같다.In addition, when sludge is adsorbed on the filtration means of the discharge pipe 20 in the process of discharging the treated water mixed with the sludge, it is difficult to smoothly discharge the treated water through the discharge pipe 20, the cleaning installed inside the discharge pipe 20 By removing various foreign substances such as sludge adsorbed to the filtering means through the means, it is possible to maintain a smooth discharge through the discharge pipe 20, the embodiment of the apparatus for the filtering means or cleaning means of such discharge pipe (20) An example will be described in more detail with reference to the accompanying drawings.

도 2와 같이 활성오니 정화시설에서 오,폐수가 유입되는 반응조(10)에는 펌프(60)와 연결된 배출관(20)의 단부를 반응조(10) 내부에 일정 깊이로 투입하여 설치하되, 배출관(20)의 단부에는 나사부(22a)를 형성한 확관부(22)를 형성하여 교체 가능한 여과부재(30)가 내장된 여과부재고정캡(32)을 나사부(22a)에 나사결합하고,배출관(20)의 내부에는 에어노즐(40)을 형성하되, 에어노즐(40)의 에어공급부(42)는 배출관(20)의 외측에 형성하여 에어발생수단(50)과 연결하게된다.As shown in FIG. 2, the end of the discharge pipe 20 connected to the pump 60 is installed in the reaction tank 10 to a predetermined depth in the reaction tank 10 into which the wastewater is introduced from the activated sludge purification facility. At the end of the screw), an expansion pipe portion 22 having a screw portion 22a is formed to screw the filtration member fixing cap 32 having the replaceable filtration member 30 therein into the screw portion 22a, and the discharge pipe 20 An air nozzle 40 is formed in the inside of the air supply unit 42 of the air nozzle 40 is formed outside the discharge pipe 20 is connected to the air generating means 50.

즉, 본 발명에서 여과수단의 경우 배출관(20)의 단부에 나사부(22a)를 형성한 확관부(22)를 형성하여 교체 가능한 여과부재(30)가 내장된 여과부재고정캡(32)을 나사부(22a)에 나사결합하므로서 반응조(10) 내부에서 슬러지와 혼합되어있는 처리수를 배출할때, 배출관(20)으로 처리수가 유입되는 과정에서 슬러지가 처리수의 흐름을 타고 처리수와 같이 배출관(20)쪽으로 유입되더라도 배출관(20)의 확관부(22)에 설치된 여과부재(30)가 이를 걸러주므로서, 정화처리가 완료된 청정한 처리수만을 배출할 수 있게 되는것이다.That is, in the present invention, in the case of the filtration means, the filtration member fixing cap 32 in which the replaceable filtration member 30 is formed by forming the expansion tube 22 having the screw portion 22a formed at the end of the discharge pipe 20 is screwed. When discharging the treated water mixed with the sludge in the reaction tank 10 by screwing to 22a, the sludge takes the flow of the treated water in the process of introducing the treated water into the discharge pipe 20 and discharges the pipe together with the treated water ( Even if it is introduced into the 20) by filtering the filter member 30 installed in the expansion pipe 22 of the discharge pipe 20, it is to be able to discharge only the clean treated water that has been purified.

이때, 여과부재(30)는 슬러지나 기타 이물을 효과적으로 걸러줄 수 있는 미세필터를 주로 사용하되, 그 재질은 현재 시중에서 시판되고 있는 다양한 재질의 필터를 적절하게 적용할 수 있음을 미리 밝혀두는 바이다.At this time, the filtration member 30 is mainly used a fine filter that can effectively filter sludge or other foreign matter, the material is to know in advance that can be appropriately applied to a filter of a variety of commercially available materials on the market .

한편, 여과부재(30)등으로 된 여과수단을 이용하여 슬러지를 걸러내고 처리수를 방류하더라도 처리수의 흐름에 의해 슬러지가 여과수단의 여과부재(30) 외부에 흡착되므로서 장시간동안 연속적으로 처리수를 방류하게되면, 여과부재(30)가 슬러지에 의해 막혀서 처리수의 방류가 곤란해지기때문에 이를 방지하기 위해 배출관(20)의 내부에는 청소수단을 구비하게되는데, 이 청소수단으로는 첨부도면 3도 과 같이 배출관(20)의 내부에 에어노즐(40)을 형성하되, 에어노즐(40)의 에어공급부(42)는 배출관(20)의 외측 상단부에 형성하여 콤프레셔와 같이 압축공기를 생산할 수 있는 에어발생수단(50)과 연결하므로서 압축공기를 배출관(20)의 확관부(22)에 설치된 여과부재(30) 내측으로 분출할 수 있게 되는데, 여과부재(30)의 외측에 다량의 슬러지가 흡착된 경우에 에어노즐(40)을 통해서 여과부재(30) 내측에서 여과부재(30) 외측으로 압축공기를 분출하게되면, 분출되는 공기의 압력에 의해 여과부재(30) 외측에 흡착되어있던 슬러지들이 떨어져나가기 때문에 여과부재(30)의 막힘을 방지할 수 있게 되는 것이다.On the other hand, even when the sludge is filtered out by using the filtering means such as the filtering member 30 and discharged the treated water, the sludge is adsorbed to the outside of the filtering member 30 of the filtering means by the flow of the treated water, thereby continuously processing for a long time. When the water is discharged, the filtration member 30 is blocked by the sludge, which makes it difficult to discharge the treated water. Thus, a cleaning means is provided inside the discharge pipe 20 to prevent this. The air nozzle 40 is formed in the discharge pipe 20 as shown in FIG. 3, but the air supply part 42 of the air nozzle 40 is formed at the upper upper end of the discharge pipe 20 to produce compressed air such as a compressor. By connecting with the air generating means 50, it is possible to eject the compressed air into the filtration member 30 installed in the expansion pipe portion 22 of the discharge pipe 20, a large amount of sludge outside the filtration member 30 If adsorbed When the compressed air is ejected from the inside of the filtering member 30 to the outside of the filtering member 30 through the nozzle 40, the sludge adsorbed to the outside of the filtering member 30 is separated by the pressure of the ejected air. It is to be able to prevent clogging of the filtering member (30).

아울러 첨부도면 도 4는 반응조(10) 내부에 복수개의 배출관(20)을 설치한 본 발명의 또 다른 실시예로서, 반응조(10)에 단일 배출관(20)을 설치할 경우에는 청소수단을 통해 여과부재(30)를 청소하는 동안에는 처리수의 정상적인 방류가 곤란하기 때문에 대용량의 활성오니 처리시설의 경우에는 보다 신속한 처리수의 방류를 위하여 복수개의 배출관(20)(20')을 자동제어밸브(70)(71)와 연결하여 설치하므로서, 일측 배출관(20)이 방류중일때 타측 배출관(20')의 여과부재를 청소하므로서, 처리수의 연속적인 방류가 이루어질 수 있기때문에 활성오니 처리시설을 이용한 대량의 오,폐수 정화시에 정화처리능력을 극대화할 수 있게 되는 것이다.In addition, Figure 4 is another embodiment of the present invention in which a plurality of discharge pipes 20 are installed in the reaction tank 10, in the case of installing a single discharge pipe 20 in the reaction tank 10 through the filtering means through the cleaning means (30) Since the normal discharge of the treated water is difficult during cleaning, in the case of a large-capacity activated sludge treatment plant, a plurality of discharge pipes (20) and (20 ') for automatic discharge of the treated water is automatically controlled by the valve (70). By installing in connection with (71), by cleaning the filtration member of the other discharge pipe (20 ') while the one discharge pipe (20) is discharged, because the continuous discharge of the treated water can be made a large amount using the sludge treatment facility It is possible to maximize the purification treatment capacity when the waste water purification.

따라서 본 발명은 활성오니를 이용한 오,폐수 처리시설에서 처리수의 침전과정없이도 처리수의 안전하고 신속한 방류가 가능케 되므로서, 오,폐수의 정화처리에 소요되는 시간을 혁신적으로 단축시켜 오,폐수 처리시설의 처리능력을 극대화할수 있을뿐 만 아니라, 처리수의 침전과 관련된 시설이 불필요하기 때문에 초기시설비나 운영비를 절감하므로서 매우 경제적인 이점이 있다.Therefore, the present invention enables safe and rapid discharge of treated water without sedimentation of treated water in the sewage and wastewater treatment facility using activated sludge, thereby innovatively shortening the time required for the purification process of wastewater and wastewater. In addition to maximizing the treatment capacity of the treatment plant, since there is no need for facilities related to sedimentation of the treated water, there is a very economical advantage by reducing the initial cost and operating costs.
