Description

침전효율을 높일 수 있는 침전지{SETTLING POND}Sedimentation basin to increase sedimentation efficiency {SETTLING POND}

본 발명은 침전지에 관한 것으로, 더욱 상세하게는 밀도류가 발생되어도 침전지 바닥에 침전된 슬러지가 부상하지 않도록 하며, 또한, 침전지에서 유동하는 상등수의 탁도와 플럭의 입자분포도에 따라 상등수의 체류시간을 조절할 수 있는 침전효율을 높일 수 있는 침전지에 관한 것이다.The present invention relates to a sedimentation basin, and more particularly, to prevent sludge deposited on the bottom of the sedimentation basin even when a density flow occurs, and to control the residence time of the supernatant according to the turbidity of the supernatant flowing in the sedimentation basin and the particle distribution of the flocs. The present invention relates to a sedimentation basin capable of increasing sedimentation efficiency.

현재 국내의 정수장에 적용하고 있는 여과방식은 대부분 급속여과방식이다.Most of the filtration systems currently applied to domestic water purification plants are rapid filtration.

급속여과방식에서 가장 중요한 공정은 응집,침전 및 여과공정이다. 완속여과법과 달리 제한된 공간에서 보다 많은 정수를 생산하기 위해서는 기계적 방법으로 응집공정에서 플럭을 최대한 단단하고 크게 생성해야 하며 침전공정에서는 응집공정에서 생성된 플럭을 최대한 중력식으로 가라앉게 할 수 수 있는 기능을 수행해야 하며 여과지에서는 큰 여과속도로 많은 정수를 생산해야한다. The most important processes in rapid filtration are flocculation, sedimentation and filtration. Unlike slow filtration, in order to produce more purified water in a limited space, the flocculation process has to produce flocs as hard and large as possible, and in the precipitation process, the flocculation process has the ability to sink the flocs generated by gravity as much as possible. Filter paper has to produce a lot of purified water with large filtration rate.

그러나 현재 많은 정수장에서는 밀도류에 의한 문제, 응집부 유입수로의 불균등한 유량분배문제 및 미세 플럭의 침전지 월류문제 등으로 관리상의 많은 어려 움을 겪고 있다. At present, however, many water treatment plants are experiencing difficulties in management due to problems such as density flows, uneven flow distribution to flocculation inflows, and overflow of fine floc ponds.

밀도류에 의한 문제는 원수의 탁도증대 및 온도변화 등의 이유로 침전지 내 평균유속보다 큰 유속의 밀도류가 침전지를 통과하게 되며 또한 침전지의 전단에서는 상향에서 하향으로 전개되고 침전지의 3분의2지점에서는 하향에서 상향으로 전개되는 특징이 있다.The problem caused by the density flow is that the density flow at the flow rate larger than the average flow velocity in the sedimentation basin passes through the sedimentation basin due to turbidity increase and temperature change of raw water. There is a feature that is developed upward.

상기와 같은 밀도류로 인해 응집효율이 저하됨은 물론이고 밀도류에 의한 단락류가 침전지에서 생겨 침전효율을 저하시킨다. 또한 밀도류로 인해 침전지의 바닥에 존재하는 슬러지가 침전지 상부로 재부상하는 현상도 발생하여 수질에 악 영향을 끼치며, 침전지 끝단에서는 미세 플럭이 침전지의 월류웨어를 월류하여 여과지로 유입되며 유입된 미세 플럭으로 인해 여과지의 여재가 폐색되어 여과지속시간을 저하시킨다. 여과지속시간의 저하는 여재의 효율향상을 위해 실시되는 역세척의 빈번한 실시를 유발하며 역세척의 빈번한 실시로 인해 여재의 마모율 증가 및 여재의 수명주기 단축으로 인해 여재교체공사를 시행하여 여재를 교체해야 하는 경우가 발생한다.Due to the density flow as described above, as well as the cohesive efficiency is lowered, a short circuit caused by the density flow occurs in the sedimentation basin, thereby lowering the precipitation efficiency. In addition, the sludge present at the bottom of the sedimentation basin re-emerges into the upper part of the sedimentation basin due to the density flow, which adversely affects the water quality.At the end of the sedimentation basin, the microfluid flows through the sewage overflow wear and flows into the filter paper. As a result, the media of the filter paper is blocked, thereby reducing the filter duration. Deterioration of the filtration time causes frequent backwashing to improve the efficiency of the media.Replacement of the media through the replacement of the media is carried out by increasing the wear rate of the media and reducing the life cycle of the media due to the frequent backwashing. There is a need to do it.

따라서 상기의 문제를 해결하기 위해서는 응집효율을 높여 최대한으로 플럭의 상태를 크고 단단하게 형성한 후 침전지에서 중력식으로 최대한 많이 침전시키고 침전지에서 여과지로 이송되는 상등수는 매우 탁도가 낮고 미세 플럭이 포함되지 않은 원수라야 한다.Therefore, in order to solve the above problems, the flocculation efficiency is increased to the maximum and the solid state is formed as large and hard as possible, and then the sedimentation basin is settled as much as possible by gravity, and the supernatant water transferred from the sedimentation basin to the filter is very low in turbidity and does not contain fine flocs. You must be your enemy.

또한 탁도가 낮고 미세 플럭이 포함되지 않은 침전지 상등수를 만들기 위해서는 농도차이 및 온도차이로 발생하는 밀도류를 효과적으로 제어할수 있어야 하며 응집효율 저하로 발생하는 미세 플럭을 제어하기 위해서는 침전지내에서의 체류시간을 증대시킴으로써 침전시킬수 있도록 하는 방안이 필요하다. In addition, in order to make sedimentation supernatant with low turbidity and no microfluid, it is necessary to effectively control the density flow caused by the concentration difference and the temperature difference, and to increase the residence time in the sedimentation basin to control the microfluid caused by the aggregation efficiency decrease. It is necessary to have a way to settle it.

도 1a와 도 1b는 종래 기술에 의한 침전지를 도시한 것으로, 이에 도시된 바와 같이, 취수장으로부터 취수한 원수는 약품 투입후 원수배관(100), 유량분배구(110), 응집지 유입밸브(111)를 통해 응집지(120)로 유입된다. 이때 응집지(120)에 설치된 응집기(121)에 의한 기계적인 교반을 이용하여 플럭을 형성시킨다. 응집지(120)에서 형성된 플럭은 침전지 전단의 정류벽(130)을 통해 침전지(140)로 이송되어 중력식으로 침전되고 침전지(140)의 상등수는 월류웨어(150)로 유출되어 상등수집수구(160)에 집수되고 침전지유출배관(170)을 통해 여과지로 이송된다. 이때 상등수 표면의 부유물질이 월류웨어(150)를 통과하는 것을 막기 위해 배플(151)이 설치된다. 상기와 같은 방식을 급속여과방식이라한다. 현재 국내의 대부분의 정수장은 급속여과방식에 의해 수돗물을 생산하고 있다. 그러나 원수의 탁도증대 및 온도변화 등의 이유로 밀도류가 발생하여 도 1b에서와 같이 침전지의 전단에서는 상향에서 하향으로 전개되고 침전지의 3분의 2지점에서는 하향에서 상향으로 전개되는 특징이 있다. 이와 같은 밀도류로 인해 침전지 바닥의 슬러지가 침전지 상부로 부상하여 수질을 악화시키고 밀도류로 인한 단락류가 발생하여 플럭이 서로 결합하여 침전지로 침전되지 못하고 미세 플럭이 월류웨어(150)를 통해 여과지로 누출되어 여과수명을 단축시키는 문제가 발생한다.Figure 1a and Figure 1b shows a sedimentation basin according to the prior art, as shown in this, the raw water taken from the intake is the raw water pipe 100, the flow distribution port 110, the flocculation pond inlet valve 111 after the chemical input Inflow to the flocculation paper 120 through the). At this time, the floc is formed by using mechanical agitation by the flocculator 121 installed in the flocculation paper 120. The floc formed in the flocculation basin 120 is transferred to the sedimentation basin 140 through the rectifying wall 130 at the front end of the sedimentation basin, and is settled by gravity, and the supernatant of the sedimentation basin 140 is discharged to the overflowware 150 to collect the supernatant collecting holes 160. It is collected in and is transferred to the filter paper through the sedimentation outlet pipe (170). At this time, the baffle 151 is installed to prevent the suspended solids on the surface of the supernatant from passing through the overflowware 150. Such a method is called a rapid filtration method. At present, most domestic water treatment plants produce tap water by rapid filtration. However, due to the increase in turbidity of the raw water and the temperature change, the density flow is generated, and as shown in FIG. 1B, it is developed upward from downward in the front of the sedimentation basin and downward from upward in two-thirds of the sedimentation basin. Due to the density flow, sludge at the bottom of the sedimentation basin rises to the upper part of the sedimentation basin and worsens the water quality, and short-circuit flow due to the density flow causes the flocs to bind to each other and do not settle into the sedimentation basin. This results in a problem of shortening the filtration life.

본 발명은 상술한 바와 같은 문제점을 해결하기 위한 것으로, 저수온시나 고탁도시 발생하는 밀도류를 제어하여 침전지 하부의 슬러지가 부상하지 않도록 함으로써 수질오염을 방지할 수 있는 침전효율을 높일 수 있는 침전지를 제공하려는데 그 목적이 있다.The present invention is to solve the problems as described above, by providing a sedimentation basin to increase the sedimentation efficiency that can prevent water pollution by controlling the flow of density generated during low water temperature or high turbidity so that the sludge of the sedimentation basin does not float I want to do that.

그리고, 본 발명의 다른 목적은 침전지에서 유동하는 상등수의 탁도와 플럭의 입자분포도에 따라 상등수의 체류시간을 조절하여 침전효율을 높이려는데 있다.Another object of the present invention is to increase the precipitation efficiency by adjusting the residence time of the supernatant according to the turbidity of the supernatant flowing in the sedimentation basin and the particle distribution of the floc.

전술한 바와 같은 목적을 달성하기 위한 본 발명에 의한 침전효율을 높일 수 있는 침전지는, 침전지에 유입되는 물의 상층부와 하층부의 온도를 각각 감지하는 온도센서, 상기 침전지에 설치되어 필요시 상기 침전지 바닥에 침전된 슬러지가 부상하지 않도록 잠기는 유체흐름 제어수단, 상기 온도센서의 감지값의 차이와 기준치를 비교하여 상기 유체흐름 제어수단의 가동을 제어하는 제어부를 포함하여 구성된 것을 특징으로 한다.The sedimentation basin can increase the sedimentation efficiency according to the present invention for achieving the above object, a temperature sensor for sensing the temperature of the upper and lower portions of the water flowing into the sedimentation basin, respectively, installed in the sedimentation basin on the bottom of the sedimentation basin if necessary And a control unit for controlling the operation of the fluid flow control means by comparing the difference between the detected value of the temperature sensor and a reference value so as to prevent the sludge from being precipitated.

그리고, 본 발명은 침전지에서 유출되는 상등수의 탁도와 플럭의 입자분포도에 따라 상기 상등수의 체류시간을 조절하는 제어부, 상기 제어부의 제어에 따라 상기 웨어의 높이를 조절하는 높이조절수단을 포함하여 구성된 것을 특징으로 한다.And, the present invention is configured to include a control unit for adjusting the residence time of the supernatant according to the turbidity of the supernatant water flowing out of the sedimentation basin and the particle distribution of the flocks, the height adjusting means for adjusting the height of the wear under the control of the controller. It features.

본 발명에 의한 침전효율을 높일 수 있는 침전지에 의하면, 고탁도 및 저수온시 발생하는 밀도류를 제어하여 밀도류 발생시 일어나는 침전지 바닥에 있는 슬러지가 부상하여 수질에 악영향을 끼치는 문제를 해결할 수 있으며, 또한 밀도류에 의해 발생하는 단락류에 의한 침전효율저하 및 미세플럭의 침전웨어 누출현상을 제어하여 침전지에서 여과지로 이송되는 침전지 상등수의 탁도를 최대한으로 낮춰 여과지의 여과지속시간을 증대시키는 효과가 있다. 즉 침전지 상등수의 탁도를 최대한으로 낮춤으로써 여과지속시간을 증대시키고 여과지속시간이 증대될수록 여과 효율은 높아져 높은 수질의 많은 정수를 생산할수 있다. According to the sedimentation basin which can increase the sedimentation efficiency according to the present invention, by controlling the density flow generated at high turbidity and low water temperature, the sludge at the bottom of the sedimentation basin generated when the density flow occurs can be solved and adversely affect the water quality. The sedimentation efficiency decrease due to the short-circuit flow and sediment wear leakage of the fine flocs are controlled to reduce the turbidity of the supernatant of the sedimentation basin water transferred from the sedimentation basin to the filter cell to the maximum, thereby increasing the filter duration of the filter paper. That is, by lowering the turbidity of the sedimentation supernatant to the maximum, the filtration duration is increased, and as the filtration duration is increased, the filtration efficiency is increased to produce a large number of high-quality purified water.

또한 침전지 상등수의 탁도를 낮춤으로써 여과지 유출탁도도 쉽게 낮출 수 있으며 이는 여과지 유출수에 시행하는 염소처리공정에서 탁도가 높을수록 많은 염소투입량을 요구함으로써 발생하는 트리할로메탄 등 염소소독부산물의 생성을 방지하는 부수적인 효과도 있다. In addition, by lowering the turbidity of the sedimentation supernatant, the filter runoff turbidity can be easily lowered, which prevents the generation of chlorine disinfection by-products such as trihalomethane, which is generated by requiring more chlorine input in the chlorine treatment process applied to the effluent. There are also side effects.

본 발명을 설명하기 전에 종래 기술과 동일한 구성요소에 대해서는 종래와 동일 부호를 설명하며 그 구성에 대한 구체적인 설명은 생략하기로 한다.Before describing the present invention, the same components as in the prior art will be described with the same reference numerals as in the prior art, and a detailed description thereof will be omitted.

도 2a와 도 2b는 각각 본 발명에 의한 침전효율을 높일 수 있는 침전지의 평면도와 측면도로, 본 발명에 의한 침전효율을 높일 수 있는 침전지(140)는, 응집지(120)에서 응집기(121)에 의해 형성된 플럭이 정류벽(130)을 통해 유입되며, 이 플럭을 중력식으로 침전시켜 상등수는 웰류웨어(150)로 유출되도록 함과 아울러 슬러지를 침전시키는 침전지 본체, 밀도류에 의한 슬러지의 부상을 막기 위하여 온도센서(240-1)(240-2), 유체흐름 제어장치(200) 및 웨어높이조절장치(300)를 갖는다.2A and 2B are a plan view and a side view of a sedimentation basin capable of increasing sedimentation efficiency according to the present invention, respectively. The floc formed by) is introduced through the rectifying wall 130, and the floc is gravity-sedimented so that the supernatant flows out into the wellware 150, and the sedimentation basin body which precipitates the sludge and rise of sludge due to the density flow. In order to prevent the temperature sensor (240-1) (240-2), fluid flow control device 200 and wear height adjusting device (300).

온도센서(240-1)(240-2)는 응집지(120)와 침전지(140) 사이의 정류벽(130)의 상하부에 각각 설치되어 정류벽(130)을 통과하여 침전지(140)로 유입되는 원수의 상층부와 하층부의 온도를 각각 감지하여 제어부(400)로 송신한다.The temperature sensors 240-1 and 240-2 are respectively installed at upper and lower portions of the rectifying wall 130 between the flocculating paper 120 and the settling chamber 140, and flow through the rectifying wall 130 to the settling chamber 140. The temperature of the upper and lower layers of the raw water is sensed and transmitted to the controller 400.

제어부(400)는 온도센서(240-1)(240-2)로부터 송신된 상층부와 하층부의 온도를 비교하여 유체흐름 제어장치(200)의 구동을 제어한다.The controller 400 controls the driving of the fluid flow control apparatus 200 by comparing the temperatures of the upper and lower layers transmitted from the temperature sensors 240-1 and 240-2.

간략히 설명하면, 상층부와 하층부의 온도가차 설정값 이하일 경우에는 유체흐름제어장치(200)는 T자형으로 설치된 기존의 형태(물의 흐름을 간섭하지 않는 형태)를 유지함과 동시에 유체흐름제어장치(200)에 설치되며 다수의 정류공을 갖는 중간 정류벽(230)을 이용 침전효율을 증대시킨다. 즉 침전지(140) 전단에 유입되는 원수의 상층부와 하층부의 온도차이가 없거나 미비한 경우에는 유체흐름 제어장치(200)는 작동하지 않고 단지 유체흐름제어장치(200)가 설치된 중간정류벽(230)만 이용하여 단락류 발생을 억제하고 난류 발생을 억제하여 침전효율을 증대시킨다. 반대로, 상층부와 하층부의 온도차가 설정값 이상일 경우에는 유체흐름 제어장치(200)는 침전지(140)에 잠겨 물의 흐름을 제어한다.Briefly, if the temperature of the upper layer and the lower layer is less than the difference set value, the fluid flow control device 200 maintains the existing form (that does not interfere with the flow of water) installed in the T-shape and at the same time the fluid flow control device 200 Installed in the intermediate rectifying wall 230 having a plurality of rectifying holes to increase the precipitation efficiency. That is, when there is no or inadequate temperature difference between the upper and lower portions of the raw water flowing into the sedimentation basin 140, the fluid flow control device 200 does not operate but only the intermediate rectification wall 230 in which the fluid flow control device 200 is installed. It is used to suppress the occurrence of short-circuit and to suppress the occurrence of turbulence to increase the precipitation efficiency. On the contrary, when the temperature difference between the upper layer and the lower layer is more than the set value, the fluid flow control apparatus 200 is locked to the settling basin 140 to control the flow of water.

도 3a와 도 3b에서 보이는 것처럼, 유체흐름 제어장치(200)는, 제어부(400)의 제어를 받아 구동하는 구동부(210) 및 이 구동부(210)의 구동에 의해 작동하여 물의 흐름을 제어하는 제1,2유체흐름 제어판(220)(220a)으로 구성된다. 유체흐름 제어판(220)(220a)은 도 3b 기준 중간 정류벽(230)을 중심으로 하여 좌우 양측에 각각 단부가 구동부 베드(217)에 회전 가능하게 설치된다.As shown in FIG. 3A and FIG. 3B, the fluid flow control apparatus 200 includes a driving unit 210 driven under the control of the control unit 400 and a driving unit controlled by the driving unit 210 to control the flow of water. 1,2 fluid flow control panels 220, 220a. The fluid flow control panels 220 and 220a are rotatably installed at both ends of the driving bed 217 on both left and right sides of the intermediate rectifying wall 230 of FIG. 3B.

도 4에서와 같이, 구동부(210)는 중간 정류벽(230)(도 3b 참고) 상부에 형성된 구동부 베드(217) 상에 구축되는 것으로, 전동기(211), 전동기(211)에 축 결합되어 회전하는 스프로켓(212), 스프로켓(212)과 함께 회전하는 드럼(214,216)(유체흐름 제어판(220)의 폭이 넓으므로 유체흐름 제어판(220)의 양측에 각각 대응됨), 드럼(214,216)에 각각 감기며 유체흐름 제어판(220)에 연결되어 드럼(214,216)의 회전시 드럼(214,216)에 감기거나 풀려 제1유체흐름 제어판(220)을 구동하는 와이어(221)로 구성된다. 이상은 제1유체흐름 제어판(220)에 관련된 구성을 설명한 것이며, 제2유체흐름 제어판(220a)은 제1유체흐름 제어판(220)과 동일하게 스프로켓(212a), 드럼(214a,216a), 와이어(221a)로 구동된다.As shown in FIG. 4, the driving unit 210 is constructed on the driving unit bed 217 formed on the intermediate rectifying wall 230 (see FIG. 3B), and is coupled to the motor 211 and the motor 211 to rotate.
