The configuration of the wastewater treatment system 100 is as shown in FIG. As described above, the reactor 110, the electrode 120, the pretreatment unit 140, and the controller 150 are included.

반응조(110)는 폐수가 유입되어 전기분해 된 후 배출되는 곳이다. 이러한 반응조(110)의 일측에는 폐수가 유입되는 입구(112)와, 타측에는 여과된 폐수가 배출되는 출구(114)가 형성된다.The reactor 110 is a place where wastewater is introduced and discharged after electrolysis. One side of the reactor 110 is formed with an inlet 112 through which waste water is introduced, and an outlet 114 through which filtered waste water is discharged.

여기에서, 입구(112)에는 유입관(116)이 연결되어 반응조(110)의 천정측으로 연장된다. 그리고 출구(114)에는 유출관(118)이 연결되어 반응조(110)의 바닥측으로 연장된다.Here, the inlet pipe 116 is connected to the inlet 112 and extends to the ceiling side of the reactor 110. And outlet 114 is connected to the outlet pipe 118 extends to the bottom side of the reaction tank (110).

이와 같이 형성된 반응조(110)의 하부측에는 도 2에서 보는 바와 같이 횡방향으로 여과용 스트레나(130)가 설치되고, 이 스트레나(130)의 상부측에는 전해질(127)이 충진된다. 여기에서 전해질로는 흑연과 활성탄이 사용된다.As shown in FIG. 2, the lower side of the reaction tank 110 formed as described above is provided with a filtering strainer 130 in the horizontal direction, and the upper side of the strainer 130 is filled with an electrolyte 127. Here, graphite and activated carbon are used as electrolytes.

그리고 전해질(127)이 충진된 반응조(110)의 측면에는 다수의 전극봉(120)이 설치된다.In addition, a plurality of electrode rods 120 are installed on the side surface of the reaction tank 110 filled with the electrolyte 127.

도 3은 도 2에 도시된 전극봉의 형상을 나타낸 도면이며, 그리고 도 4는 도 2에 도시된 전극봉들의 배열을 나타낸 배치도이다.3 is a view showing the shape of the electrode shown in Figure 2, and Figure 4 is a layout view showing the arrangement of the electrode shown in FIG.

전극봉(120)은 로링가공하여 볼트체결 방식으로 분리 및 교체를 간편하게 할 수 있도록 하고 전극봉(120)에는 흑연과 활성탄이 덮이도록 설치한다.The electrode rod 120 is roringed to facilitate separation and replacement in a bolted manner, and the electrode rod 120 is installed to cover graphite and activated carbon.

전극봉(120)에 대해 좀더 자세하게 살펴보면, 도 3에서 보는 바와 같이 전극봉(120)은 단자부(121), 절연부(122), 전극부(123)로 구성된다. 단자부(121)는 전원을 연결하는 부분이며 절연부(122)는 반응조(110)에 전극봉(120)을 설치할 때 반응조(110)와 전극봉(120)간의 절연상태를 유지하도록 절연물질로 가공되었으며 분리 및 교체를 간편하게 할 수 있도록 나사의 형태로 가공하였다. 전극부(123)는 철(Fe) 또는 알루미늄(Al) 등으로 가공하였으며 원형봉 형태이다.Looking at the electrode 120 in more detail, as shown in Figure 3, the electrode 120 is composed of a terminal portion 121, the insulating portion 122, the electrode portion 123. The terminal part 121 is a part for connecting a power source, and the insulating part 122 is processed with an insulating material to maintain an insulating state between the reaction tank 110 and the electrode 120 when installing the electrode 120 in the reaction tank 110. And it was processed in the form of a screw for easy replacement. The electrode part 123 is processed with iron (Fe) or aluminum (Al), and has a round rod shape.

이러한 전극봉(120)의 배열은 도 4에서 보는 바와 같이 하나는 양극(+) 다른 하나는 음극(-)으로 사용하며, 수직 수평으로 일정간격(약 100mm)으로 이격하여 단계적으로 설치한다. 전극봉(120)은 양극과 음극을 같은 종류의 금속을 사용하고 음극봉은 용출되지 않기 때문에 장기간 사용시 음극을 양극으로 전환 사용할 수 있도록 한다.As shown in FIG. 4, the arrangement of the electrode 120 is one positive electrode (+) and the other negative electrode (−), and is vertically spaced at a predetermined interval (about 100 mm) to be installed step by step. The electrode 120 uses the same type of metal as the positive electrode and the negative electrode, and the negative electrode does not elute so that the cathode can be used as a positive electrode for a long time.

한편, 전처리수단(140)은 반응조(110)의 입구(112)로 폐수가 들어오기전에 폐수의 유량이나 조건 등을 체크하여 최적의 반응조건을 제공하기 위한 수단으로, 유량계(141)와, 라인믹서(142)와, 약품정량펌프(145)를 포함한다.On the other hand, the pretreatment means 140 is a means for checking the flow rate or conditions of the wastewater before the wastewater enters the inlet 112 of the reaction tank 110 to provide the optimum reaction conditions, flow meter 141 and the line A mixer 142 and a chemical metering pump 145 are included.

유량계(141)는 폐수의 유량을 체크하여 콘트롤부(150)에서 유량에 따른 적절한 전류를 공급하는데 사용된다.The flow meter 141 is used to check the flow rate of the waste water and supply the appropriate current according to the flow rate in the control unit 150.

라인믹서(142)는 유량계(141)를 통과한 폐수를 약품과 함께 섞어주는 곳으로 약품정량펌프(145)와 유기적으로 작동된다. 이때, 라인믹서(142)의 후방에는 약품과 혼합된 폐수의 pH나 또는 전도도를 체크하기 위한 pH조정조(143)가 더 포함된다. 즉, pH조정조(143)에는 pH센서 또는 전도도센서(144)가 설치되어 이 센서(144)에서 체크된 pH 또는 전도도를 콘트롤부(150)에서 분석하여 약품정량펌프(145)에서 필요조건에 따른 약품을 정량 공급해준다.The line mixer 142 is organically operated with the chemical metering pump 145 where the wastewater that has passed through the flow meter 141 is mixed with the chemical. At this time, the rear of the line mixer 142 further includes a pH adjusting tank 143 for checking the pH or conductivity of the wastewater mixed with the chemicals. That is, the pH adjustment tank 143 is provided with a pH sensor or conductivity sensor 144 to analyze the pH or conductivity checked in the sensor 144 in the control unit 150 according to the requirements in the chemical metering pump 145 Provide a fixed amount of medicine.

끝으로, 콘트롤부(150)는 DC전압전류를 제어하는 파워콘트롤부(151)와 폐수처리시스템(100)을 제어하는 시스템콘트롤부(152)로 구성된다. 파워콘트롤부(151)에서 출력전원은 DC10V ~ 100V까지 제어가 가능하며 전압의 세기에 따라서 전극봉(120)의 전해 용출반응에 의한 처리시간이 조정된다.Finally, the control unit 150 is composed of a power control unit 151 for controlling the DC voltage current and a system control unit 152 for controlling the wastewater treatment system 100. In the power control unit 151, the output power can be controlled from DC 10V to 100V, and the processing time by the electrolytic elution reaction of the electrode 120 is adjusted according to the intensity of the voltage.

하기에는 콘트롤부(150)의 제어에 의해 각부의 요소들이 작동되는 방법 및 처리순서를 간단하게 설명한다.The following briefly describes how the elements of each unit operate under the control of the controller 150 and the processing procedure.

먼저, 콘트롤부(150)에 의한 전처리수단(140)들의 작동을 살펴본다.First, look at the operation of the pre-processing means 140 by the control unit 150.

유량계(141)에서 유량을 체크하면, 콘트롤부(150)에서 유량에 따라 전극봉(120)으로 공급하는 DC전류의 세기를 조정해준다. 즉, 유량이 많으면 전류의 세기를 높이고, 유량이 적으면 전류의 세기를 낮이게 되는 것이다.When the flow rate is checked in the flow meter 141, the control unit 150 adjusts the intensity of the DC current supplied to the electrode 120 according to the flow rate. In other words, if the flow rate is large, the strength of the current is increased, and if the flow rate is small, the strength of the current is decreased.

그리고 라인믹서(142)를 통과한 폐수의 pH나 전도도를 pH조정조(143)에서 체크하여 최적의 조건에 맞도록 약품정량펌프(145)를 조정하여 적당한 약품을 라인믹서(142)로 공급하도록 한다.Then, the pH or conductivity of the wastewater passing through the line mixer 142 is checked by the pH adjusting tank 143 to adjust the chemical metering pump 145 to meet the optimum conditions so that the appropriate chemical is supplied to the line mixer 142. .

다음은 본 발명에 따른 폐수처리시스템(100)의 처리순서를 살펴본다.Next, a treatment sequence of the wastewater treatment system 100 according to the present invention will be described.

전처리수단(140)을 거쳐 입구(112)를 통해 유입된 폐수는 유입관(116)을 통해 반응조(110)의 상측에서 배출된다.Wastewater introduced through the inlet 112 through the pretreatment means 140 is discharged from the upper side of the reaction tank 110 through the inlet pipe 116.

유입관(116)에서 배출되는 폐수는 흑연과 활성탄을 거치면서 전극봉(120)에 의해 전기분해를 일으키고, 스트레나(130)를 거쳐 하측으로 흘러 반응조(110)의 바닥층으로 쌓이게된다.Wastewater discharged from the inlet pipe 116 is electrolyzed by the electrode rod 120 while passing through graphite and activated carbon, and flows downward through the strainer 130 to be accumulated in the bottom layer of the reaction tank 110.

계속해서 폐수가 쌓이면 반응조(110)내의 압력이 점점 높아지면서 여과된 폐수는 유출관(118)을 통해 출구(114)로 배출된다.If the waste water continues to accumulate, the pressure in the reactor 110 is gradually increased, and the filtered waste water is discharged to the outlet 114 through the outlet pipe 118.

한편, 상기와 같은 처리를 반복해서 실시하다보면 폐수가 상부에서 하부로 흐르기 때문에 흑연 및 활성탄이나 스트레나(130)에 많은 이물질들이 적층되게 된다. 이처럼 이물질들이 쌓이게 되면 반응조(110)내의 여과작용에 효율이 떨어지게 된다.On the other hand, if the above treatment is repeatedly performed, many foreign matters are stacked on graphite and activated carbon or strainer 130 because the waste water flows from the top to the bottom. As such foreign matters accumulate, the efficiency of the filtration in the reactor 110 is reduced.

따라서 폐수처리시스템(100)의 효율적인 가동을 위해서는 적층된 이물질들을 제거해 주는 역세수단이 더 필요하게 된다.Therefore, in order to efficiently operate the wastewater treatment system 100, a backwashing means for removing the stacked foreign matters is required.

도 5는 본 발명에 따른 폐수처리시스템에 역세가동을 위한 구성을 추가한 도면이다.5 is a view in addition to the configuration for backwash operation to the wastewater treatment system according to the present invention.

역세수단은 반응조(110)내에 물을 공급하여 공급된 물이 반응조(110)의 바닥면에서부터 상부로 차 오르게 하여 적층된 이물질들이 부유하게 한 후 이 물을 반응조(110)의 상부측에서 배출시키는 수단이다.The backwashing means supplies water in the reaction tank 110 so that the supplied water rises from the bottom surface of the reaction tank 110 to the upper side to make the stacked foreign matters float, and then discharges the water from the upper side of the reaction tank 110. Means.

이러한 역세수단에 필요한 구성으로는 도 5에서 보는 바와 같이 반응조의 타측과 상부측 및 하부측에 형성되는 세 개의 역세관(161,162,163)과, 이들을 제어하 는 다섯 개의 전자밸브(171,172,173,174,175)와, 산기장치(180)가 포함된다.As shown in FIG. 5, three backwash tubes 161, 162, 163 are formed on the other side, the upper side, and the lower side of the reaction tank, five solenoid valves 171, 172, 173, 174, 175 to control them, and an air diffuser. 180 is included.

세 개의 역세관(161,162,163)은 먼저, 제1역세관(161)은 유입관(116)의 중간부분에 연결되어 반응조(110)의 타측으로 관통되고, 다음으로, 제2역세관(162)은 반응조(110)의 상부면상에 형성되며, 끝으로, 제3역세관(163)은 반응조(110)의 하부면상에 형성된다. 그리고 유출관(118)의 중간부분에는 입구(112)와 연결되는 역세유입관(164)이 더 형성된다. 즉, 유입관(116)과 역세유입관(164)은 입구(112)에서 분기되는 구조를 갖는다.Three backwashing pipes (161, 162, 163) are first, the first backwashing pipe (161) is connected to the middle portion of the inlet pipe (116) is penetrated to the other side of the reaction tank 110, and then, the second backwashing pipe (162) It is formed on the upper surface of the reaction tank 110, and finally, the third back washing tube 163 is formed on the lower surface of the reaction tank (110). And the backwash inlet pipe 164 is further formed in the middle portion of the outlet pipe 118 is connected to the inlet (112). That is, the inlet pipe 116 and the backwash inlet pipe 164 has a structure branched from the inlet (112).

다섯 개의 전자밸브(171,172,173,174,175)는 먼저, 제1전자밸브(171)는 유입관(116)에서 제1역세관(161)이 연결되는 전방측에 설치되고, 다음으로, 제2전자밸브(172)는 제1역세관(161)에 설치되고, 다음으로, 제3전자밸브(173)는 역세유입관(164)에 형성되며, 다음으로, 제4전자밸브(174)는 유출관(118)에서 역세유입관(164)이 연결되는 후방측에 설치되며, 마직막으로, 제5전자밸브(175)는 제3역세관(163)에 설치된다. 이와 같이 설치된 전자밸브(171,172,173,174,175)들은 콘트롤부(150)의 제어에 의해 각각이 선택적으로 개폐된다. 바람직하게는 제1전자밸브(171)와 제4전자밸브(174)가 한쌍으로 열고 닫히며, 제2전자밸브(172)와 제3전자밸브(173)가 한쌍으로 열고 닫힌다.Five solenoid valves 171, 172, 173, 174, 175 are firstly installed, and the first solenoid valve 171 is installed at the front side to which the first backwashing tube 161 is connected in the inlet pipe 116, and then, the second solenoid valve 172. Is installed in the first backwashing pipe 161, and then, the third solenoid valve 173 is formed in the backwashing inlet pipe 164, and then, the fourth solenoid valve 174 is in the outlet pipe 118. It is installed on the rear side to which the backwash inlet pipe 164 is connected, and finally, the fifth solenoid valve 175 is installed on the third backwashing pipe 163. The solenoid valves 171, 172, 173, 174, and 175 installed as described above are selectively opened and closed by the control of the controller 150. Preferably, the first solenoid valve 171 and the fourth solenoid valve 174 open and close in pairs, and the second solenoid valve 172 and the third solenoid valve 173 open and close in pairs.

산기장치(180)는 반응조(110)의 바닥면측으로 외부공기를 공급하는 장치로, 반응조(110)외부에 구비되는 콤프레셔(181)와, 콤프레셔(181)에 연결되어 반응조(110)의 바닥면상에 설치되는 산기관(182)을 포함한다.The diffuser device 180 is a device for supplying external air to the bottom surface side of the reaction tank 110, and is connected to the compressor 181 provided outside the reaction tank 110 and the compressor 181 on the bottom surface of the reaction tank 110. It includes a diffuser 182 is installed in.

하기에는 전술한 바와 같이 형성된 역세수단이 구비된 폐수처리시스템(100) 의 작동에 대해 간략하게 살펴본다.Hereinafter, the operation of the wastewater treatment system 100 having the backwashing means formed as described above will be briefly described.

우선, 정상작동시에는 콘트롤부(150)의 지시에 따라 제1전자밸브(171) 및 제4전자밸브(174)가 열리고, 제2전자밸브(172) 및 제3전자밸브(173)가 닫히게 된다.First, in the normal operation, the first solenoid valve 171 and the fourth solenoid valve 174 are opened, and the second solenoid valve 172 and the third solenoid valve 173 are closed according to the instruction of the controller 150. do.

따라서 입구(112)를 통해 유입된 폐수는 유입관(116)과 역세유입관(164)으로 유입되지만 역세유입관(164)의 제3전자밸브(173)가 닫혀있게 되어 제1전자밸브(171)를 통해 유입관(116)으로만 유입된다.Therefore, the wastewater introduced through the inlet 112 flows into the inlet pipe 116 and the backwash inlet pipe 164, but the third solenoid valve 173 of the backwash inlet pipe 164 is closed so that the first solenoid valve 171 is closed. Only through the inlet pipe 116 through.

그리고 유입관(116)으로 유입된 폐수는 다시 제2전자밸브(172)가 닫혀있게 되어 제1역세관(161)으로는 배출되지 않고 반응조(110)의 천정으로 연장된 유입관(116)의 연장부에서 배출된다.In addition, the wastewater introduced into the inlet pipe 116 is again closed by the second solenoid valve 172 and is not discharged to the first backwashing pipe 161 but the inlet pipe 116 extending to the ceiling of the reaction tank 110. Ejected from the extension.

유입관(116)의 연장부에서 배출되는 폐수는 반응조(110)의 상측에서부터 점차 아래로 흐르면서 전극봉(120)에 의해 전기분해되고 또, 스트레나(130)를 거쳐 여과되면서 반응조(110)의 바닥면에 모이게 된다.Waste water discharged from the extension of the inlet pipe 116 is gradually electrolyzed by the electrode 120 while flowing downward from the upper side of the reaction tank 110, and filtered through the strainer 130, the bottom surface of the reaction tank 110 Gathered at

계속해서 여과된 폐수가 쌓이면 폐수는 다시 반응조(110)의 상측으로 차 올라가게 되고 이에 따라 반응조(110)내의 수압이 높아지면서 여과된 폐수는 유출관(118)을 통해 열려져 있는 제4전자밸브(174)를 통과해 출구(114)로 배출된다.If the filtered wastewater continues to accumulate, the wastewater rises to the upper side of the reaction tank 110 again. As a result, the water pressure in the reaction tank 110 increases, and the filtered wastewater is opened through the outlet pipe 118. Passed through outlet 174 to outlet 114.

한편, 필요에 따라 역세가동을 작동시키면, 콘트롤부(150)의 역세지시에 따라 열려져 있던 제1전자밸브(171) 및 제4전자밸브(174)가 닫히고, 반대로 닫혀져 있던 제2전자밸브(172) 및 제3전자밸브(173)가 열리게 된다.On the other hand, when the backwash operation is operated as necessary, the first solenoid valve 171 and the fourth solenoid valve 174 opened according to the backwash instruction of the control unit 150 are closed, and the second solenoid valve 172 which is closed on the contrary is closed. ) And the third solenoid valve 173 are opened.

입구(112)를 통해 역세에 사용될 물이 공급되면 열려져 있는 역세유입관(164)의 제3전자밸브(173)를 통해 반응조(110)의 바닥면으로 물이 배출된다.When water to be used for backwashing is supplied through the inlet 112, water is discharged to the bottom surface of the reaction tank 110 through the third solenoid valve 173 of the open backwashing inlet pipe 164.

바닥면으로 배출되는 물은 반응조(110)의 상층부까지 차올라 스트레나(130)나 흑연 및 활성탄에 적층되어 있던 이물질들을 부유시키게 된다. 이때, 산기장치(180)가 작동되어 산기관(182)으로 외부공기를 유입시키면서 압력을 높여주어 역세효율을 증가시킨다.The water discharged to the bottom surface floats the foreign substances stacked on the strainer 130 or graphite and activated carbon to the upper layer of the reaction tank 110. At this time, the diffuser device 180 is operated to increase the pressure while increasing the pressure while introducing external air into the diffuser 182.

이처럼 반응조(110)의 상부로 차오른 물에 의해 부유물들이 유입관(116)의 연장부를 통해 열려져 있는 제2전자밸브(172)를 거쳐 제1역세관(161)으로 배출된다.In this way, the suspended solids are discharged to the first back washing pipe 161 through the second solenoid valve 172 opened through the extension of the inlet pipe 116 by the water filled to the upper portion of the reaction tank 110.

그리고 역세도중 유입관(116)에 과도한 압력이 걸리게 되면 원활한 역세가 작동되지 않게 되므로 반응조(110)의 상부에 구비된 제2역세관(162)를 통해 보조 역세가 이루어지도록 마련된다.In addition, when excessive pressure is applied to the inlet pipe 116 during the backwashing, since the backwashing is not operated smoothly, the auxiliary backwashing is provided through the second backwashing pipe 162 provided at the upper portion of the reaction tank 110.

끝으로, 역세가 마무리 되면, 반응조(110)내에 유입된 역세에 사용된 물을 반응조(110)의 하부에 설치된 제3역세관(163)의 제5전자밸브(175)가 열리면서 역세에 사용된 물이 배출된다.Finally, when the backwashing is finished, the fifth solenoid valve 175 of the third backwashing pipe 163 installed at the bottom of the reaction tank 110 opens the water used for the backwashing flowed into the reaction tank 110 and is used for backwashing. Water is discharged.

또한, 전극을 탈부착이 간편하도록 제작하여 교체 및 유지보수를 효율적으로 할 수 있다.In addition, the electrode can be easily attached and detached, and replacement and maintenance can be efficiently performed.

또한, 전해질을 흑연과 혼합하여 사용함으로써 전해반응의 효과를 높일 수 있다.In addition, the effect of the electrolytic reaction can be enhanced by using the electrolyte mixed with graphite.
