Abstract

The present invention relates to a water treatment apparatus that has been made to solve the problem described above, the water treatment apparatus, according to the present invention, comprising: an adsorption reaction tank (110) which has an inlet part (111) provided thereto through which polluted water is introduced; a spray device (200) which sprays magnetite (Fe3O4) powder into the adsorption reaction tank (110) in order to adsorb phosphorus contained in the polluted water; a recovery tank (120) which has an outlet part (121) provided thereto, and which is connected to an end part of the adsorption reaction tank (110) so as to enable the polluted water containing magnetite (Fe3O4) to flow therein by passing through the adsorption reaction tank (110); and a washing tank (140) which removes the phosphorus from the magnetite (Fe3O4) recovered in the recovery tank (120) by using washing water. In this case, the water treatment apparatus, according to the present invention, uses, among iron oxides (Fe2O3, Fe3O4, FeO) which are by-products generated in steelmaking, magnetite (Fe3O4) exhibiting excellent phosphorus or heavy metal adsorption as an adsorbent, and thus the by-products may be recycled. Particularly, magnetite exhibits a strong magnetic force, and has excellent phosphorus adsorption capacity by having a monodentate and a bidentate formed with a phosphate ion on the particle surface thereof (see figure 1), and thus may effectively remove phosphorus from polluted water. The present invention is a water treatment apparatus whereby polluted water mixed with magnetite (Fe3O4) powder in the adsorption reaction tank (110) is introduced into the recovery tank (120) in which magnetite (Fe3O4) having phosphorus from the polluted water attached to the surface thereof is recovered, and the phosphorus-removed polluted water is discharged, and thus the present invention enables a shorter water treatment time and a higher phosphorus removal efficiency compared to conventionally-used phosphorus removal-type water treatment apparatuses.

Description

마그네타이트를 이용한 수처리장치 및 이를 이용한 수처리방법Water treatment device using magnetite and water treatment method using the same
본 발명은 수처리 장치에 관한 것으로서, 보다 상세하게는 마그네타이트(Fe3O4)를 이용한 수처리장치 및 이를 이용한 수처리방법에 관한 것이다.The present invention relates to a water treatment apparatus, and more particularly, to a water treatment apparatus using magnetite (Fe 3 O 4 ) and a water treatment method using the same.
인은 부영양화의 주원인으로서, 호수나 강 또는 바다에 인이 과량으로 유입되면 미생물이 증식되고, 이로 인해 용존산소가 급격히 고갈되어 수중생물이 폐사하고, 생태계가 파괴된다.Phosphorus is the main cause of eutrophication. When phosphorus is excessively introduced into lakes, rivers or seas, microorganisms multiply, resulting in the rapid depletion of dissolved oxygen, which kills aquatic organisms and destroys ecosystems.
지금까지의 수처리 장치는 이러한 인을 제거하기 위해, 인을 포함하고 있는 오염수를 생물학적인 방법과 물리화학적인 방법으로 제거하는 방법을 사용하고 있다.Conventional water treatment apparatuses use a method of removing contaminated water containing phosphorus by biological and physicochemical methods to remove such phosphorus.
그러나 생물학적인 방법은 인의 제거 과정에 많은 시간이 소요되고, 대형 체류 시설 및 저류시설을 갖추어야 하는 문제가 있다.However, biological methods require a long time for the removal of phosphorus and have a large residence and storage facilities.
응집침전법을 이용하여 인을 제거하는 물리적인 방법은 생물학적인 방법보다 비교적 인 제거공정이 짧은 시간에 이루어지는 장점이 있지만 통상적인 응집제로 사용되는 황산반토(Al2(SO4)3)의 인 제거 효율이 높지 않고, 응집과정에서 많은 양의 슬러지가 발생하는 문제점이 있다.Although the physical method of removing phosphorus using the coagulation sedimentation method has the advantage that the phosphorus removal process is relatively shorter than the biological method, the phosphorus removal efficiency of alumina sulfate (Al2 (SO4) 3) used as a conventional flocculant is not good. Not high, there is a problem that a large amount of sludge occurs in the flocculation process.
인 제거효과를 향상시키기 위해 황산반토(Al2(SO4)3) 대신 제올라이트를 사용하기도 하지만, 제올라이트는 알칼리도를 높이는 데 있어서 약품소모량이 많은 문제점이 있다.Although zeolite may be used instead of alumina sulfate (Al 2 (SO 4) 3) to improve the phosphorus removing effect, zeolite has a problem in that the amount of chemical consumption is high in increasing alkalinity.

또한, 본 발명의 수처리장치는 별도의 약품을 첨가하지 않고 오염수의 인을 제거함과 아울러, 인 흡착제로써 반 영구적인 마그네타이트(Fe3O4) 사용하여 수처리의 운영비를 절감할 수 있다.In addition, the water treatment apparatus of the present invention can remove the phosphorus in the contaminated water without adding a separate chemical, and can also reduce the operating cost of the water treatment by using a semi-permanent magnetite (Fe 3 O 4 ) as a phosphorus adsorbent.

이하, 첨부도면을 참조하여 본 발명의 일 실시 예에 따른 마그네타이트(Fe3O4)를 이용한 수처리장치 및 이를 이용한 수처리방법에 관하여 상세히 설명한다.Hereinafter, a water treatment apparatus using magnetite (Fe 3 O 4 ) and a water treatment method using the same will be described in detail with reference to the accompanying drawings.
본 발명은 상기와 같은 문제점을 해결하기 위하여 도출된 것으로서, 본 발명의 수처리장치는 오염수가 유입되는 유입부(111)가 형성된 흡착반응조(110); 오염수에 포함된 인을 흡착하기 위해 흡착반응조(110)에 마그네타이트(Fe3O4) 분말을 살포하는 살포장치(200); 유출부(121)가 형성됨과 아울러, 흡착반응조(110)를 통과하여 마그네타이트(Fe3O4)를 포함한 오염수가 유입되도록 흡착반응조(110)의 종점부에 연결된 회수조(120); 세척수를 이용하여 회수조(120)에서 회수된 마그네타이트(Fe3O4)에서 인을 제거하는 세척조(140);를 포함한다.The present invention is derived to solve the above problems, the water treatment device of the present invention is the adsorption reaction tank 110 is formed with an inlet 111 is introduced contaminated water; A sprinkling apparatus 200 for spraying magnetite (Fe 3 O 4 ) powder in the adsorption reaction tank 110 to adsorb phosphorus contained in the contaminated water; An outlet 121 and a recovery tank 120 connected to an end portion of the adsorption reaction tank 110 such that contaminated water including magnetite (Fe 3 O 4 ) flows through the adsorption reaction tank 110; It includes; a washing tank 140 for removing phosphorus from the magnetite (Fe 3 O 4 ) recovered from the recovery tank 120 using the washing water.
이 경우, 본 발명의 수처리 장치는 제철 공정에서 발생하는 부산물인 산화철(Fe2O3 , Fe3O4, FeO) 중 인 또는 중금속 흡착이 뛰어난 마그네타이트(Fe3O4)를 흡착제로 사용하기 때문에 부산물을 재활용할 수 있다.In this case, since the water treatment apparatus of the present invention uses a magnetite (Fe 3 O 4 ) excellent in the adsorption of phosphorus or heavy metals in the iron oxides (Fe 2 O 3 , Fe 3 O 4 , FeO) by-products generated in the steelmaking process as an adsorbent. By-products can be recycled.
특히, 마그네타이트는 자기력이 강하고, 입자 표면에 phosphate 이온과의 mono-dentate, bi-dentate가 형성되어 있어 인 흡착성능이 우수하기 때문에(도 1 참고) 오염수의 인을 효과적으로 제거할 수 있다.In particular, magnetite has a strong magnetic force, and mono-dentate and bi-dentate with phosphate ions are formed on the surface of the particles, so that the phosphorous adsorption performance is excellent (see FIG. 1), so that phosphorus in contaminated water can be effectively removed.
본 발명은 흡착반응조(110)에서 마그네타이트(Fe3O4) 분말과 교반된 오염수를 회수조(120)로 유입시켜, 오염수의 인이 표면에 부착된 마그네타이트(Fe3O4)는 회수하고, 인이 제거된 오염수는 유출시키는 수처리장치로서, 기존에 사용되는 인 제거 방식의 수처리장치보다 수처리시간이 짧고. 인 제거 효율이 높다.The present invention is the magnetite in the adsorption tank (110) (Fe 3 O 4 ) powder and the by introducing a number of stirring contaminated with collection tank (120), attached to the surface of the polluted water magnetite (Fe 3 O 4) is recovered In addition, the contaminated water from which phosphorus has been removed is a water treatment device for outflow, and the water treatment time is shorter than that of a conventional phosphorus removal method. Phosphorus removal efficiency is high.
또한, 본 발명의 수처리장치는 대형 수처리 시설을 필요로 하지 않기 때문에 수처리 시설의 제작단가를 절감할 수 있다.In addition, since the water treatment apparatus of the present invention does not require a large water treatment plant, the manufacturing cost of the water treatment plant can be reduced.
뿐만아니라 본원발명의 수처리 장치는 수처리 이후에 슬러지가 발생하지 않고, 환경적으로 유해한 부산물을 발생하지 않기 때문에 환경 친화력이 우수하다.In addition, the water treatment device of the present invention is excellent in environmental friendliness since sludge does not occur after the water treatment and environmentally harmful by-products are not generated.
세척수는 수산화나트륨(NaOH) 용액인 것이 바람직하다. Preferably, the wash water is a sodium hydroxide (NaOH) solution.
이 경우, 마그네타이트(Fe3O4)는 양쪽성(amphoteric) 성질을 갖기 때문에 OH-에 의해 인의 탈착이 용이해 진다.In this case, since magnetite (Fe 3 O 4 ) has an amphoteric property, phosphorus desorption is facilitated by OH − .
따라서 표면에 인이 흡착된 마그네타이트(Fe3O4) 분말이 수산화나트륨(NaOH) 용액에 잠기면 즉시 인이 탈락한다.Therefore, when the magnetite (Fe 3 O 4 ) powder having phosphorus adsorbed on the surface is immersed in sodium hydroxide (NaOH) solution, phosphorus is immediately eliminated.
회수조(120)는 오염수의 인을 표면에 흡착한 마그네타이트(Fe3O4)를 회수하기 위한 자력회수장치(130)가 설치된 것이 바람직하다.The recovery tank 120 is preferably provided with a magnetic recovery device 130 for recovering the magnetite (Fe 3 O 4 ) that is adsorbed phosphorus of the contaminated water on the surface.
자력회수장치(130)는 마그네타이트(Fe3O4)의 자기력을 이용하여 마그네타이트(Fe3O4)를 흡착하는 장치이다.Self-recovering device 130 is a device for adsorbing the magnetite (Fe 3 O 4) using a magnetic force of the magnetite (Fe 3 O 4).
자력회수장치(130)는 모터(131); 모터(131)에 결합되어 회전구동 하는 회전축(132); 상호 간격을 두고, 회전축(132)에 결합된 복수의 자력판(133); 자력판(133)의 전면부 또는 후면부 중 적어도 어느 한 면에 밀착되도록 설치되어, 자력판(133)의 회전구동시 자력판(133)에 흡착된 마그네타이트(Fe3O4)가 자동 탈락하도록 회전축(132)의 상측 영역에 형성된 분리부(134); 분리부(134)에 의해 탈락된 마그네타이트(Fe3O4)를 모아서 제2이송부(136)로 이송시키기 위해 분리부(134)의 하측에 설치된 제1이송부(135);를 포함하고, 제2이송부(136)는 세척조(140)와 연결되어 마그네타이트(Fe3O4)를 세척조(140)로 이송시키는 것이 바람직하다. Magnetic recovery device 130 is a motor 131; A rotating shaft 132 coupled to the motor 131 to rotate; A plurality of magnetic plates 133 coupled to the rotation shaft 132 at intervals from each other; The rotating shaft is installed to be in close contact with at least one surface of the front or rear portion of the magnetic plate 133, so that the magnetite (Fe 3 O 4 ) adsorbed to the magnetic plate 133 during the rotation of the magnetic plate 133 automatically drop off A separator 134 formed in an upper region of the 132; And a first transfer part 135 installed below the separation part 134 to collect and remove the magnetite (Fe 3 O 4 ) dropped by the separation part 134 to the second transfer part 136. The transfer unit 136 may be connected to the washing tank 140 to transfer the magnetite (Fe 3 O 4 ) to the washing tank 140.
이 경우, 자력회수장치(130)는 오염수의 흐름 방향으로 자력판(133)의 단면이 놓이도록 설치된다.(도 2 참고)In this case, the magnetic recovery device 130 is installed so that the cross section of the magnetic plate 133 is placed in the flow direction of the contaminated water (see Fig. 2).
위 자력판(133)의 설치 구조로 인해, 회수조(120)로 유입된 오염수는 자력판(133)의 단면에 부딪히게 되고, 마그네타이트(Fe3O4)가 자력판(133)에 부착된다.Due to the installation structure of the magnetic plate 133, the contaminated water introduced into the recovery tank 120 hits the end face of the magnetic plate 133, the magnetite (Fe 3 O 4 ) is attached to the magnetic plate 133 do.
부착된 마그네타이트(Fe3O4)는 자력판(133)의 회전만으로 세척조(140)로 이송된다. The attached magnetite (Fe 3 O 4 ) is transferred to the washing tank 140 only by the rotation of the magnetic plate 133.
따라서 마그네타이트(Fe3O4)의 회수율이 높다.Therefore, the recovery rate of magnetite (Fe 3 O 4 ) is high.
제1이송부(135)는 제2이송부(136)를 향하여 하향 경사지도록 설치되고, 제2이송부(136)는 세척조(140)를 향하여 하향 경사지도록 설치된 것이 바람직하다. The first transfer part 135 is installed to be inclined downward toward the second transfer part 136, and the second transfer part 136 is preferably installed to be inclined downward toward the washing tank 140.
이 경우, 제1이송부(135)와 제2이송부(136)가 경사를 갖도록 설치되기 때문에 마그네타이트(Fe3O4)는 중력을 따라 자동으로 세척조(140)로 이송된다.In this case, since the first transfer part 135 and the second transfer part 136 are installed to have an inclination, the magnetite Fe 3 O 4 is automatically transferred to the washing tank 140 along the gravity.
흡착반응조(110)는 상하방향으로 지그재그 유로를 갖도록 복수의 격벽(112)이 설치되어 분할된 것이 바람직하다. The adsorption reaction tank 110 is preferably divided into a plurality of partitions 112 are installed to have a zigzag flow path in the vertical direction.
이 경우, 흡착반응조(110)을 분리하여 마그네타이트(Fe3O4)의 인 흡착 시간을 늘리고, 오염수와 마그네타이트(Fe3O4)의 교반을 극대화 할 수 있다.In this case, it is possible to separate the suction tank 110 to increase the absorption time of the magnetite (Fe 3 O 4), to maximize agitation of the contaminated water with magnetite (Fe 3 O 4).
세척조(140)에서 세척이 완료된 마그네타이트(Fe3O4)는 이송관(P1)을 통해 살포장치(200)로 이동되어 재사용 되는 것이 바람직하다.The magnetite (Fe 3 O 4 ), the washing is completed in the washing tank 140 is preferably moved to the spraying apparatus 200 through the transfer pipe (P1) and reused.
이 경우, 세척수에 의해 세척이 완료된 마그네타이트(Fe3O4)를 살포장치로 이동시켜 재사용 할 수 있다.In this case, the magnetite (Fe 3 O 4 ), which has been washed by the washing water, may be moved to a spreading device and reused.
세척조(140)의 세척수는 일정 농도 이상의 인이 축적되면 농축조(150)로 이송되고, 세척수는 농축조(150)에서 인 농도가 조절되어 농업용 비료로 개량되는 것이 바람직하다. The washing water of the washing tank 140 is transferred to the concentration tank 150 when phosphorus is accumulated at a predetermined concentration or higher, and the washing water is preferably improved to agricultural fertilizer by adjusting the phosphorus concentration in the concentration tank 150.
이 경우, 인 농도가 높은 세척수는 농업용 비료로 재생산할 수 있기 때문에 수처리 이후의 부산물을 재활용 할 수 있다.In this case, the washing water having a high phosphorus concentration can be reproduced as agricultural fertilizer, so that the by-products after the water treatment can be recycled.
본 발명의 일 실시 예에 따른 수처리장치를 이용한 수처리방법은 살포장치(200)를 이용하여 흡착반응조(110)로 유입된 오염수에 마그네타이트(Fe3O4) 분말을 살포하는 마그네타이트 살포단계; 회수조(120)에 유입된 오염수에서 마그네타이트(Fe3O4) 분말을 회수하는 마그네타이트 회수단계; 회수조(120)에서 회수된 마그네타이트(Fe3O4) 분말을 세척조(140)로 이송하고, 세척하는 마그네타이트세척단계;를 포함한다.Water treatment method using a water treatment device according to an embodiment of the present invention is a magnetite spraying step of spraying the magnetite (Fe 3 O 4 ) powder to the contaminated water introduced into the adsorption reaction tank 110 using the spraying device (200); A magnetite recovery step of recovering the magnetite (Fe 3 O 4 ) powder from the contaminated water introduced into the recovery tank 120; And a magnetite washing step of transferring the magnetite (Fe 3 O 4 ) powder recovered from the recovery tank 120 to the washing tank 140 and washing it.
마그네타이트 살포단계, 마그네타이트 회수단계, 마그네타이트세척단계는 수처리장치에서 동시에 이루어지는 것이 바람직하다. The magnetite spreading step, the magnetite recovering step, and the magnetite washing step are preferably performed simultaneously in the water treatment apparatus.
이 경우, 마그네타이트 살포단계, 마그네타이트 회수단계, 마그네타이트세척단계가 모두 중단되지 않고 진행될 수 있기 때문에 작업효율이 우수하고, 수처리 공정의 시간을 단축할 수 있다.In this case, since the magnetite spreading step, the magnetite recovery step, the magnetite washing step can all proceed without interruption, the work efficiency is excellent and the time of the water treatment process can be shortened.
본 발명의 또 다른 실시 예에 따른 수처리장치를 이용한 수처리방법은 살포장치(200)를 이용하여 흡착반응조(110)로 유입된 오염수에 마그네타이트(Fe3O4) 분말을 살포하는 마그네타이트 살포단계; 회수조(120)에 유입된 오염수에서 마그네타이트(Fe3O4) 분말을 회수하는 마그네타이트 회수단계; 회수조(120)에서 회수된 마그네타이트(Fe3O4) 분말을 세척조(140)로 이송하고, 세척하는 마그네타이트세척단계; 세척수를 농업용 비료로 사용하기 위해 농축조(150)로 이송하는 농축조이송단계; 농축조(150)로 이송된 세척수에 인을 추가하여 세척수를 농업용 비료로 개량하는 개량단계;를 포함한다.Water treatment method using a water treatment device according to another embodiment of the present invention is a magnetite spraying step of spraying the magnetite (Fe 3 O 4 ) powder in the contaminated water introduced into the adsorption reaction tank 110 using the spraying device (200); A magnetite recovery step of recovering the magnetite (Fe 3 O 4 ) powder from the contaminated water introduced into the recovery tank 120; A magnetite washing step of transferring the magnetite (Fe 3 O 4 ) powder recovered from the recovery tank 120 to the washing tank 140 and washing it; Concentration tank transfer step of transferring the washing water to the concentration tank 150 for use as agricultural fertilizer; Includes an improved step of improving the washing water to agricultural fertilizer by adding phosphorus to the washing water transferred to the concentration tank 150.
이 경우, 수처리 이후에 발생하는 세척수를 농업용 비료로 개량할 수 있기 때문에 수처리 이후의 부산물을 재활용 할 수 있다.In this case, since the wash water generated after the water treatment can be improved to agricultural fertilizer, the by-products after the water treatment can be recycled.
