본 고안은 수원지 또는 정수장에서 상수도를 생산하는 공정에 있어서, 급속여과지를 역세척 할 때 지(地) 내의 깨끗한 저탁도수와 고탁도수를 급속여과지의 역세척 공정과 회수조의 유입밸브를 콤바인드 콘트롤(Combined Control)에 의해서 자동분리 할수 있도록 한 시스템에 관한 것으로 특히 재처리 설비의 용량감소와 깨끗한 저탁도수의 분리회수로 인한 에너지의 절약 및 건설, 유지 관리비를 절약할 수 있도록 한 것이다.The present invention combines clean low turbidity water and high turbidity water into the backwashing process of the fast filtration paper and the inlet valve of the recovery tank in the process of producing tap water at the source or water purification plant. It is a system that enables automatic separation by combined control, especially energy saving, construction and maintenance costs due to reduced capacity of reprocessing facilities and separation of clean low turbidity water.

일반적으로 물 역세척 방식이나 공기, 물 겸용 역세척 방식을 구비한 급속여과지에 있어서는 비교적 굵은 입상층에 빠른 유속으로 물을 통과시켜 여재 표면에서의 체 작용과 여층의 역류가 여과작용의 주요인으로서 현탁물질을 제거하게 되는 효과적인 여과이고 이를 계속 유지하기 위한 재생기능으로 분류가 되며 이 재생기능을 급속여과지의 역세척이라 한다.In general, in the case of rapid filter paper equipped with a water backwash method or an air and water backwash method, water is passed through a relatively thick granular layer at a high flow rate, so that the sieve action on the surface of the media and the backflow of the filter layer are suspended as the main factors of the filtration action. It is an effective filtration that removes material and is classified as a regeneration function to maintain it. This regeneration function is called back filtration of rapid filter paper.

급속 여과지의 역세척은 여과사층 내에 억류되어 있는 탈질류를 제거하기 위하여 여과지의 하부로부터 물(또는 물과 공기)을 역으로 공급하여 세척을 행하게 된다.Backwashing of the quick filter paper is performed by supplying water (or water and air) back from the bottom of the filter paper to remove denitrification accumulated in the filter sand layer.

이와같은 역세척을 위해서는 여과지내의 최대수위를 역세척 수위까지 여과지 내의 저탁수도(침전수)를 배출시킨 다음, 역세척을 행해야 하므로서 이때 배출되는 저탁도수와 역세척시 배출되는 고탁수도와는 동일관로를 통하여 배출되며 이를 분리하여 저탁도수는 재처리 공정을 거치지 않고 직접 회수하여 재사용하며 고탁도수만을 재처리하도록 하는 것이 바람직하다.For such backwashing, the low water level (precipitated water) in the filter paper must be discharged to the maximum water level in the filter paper and then backwashed. Therefore, the low turbidity water discharged at this time and the high turbidity water discharged during backwashing It is preferable to discharge the same through the same pipe and separate it so that the low turbidity water can be directly recovered and reused without going through the reprocessing process and reprocess only the high turbidity water.

이와 같이 저탁도수와 고탁도수를 분리하기 위하여 급속여과지 별로 각각의 역세척 배수변을 2개씩 설치하고 이에 따른 관로를 별개로 설치하며 1개의 배수면은 급속 여과지의 지(地내 배수변에 다른 1개는 역세척수 배수변으로 분리시켜 시설할 수는 있으나, 이들 설비를 모두 구비하기 위해서는 막대한 시설비가 들게되고 또, 기존의 시설을 개량하는데는 거의 불가능한 실정이다.In order to separate the low turbidity water and the high turbidity water, two backwash drains are installed for each of the rapid filter papers, and the pipelines are installed separately according to the rapid filter paper. The other one can be separated by the backwash water drainage side, but it is very expensive to install all of these facilities, and it is almost impossible to improve the existing facilities.

이와 같은 점을 보완하기 위하여 급속여과지의 역세척을 위한 콘트롤 시스템을 설치하고 역세척 배출수가 자동적으로 콘트롤 될수 있도록 2가지의 시스템을 콤바인드 한 것이 본 고안의 특징이다.In order to make up for the above, it is a feature of the present invention to install a control system for backwashing rapid filter paper and combine the two systems so that the backwash discharged water can be controlled automatically.

본 고안의 가장 큰 목적은 여과지의 역세척 시스템에 따라 약간의 미차는 있으나, 역세척으로 인한 손실수량 중 약정도의 손실수량을 직접 회수하므로서 상수도 생산과정의 손실 수량을 최소로 하고, 배출수 재처리 설비의 용량도 이에 비례하여 감소시킴으로서 시설 투자비의 감소와 에너지의 절약을 극대화 하는 데 있다.The main purpose of the present invention is a slight difference depending on the backwashing system of the filter paper. It is to maximize the reduction of facility investment cost and energy savings by minimizing the loss quantity of water production process by directly recovering the amount of loss quantity and reducing the capacity of effluent reprocessing facility in proportion.

이상과 같은 본 고안을 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.When described in detail based on the accompanying drawings of the present invention as follows.

제1도는 일반적인 상수도 생산처리 공정에 급속여과지의 역세척 배출수를 재회수 및 처리하는 과정을 표시한 계통도로 취수장(1)에서 원수를 취수하고 이를 탁수정(2)를 거쳐 흔화지(3), 약품투입부(4), 응집지(5), 약품 침전지(6)로 보내고 침전된 원수를 급속여과지(7)에서 여과하면서 정수지(8)로 보내며 이에 염소주입부(9)에 염소를 주입시켜 송수펌프실(10)의 송출작동으로 상수를 생산하는 과정에 있어서, 급속여과지(7)에서 역세척 배출되는 저탁도수는 제1회수도(11)로 회수하여 농축설비(13)를 거치지 않고 직접 착수정(2)으로 환수시켜 상수도 원수로 사용케하며 고탁도수는 제2회수조(12)로 회수하여 이를 농축설비(13)에서 상등수만 환수하도록 한다.FIG. 1 is a schematic diagram showing the process of re-recovering and treating the backwash effluent of the rapid filter paper in the general waterworks production process. It is sent to the chemical injection section (4), flocculation paper (5), chemical precipitation paper (6) and the precipitated raw water is sent to the purified water (8) while filtering in the rapid filter paper (7) and chlorine is injected into the chlorine injection section (9) In the process of producing the constant water by the operation of the water supply pump chamber 10, the low turbidity water discharged backwashed in the quick filter (7) is recovered to the first recovery (11) directly without going through the concentration facility (13) The water is returned to the intake well (2) to be used as raw water and high turbidity water is recovered to the second recovery tank 12 to recover only the supernatant from the concentration facility 13.

제2도는 물, 공기에 의한 역세척 방식을 나타내는 것으로 양측벽(14)(15)으로 구획된 단위여과지(7)내부의 여과사층(16)상, 하부에는 트라우(trough)(17)와 압력실(18)이 각각 설치되고 중앙배수통로(19)의 일측에는 배수변(20)이 구비된 역세척수 배수기(22)가 형성되며, 그 타측 격벽(14)의 외측에는 압력실(18)과 연통되는 유통관(23)을 설치하고 유통관(23)에는 정수 본거에 연결되는 정수유출관과 역세척수 공급관(24)을 각각 설치하며, 역세척수 배수기(22)에서 배수통로(29)를 거쳐 저탁도수를 제1회수조(11)로 유입되고 고탁도수는 제2회수조(12)로 유입되도록 급속여과지(7)의 역세척 조작과 회조수 유입변의 조작을 콤바인드 콘트롤 하므로서 자동으로 역세척에 의해 배출되는 배출수의 저탁도수와 고탁도수를 분리 회수할수 있다.FIG. 2 shows the backwashing method by water and air, and on the filter sand layer 16 inside the unit filter paper 7 divided into both side walls 14 and 15, the trough 17 and the lower part are shown. Each of the pressure chambers 18 is installed and one side of the central drain passage 19 is provided with a backwash water drain 22 having a drainage side 20, and a pressure chamber 18 outside the other partition 14. A distribution pipe 23 is installed in communication with each other, and a distribution pipe 23 is installed with a purified water outlet pipe and a backwash water supply pipe 24 connected to the purified water main, respectively, and is passed through a drain passage 29 from the backwash water drain 22. The turbid water is introduced into the first recovery tank 11 and the high turbidity water is automatically reversed by combining the backwashing operation of the rapid filter paper 7 and the operation of the freshwater inflow valve so that the turbidity water is introduced into the second recovery tank 12. The low turbidity water and the high turbidity water of the discharged water discharged by washing can be separated and recovered.

급속여과지(7)의 역세척공정(물에 의한 역세척시)을 보면, 원수유입변(21)과 정수변(25)을 닫고, 배수변(20을 열어 여과지내의 최대수위(27)에서 역세척수의(26)까지 물이 배출되면(이때의 배출수는 저탁도수(침전수)임)역세척변(28)을 연다.In the backwashing process of the quick filtration paper 7 (when backwashing with water), the raw water inlet side 21 and the purified water side 25 are closed, and the drainage side 20 is opened to reverse the water at the maximum water level 27 in the filter paper. When the water is discharged to the wash water 26 (the discharge water at this time is a low turbidity water (precipitated water)), the back washing side 28 is opened.

이때 역세척 펌프에 의하여 직송으로 역세철물이 공급되거나 역세척 수조에서 공급된다.At this time, the backwashing iron is directly supplied by the backwash pump or is supplied from the backwash tank.

역세척이 완료되면 역세척변(28)과 배수변(20)을 닫고 원수유입변(21)을 열며 정수변(25)을 점진적으로 연다.When backwashing is completed, the backwashing side 28 and the drainage side 20 are closed, and the raw water inlet side 21 is opened and the integer side 25 is gradually opened.

이상의 공정이 여과지 역세척의 1주기이며 초기의 배출수는 저탁도수이고, 후기의 배출수는 고탁도수이다.The above process is one cycle of filter paper backwashing, the initial discharge water is low turbidity water, and the late discharge water is high turbidity water.

제1, 제2회수조(11)(12)의 유입측에 설치된 유입변(30)(31)은 항상 상호역작용으로 연동하며 유입변(30)이 열리면 유입변(31)이 닫히고 유입변(30)이 닫히면 유입변(31)이 열리게 된다.The inlet sides 30 and 31 installed on the inlet side of the first and second recovery tanks 11 and 12 are always in inverse interaction, and when the inlet side 30 is opened, the inlet side 31 is closed and the inlet side ( When the inlet 30 is closed, the inlet side 31 is opened.

또, 역세척시 배수변(20)을 열면, 조작반(32)으로 신호(33)를 보내주어 회수조의 융입변(30)이 열리게하고 유입변(31)은 닫히게 하므로서 처음 배출되는 저탁도수는 제1회수조(11)로 유입되게 된다.In addition, when the drain side 20 is opened during backwashing, the signal 33 is sent to the operation panel 32 to open the fusion side 30 of the recovery tank and the inlet side 31 to close, so that the low turbidity water discharged first is It is introduced into the first recovery tank (11).

또한, 급속여과지(7)의 수위가 역세척 수위까지 오고 역세척을 위하여 역세척변(28)을 열면 조작반(32)으로 신호(33)가 보내지므로 회수조의 유입변(30)이 닫히고 유입변(31)은 열려 고탁도수가 제2회수조(12)로 유입된다.In addition, the water level of the rapid filter paper 7 reaches the backwashing level and when the backwashing valve 28 is opened for backwashing, a signal 33 is sent to the operation panel 32 so that the inlet side 30 of the recovery tank is closed and the inlet side is closed. 31 is opened and the high turbidity water flows into the second recovery tank 12.

이때 배수통로(29)의 연장거리 및 구배에 따라 물의 도착시간이 다르므로 조작반(32)에서 현장여건에 맞추어 시간을 정확하게 조절한다.At this time, since the arrival time of the water varies depending on the extension distance and the gradient of the drain passage 29, the control panel 32 accurately adjusts the time according to the site conditions.

이와 같이 여과지의 조작과 역세척 회수조의 유입변 조작을 콤바인드 콘트롤 하므로서 급속여과지의 역세척 배축수를 고탁도수와 저탁도수로 자동분리, 회수하게 되고, 깨끗한 저탁도수는 직접회수하여 상수용으로 재사용하며, 고탁도수만을 재처리하므로서 재처리 시설의 용량을 감소할 수 있고 이에 따른 시설비와 유지관리비를 절감할 수 있게된다.As a result of the combined control of the filter paper operation and the inflow valve operation of the backwash recovery tank, the backwashing backwash water of the rapid filter paper is automatically separated and recovered into high turbidity water and low turbidity water, and the clean low turbidity water is directly recovered and recovered. By reusing it as an accommodation, and reprocessing only the high turbidity water, it is possible to reduce the capacity of the reprocessing facility, thereby reducing the facility cost and maintenance costs.

상기의 실시 예는 물에 의한 역세척방식을 나타낸 것이며, 역세척을 공기와 물로 겸용하여 사용하더라도 동일한 효과를 얻을 수 있다.The above embodiment shows the back washing method by water, and the same effect can be obtained even when the back washing is used as air and water.

이상과 같은 본 고안은 콤바인드 콘트롤에 의해서 역세척 배출되는 배출수를 자동 분리하고 또 각각의 유입변을 상호 연동토록 하므로서 저탁도수와 고탁도수를 간편하게 자동 분리 시킬 수 있으며, 상수도의 생산관리를 보다 효율적으로 할수 있고 특히 재처리 시설을 종래에 비하여 월등히 경제적으로 할 수 있는 점 등의 특징을 지닌 것이다.The present invention as described above can automatically separate the low turbidity water and the high turbidity water by automatically separating the discharge water discharged by backwashing by the combined control and interlocking the respective inflow valves. It can be more efficient, and in particular, the reprocessing facilities can be significantly more economical than the conventional features.
