Description
본 발명은 응집침전공정 또는 활성슬러지공정등이 채택되는 하폐수처리장의 침전지(Clarifier)에 관한 것으로, 특히 침전지의 내부에 다수개의 경사판이 설치되어 설치공간과 소요부지를 줄이고 경사판의 경사면에 슬러지의 축적을 방지하여 경사판이 폐쇄되지 않도록 하는 폐쇄방지수단이 구비되는 경사판침전지에 관한 것이다.The present invention relates to a clarifier of a sewage treatment plant in which a flocculation sedimentation process or an activated sludge process is adopted. In particular, a plurality of inclined plates are installed inside the sedimentation basin to reduce installation space and required sites, and to accumulate sludge on the inclined surface of the inclined plate. It relates to an inclined plate needle battery provided with a closing preventing means for preventing the inclined plate is not closed.
우리나라의 대다수 하천들은 오염이 진행된 상태이며 국가에서 하폐수처리에 많은 예산을 투입하고 있으나, 국내의 하수도 보급율은 선진국에 비하여 낮은 수준을 면치 못하는 실정이다. 따라서 한정된 국가의 재원으로 하수도 보급율을 높히기 위해서는 경제적이며 효율적인 하폐수처리시스템의 개발 및 보급이 필요하다. 그러나 지금까지 사용되어온 종래의 하폐수처리시스템은 부지의 활용도가 낮고, 시설비 소요가 큰 문제점이 있으므로, 우리나라와 같이 토지가 귀한 곳에서는 설치공간과 부지면적이 작게 소요되는 하폐수처리시스템이 보급되어야 한다.Most of the streams in our country have been polluted and the state is spending a lot of money on wastewater treatment, but domestic sewage penetration rate is lower than that of developed countries. Therefore, in order to increase the distribution rate of sewage with finite countries, it is necessary to develop and disseminate an economic and efficient wastewater treatment system. However, the conventional sewage water treatment system that has been used so far has a low utilization of the site and requires a large cost of facilities. Therefore, a wastewater treatment system requiring a small installation space and a small area should be disseminated in a place where the land is precious.
하폐수처리시스템을 구성하는 단위공정 가운데 반응조의 경우 수리학적 체류시간에 의해 결정되는 소요체적을 충족하면 되므로 유효수심을 깊게 하여 소요부지면적을 감소시킬수 있다. 반면에 반응에 직접 기여하지 않고 단순히 고액분리기능만을 수행하는 침전지의 경우 수면적부하율에 의하여 결정되는 최소 수면적이 확보되어야 한다. 종래의 침전지는 부지면적을 크게 차지하게 되는데, 침강되는 입자들이 침전지의 수면에서부터 침전되어 수심이 깊은 침전지 하부까지 도달하기 위해서는 긴 시간이 소요되기 때문이다.Among the unit processes that constitute the sewage water treatment system, the reactor needs to meet the required volume determined by the hydraulic retention time, so that the effective depth can be deepened to reduce the required area. On the other hand, for sedimentation basins that do not directly contribute to the reaction but merely perform solid-liquid separation, the minimum surface area determined by the surface area load rate should be ensured. Conventional sedimentation basins occupy a large area, because the settling particles take a long time to settle from the surface of the sedimentation basin to reach the depth of the deep sedimentation basin.
그러나 침전지에 다수의 경사판을 설치하면, 침전되는 입자들이 경사판과 경사판의 간격에 의하여 형성되는 수직거리만큼만 침전하여 경사판 표면에 도달하면 침전이 완료된다. 이에 따라 경사판침전지에서는 침전에 소요되는 시간이 매우 짧게 되므로 경사판침전지의 수면적과 체적은 크게 축소될수 있다.However, if a plurality of inclined plate is installed in the sedimentation basin, the sedimentation particles are precipitated only by the vertical distance formed by the interval between the inclined plate and the inclined plate and the precipitation is completed when the inclined plate surface is reached. As a result, the time required for precipitation in the inclined plate needle battery is very short, so that the surface area and volume of the inclined plate needle battery can be greatly reduced.
예를 들어 설명하면, 침전지의 수면적부하율이 20m3/m2·일이 요구되고 소요처리유량은 10,000m3/일인 하폐수처리시설에서 일반침전지를 적용할 경우에는 수면적은 500m2(=10,000m3/일 ÷ 20m3/m2·일)가 소요된다.For example, if a sedimentation basin has a surface area load of 20 m 3 / m 2 · day and a required treatment flow rate of 10,000 m 3 / day, when the general sedimentation system is applied, the surface area is 500 m 2 (= 10,000). m 3 / day ÷ 20m 3 / m 2 · day).
그러나 3Mx 5M의 판 79매를 65° 기울어지게 수평간격 100mm로 설치하면 동일한 수면적부하율을 적용하고서도 경사판침전지에서 소요되는 수면적은 40m2(5m x 8m)에 불과하고 수직투영 면적은 46.5m2(5m x 9.3m)가 소요되므로 일반 침전지의 약 10%정도로 소요부지면적이 대폭 축소될수 있다.However, when 79 sheets of 3 M x 5 M are installed at a horizontal interval of 100 mm with an inclination of 65 °, the surface area consumed by the inclined plate needle battery is only 40 m 2 (5 m x 8 m), while applying the same surface area load rate. As it takes 46.5m 2 (5m x 9.3m), the required area can be greatly reduced to about 10% of the general sedimentation basin.
이와 같이 침전지에 다수의 경사판이 설치되는 경사판침전지를 적용하게 되면 침전지의 소요부지면적과 공간을 감소시킬수 있다. 그러나 침전물질이 활성슬러지 또는 고분자응집제가 투입된 응집물과 같은 점착성의 고형물인 경우 경사판에일부 퇴적되어 경사판사이의 공간을 폐쇄하게 된다. 이에 따라 경사판침전지는 지금까지 비점성고형물의 침전분리에만 제한적으로 사용되었으며, 처리유량이 가장 많은 도시하수처리시설에서는 채택되지 못하는 문제점이 있었다.In this way, when the inclined plate immersion battery having a plurality of inclined plates is installed in the sedimentation basin, the required area and space of the sedimentation basin can be reduced. However, if the precipitate is a sticky solid such as activated sludge or agglomerates into which a polymer coagulant is added, it is partially deposited on the inclined plate to close the space between the inclined plates. Accordingly, the inclined plate settling batteries have been used only for sedimentation separation of non-viscous solids until now, and there is a problem that they cannot be adopted in the city sewage treatment facilities having the largest flow rates.
본 발명은 상기한 제 문제점을 해소하기 위하여 안출된 것으로, 침전효율을 증대시키기 위하여 반응조에서 유입되는 난류상태의 고형물현탁혼합액이 정류상태로 유입되도록 하는 정류장치와 경사판사이의 공간이 폐쇄되지 않도록 경사면에 퇴적 또는 부착되는 슬러지를 제거시키는 폐쇄방지장치를 구비하여 부지소요면적과 건설비를 절감할수 있고 신규 하폐수처리시설에서는 물론 부지의 추가 확보가 곤란한 가동중인 하폐수시설의 용량증대 목적으로도 이용될수 있는 경사판침전지를 제공하고자 한다.The present invention has been made to solve the above problems, in order to increase the settling efficiency, the inclined surface so that the space between the stop and the inclined plate to the turbulent solid suspension mixture flowing from the reactor flows into the rectified state The inclined plate can be used for the purpose of increasing the capacity of the sewage treatment plant, which can be used for the new sewage treatment plant, as well as for the additional sewage treatment facilities. To provide a clarifier.
이와 같은 목적을 달성하기 위하여 본 발명에서는 다수개의 경사판을 일정한 간격으로 설치하여 경사판침전부를 구성하고, 상기 경사판침전부에는 정류수단과 폐쇄방지수단 그리고 슬러지유출방지수단이 구비된 상징수 유출부를 설치하여 경사판침전지를 구성하였다.In order to achieve the above object, in the present invention, a plurality of inclined plates are installed at regular intervals to form an inclined plate settled portion, and the inclined plate settled portion is provided with a symbol water outlet provided with rectifying means, a closing prevention means, and a sludge leakage preventing means. An inclined plate needle battery was constructed.
상기 경사판은 소요설치공간을 줄이기 위하여 수평방향으로 1회 이상 수회 절곡하고 경사각은 45°∼70°범위로 한다. 또한 산화구에 내장되는 침전지인 경우 중앙의 수직선을 중심으로 양방향으로 절곡된 경사판으로 구성하여 중앙부근에 1개 이상의 다이아몬드형 단면의 수로를 형성하게 되면 산화구내의 순환수류가 잘 통과되므로 수류저항을 감소시킬수 있게 되어 유리하다.The inclined plate is bent several times or more in the horizontal direction to reduce the required installation space, and the inclination angle is in the range of 45 ° to 70 °. In addition, in the case of the sedimentation basin embedded in the oxidizing sphere, it consists of inclined plates bent in both directions about the vertical line in the center, and if one or more diamond-shaped channels are formed near the center, the circulating water flow in the oxidizing sphere passes well, thus reducing the water flow resistance. It is advantageous to be able to.
상기 정류수단은 반응조에서 난류상태인 고형물현탁혼합액을 고액분리에 유리한 정류상태로 전환시켜서 상기 경사판침전부로 유입되도록 하고 침전슬러지가 원활하게 배출되도록 한다. 이와 같은 기능을 수행하는 상기 정류수단의 구성은 삼각형단면의 그레이팅, 슬러지유출구가 구비된 호퍼와 유입유공관등으로 구성될수 있다.The rectifying means converts the solid suspension mixture in a turbulent state into a rectified state favorable for solid-liquid separation in a reaction tank so as to flow into the inclined plate settled portion and to allow the sludge to be discharged smoothly. The configuration of the rectifying means for performing such a function may be composed of a grating of the triangular cross section, the hopper and the inlet oil pipe provided with the sludge outlet.
상기 폐쇄방지수단은 경사판에 슬러지가 부착되거나 퇴적되어 경사판사이의 공간이 폐쇄되는 것을 방지하기 위한 것으로, 상기 경사판침전부에 강한 와류를 형성하여 정류상태에서 상기 경사면에 퇴적되었던 슬러지를 와류에 의하여 수중에 부유시키게 된다. 폐쇄방지수단의 가동을 중지하면 부유되었던 슬러지는 다시 침전되어 침전지 하부로 배출되는 구조이다. 상기 폐쇄방지수단은 교반기, 수중포기기 또는 산기식 포기기등의 포기 또는 교반장치를 적용하거나 경사판을 진동시키는 바이브레이터를 적용할 수 있다.The closure preventing means is to prevent the sludge is attached or deposited on the inclined plate to prevent the space between the inclined plates to be closed. A strong vortex is formed in the inclined plate settled portion and the sludge deposited on the inclined surface in the rectified state is underwater. Floated on. The suspended sludge is precipitated again and discharged to the lower part of the sedimentation basin when the closing prevention means is stopped. The closing preventing means may be applied to aeration or agitator, such as a stirrer, aquatic equipment or aeration type agitator, or may be applied to a vibrator for vibrating the inclined plate.
상기 상징수유출부는 경사판침전부에서 고형물이 분리된 청정한 상징수를 집수하여 유출되도록 하며 수중오리피스, V-notch 월류웨어 등으로 구성될수 있다. 그러나 상기 폐쇄방지수단이 가동되는 동안에는 경사판침전부 전체에 슬러지가 부유되어 있으므로 상기 상징수유출부를 통하여 부유슬러지가 유출되게 된다. 따라서 부유슬러지가 침전될때까지 상기 상징수유출부에서는 외부로 유출이 이루어지지 않도록하는 슬러지유출방지수단을 구비하였다.The symbolic water outflow unit collects the clean symbolic water from which solids are separated from the inclined plate settled portion and flows out. The symbolic water outlet may be composed of an underwater orifice and a V-notch overflowware. However, since the sludge is suspended throughout the inclined plate settled portion while the closing preventing means is operated, the suspended sludge flows out through the symbol water outlet. Therefore, the sludge outflow prevention means was provided to prevent the outflow to the outside until the suspended sludge settled out.
상기 슬러지 유출방지수단은 폐쇄방지수단의 가동에 의하여 부유되는 슬러지가 침전될때까지 유출구를 밀봉시키는 장치와 상징수유출부를 인양하여 수면위로노출시키는 장치 또는 유출관을 일시적으로 폐쇄하는 밸브등을 사용할수 있으며 작동방법은 전동, 공압, 유압 또는 공기의 부력을 이용하여 자동화할 수 있다.The sludge outflow prevention means may use a device for sealing the outlet and a device for lifting the symbolic water outlet and exposing it to the surface until the sludge suspended by the operation of the closure prevention means or a valve for temporarily closing the outflow pipe. The method of operation can be automated using buoyancy of electric, pneumatic, hydraulic or air.

도시한 바와 같이 이 실시예는, 다수개의 경사판(1)이 일정한 간격으로 설치되어 구성되는 경사판침전부(11)와, 반응조로부터 유입되는 난류상태의 고형물현탁혼합액이 정류상태로 전환되어 상기 경사판침전부로 유입되도록 하고 침전슬러지가 원활하게 배출되도록 하는 정류수단이 구비되어 있고, 상기 경사판침전부의 폐쇄를 방지하기 위하여 상기 경사판에 퇴적되는 슬러지를 부유 또는 탈리시키는 폐쇄방지수단과, 상징수가 유출되도록 하는 수중오리피스(51)형태의 상징수유출부가 구성되는 점은 제1실시예에서와 동일하다.As shown in this embodiment, the inclined plate settled portion 11 is formed by a plurality of inclined plates 1 are provided at regular intervals, and the solid suspension mixture flowing in the turbulent state flowing from the reaction tank is converted into a rectified state, and the inclined plate settles. Rectification means is provided so as to flow into the rich and smoothly discharged sediment sludge, the closing preventing means for floating or detaching the sludge deposited on the inclined plate in order to prevent the closing of the inclined plate settled portion, and the water to let the symbolic water outflow The point where the symbolic water outlet portion in the form of the orifice 51 is configured is the same as in the first embodiment.
여기서, 상기 경사판침전부는 중앙의 수직선을 중심으로 양방향으로 절곡된 다수개의 경사판으로 구성하여 경사판침전부의 중앙부근에 1개 이상의 다이아몬드형 단면의 수로(12)가 구성되므로 침전지 내장형산화구에 적용할 경우 수두손실이 경감되므로 유리하다.Here, the inclined plate settled portion is composed of a plurality of inclined plate bent in both directions about the vertical line in the center to form a channel 12 of one or more diamond-shaped cross-section near the center of the inclined plate settled portion, when applied to the sedimentation built-in oxidizing sphere It is advantageous because losses are reduced.
상기 정류수단은 단면이 삼각형인 다수개의 그레이팅(31)으로 구성되고, 상기 그레이팅사이의 개구부를 통하여 고형물현탁혼합액이 경사판침전부로 유입되므로 반응조에서는 난류상태인 고형물현탁혼합액이 상기 그레이팅을 통과하면서 침전에 유리한 정류상태로 전환된다. 침전슬러지는 동일한 상기 그레이팅의 개구부를 통하여 침전지 밖으로 배출되는 구조이다.The rectifying means is composed of a plurality of gratings 31 having a triangular cross section, and the solid suspension mixture flows into the inclined plate settled portion through the openings between the gratings, so that the solid suspension mixture which is turbulent in the reaction tank passes through the grating. It is switched to an advantageous rectification state. The settling sludge is discharged out of the settling basin through the same opening of the grating.
이 실시예에서는 상기 폐쇄방지수단은 회전익(41), 회전익 케이싱(43), 구동모터(42) 및 공기공급관(44)으로 이루어지는 수중포기기로 구성하였다. 상기 경사판에 슬러지가 퇴적되면 상기 회전익이 회전하면서 공기를 송기하고 수중에 잠겨 있는 수류보충구(46)에서 흡입되어 수류보충관(45)을 통하여 이송된 수류도 함께 분사되어 발생되는 와류에 의하여 퇴적된 슬러지가 부유되므로 경사판의 폐쇄가 방지된다. 또한 상기 폐쇄방지수단은 공기공급관의 설치를 생략하여 공기공급이 이루어지지 않는 교반기로 구성하기도 한다.In this embodiment, the closing prevention means is composed of a water-foaming device consisting of a rotor blade 41, a rotor blade casing 43, a drive motor 42 and an air supply pipe 44. When the sludge is deposited on the inclined plate, the rotary blade rotates to send air and is sucked in the water supply port 46 which is immersed in water, and the water flow transferred through the water supply pipe 45 is also sprayed and deposited by vortices generated. Since the sludge is suspended, the closing of the inclined plate is prevented. In addition, the closing prevention means may be configured as a stirrer that does not supply the air by omitting the installation of the air supply pipe.
상기 폐쇄방지수단이 가동하게 되면 경사판에 퇴적되었던 슬러지가 부유하게 되므로 부유슬러지가 외부로 유출되지 않도록 상징수유출관(62)에 상징수유출제어밸브(64)를 구성하고, 슬러지가 침전될때까지 상징수유출관을 밀폐시키는 구조이다. 부유슬러지가 외부로 유출되지 않도록 상기 폐쇄방지수단이 가동되기전에 침전지의 수위를 상기 상징수유출구의 아래까지 낮추어두는 방법도 적용될수 있다.When the closing prevention means is activated, the sludge deposited on the inclined plate is suspended, so that the symbolic water discharge control valve 64 is formed in the symbolic water outlet pipe 62 so that the sludge is not leaked to the outside, until the sludge is settled. It is a structure to seal the water outlet pipe. A method of lowering the level of the sedimentation basin to the bottom of the symbolic water outlet may be applied before the closing prevention means is activated so that the suspended sludge does not leak out.
이 실시예에서와 같이 침전지로 유입되는 고형물현탁혼합액이 상기 삼각형단면의 그레이팅의 개구부로 유입되고 침전슬러지도 동일 개구부로 배출되는 경사판침전지는 산화구등의 반응조내부에 침적하여 설치하는 구조이다.As in this embodiment, the inclined plate settling battery in which the solid suspension mixture flowing into the settling basin is introduced into the opening of the grating of the triangular cross section and the settling sludge is also discharged into the same opening.
본 발명에 의한 정류 및 폐쇄방지수단이 구비되는 경사판침전지는 다음과 같은 효과를 얻을수 있다.An inclined plate needle battery provided with the rectifying and closing prevention means according to the present invention can obtain the following effects.
첫째, 설치공간과 부지소요면적이 적어 경제적인 경사판침전지가 점착성고형물의 침전에도 제한없이 적용될수 있다.First, the economical inclined plate needle battery can be applied to the precipitation of sticky solids without any installation space and site area.
둘째, 처리용량이 부족하고 증설을 위한 추가 부지의 확보가 어려운 하폐수처리시설의 용량도 쉽게 증대시킬수 있다.Second, the capacity of sewage treatment facilities, which have insufficient treatment capacity and difficult to secure additional sites for expansion, can also be easily increased.
세째, 산화구에 내장형침전지로 적용하게 되면 종래의 침전지내장형산화구에서보다 부지의 활용도가 높고 구조물공사비가 절감되며 슬러지 수집장치, 반송슬러지펌프 등 기계공사와 부수되는 전기계장공사가 생략되므로 시설비면에서 매우 경제적이다.Third, when applied as a built-in settler in the oxidizing sphere, the utilization of the site is higher than in the conventional sedimentation built-in oxidizing sphere, and the construction cost is reduced, and the electrical instrumentation accompanying the sludge collection device and the return sludge pump is omitted. It is economical.
