Abstract:
(EN) 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 upward filtration tank (110) which, in order to remove phosphorus contained in polluted water, is provided with a filtration unit (111) filled with magnetite (Fe3O4) powder which is a by-product of a steel-rolling process; a first flow path (P1) which transfers polluted water to the filtration tank (110); a branching pipe path (150) which downwardly introduces, into the filtration tank (110), washing water for washing phosphorus adsorbed on the surface of the magnetite (Fe3O4) having magnetic force, and which is coupled to the filtration tank (110) in order to discharge the polluted water that has passed through the filtration unit (111), wherein the branching pipe path (150) comprises a coupling part (151) coupling with the filtration tank (110), an outlet part (154) coupled to the coupling part (151) by means of a bent section (152), and an inlet part (155) coupled to a branching section (153) of the outlet part (154); a first adsorption device (160) which is provided to the coupling part (151) in order to recover, using magnetic force, magnetite (Fe3O4) powder that is contained in the polluted water as a result of breaking away from the filtration unit (111); a first adsorption unit (A) which is formed on an inner surface of the coupling part (151) by means of the magnetic force of the first adsorption device (160); a second flow path (P2) which is coupled to the outlet part (154) in order to discharge the polluted water; a third flow path (P3) which is coupled to the inlet part (155) so as to enable washing water to be introduced; a washing water tank (120) which is connected to the third flow path (P3); a fourth flow path (P4) which is connected to the filtration tank (110) so as to discharge the washing water; and a phosphorus discharge tank (130) which is connected to the fourth flow path (P4). 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.
(FR) La présente invention concerne un appareil de traitement des eaux qui a été conçu pour résoudre le problème mentionné ci-dessus, l'appareil de traitement des eaux selon l'invention comprenant : un réservoir de filtration de bas en haut (110) qui, afin d'éliminer le phosphore contenu dans de l'eau polluée, est équipé d'une unité de filtration (111) remplie de magnétite (Fe3O4) sous forme de poudre qui est un sous-produit d'un procédé de laminage d'acier; un premier trajet d'écoulement (P1) qui transfère l'eau polluée vers le réservoir de filtration (110); un trajet de tuyau de ramification (150) qui introduit vers le bas, dans le réservoir de filtration (110), de l'eau de lavage pour laver le phosphore adsorbé sur la surface de la magnétite (Fe3O4) ayant une force magnétique, et qui est couplé au réservoir de filtration (110) afin d'évacuer l'eau polluée qui a traversé l'unité de filtration (111), le trajet de tuyau de ramification (150) comprenant une partie de couplage (151) se couplant avec le réservoir de filtration (110), une partie de sortie (154) couplée à la partie de couplage (151) par l'intermédiaire d'une section courbée (152), et une partie d'entrée (155) couplée à une section de ramification (153) de la partie de sortie (154); un premier dispositif d'adsorption (160) qui est fourni au niveau de la partie de couplage (151) afin de récupérer, en utilisant la force magnétique, la magnétite (Fe3O4) sous forme de poudre qui est contenue dans l'eau polluée suite à sa séparation de l'unité de filtration (111); une première unité d'adsorption (A) qui est formée sur une surface interne de la partie de couplage (151) au moyen de la force magnétique du premier dispositif d'adsorption (160); un deuxième trajet d'écoulement (P2) qui est couplé à la partie de sortie (154) afin d'évacuer l'eau polluée; un troisième trajet d'écoulement (P3) qui est couplé à la partie d'entrée (155) de sorte à permettre l'introduction de l'eau de lavage; un réservoir d'eau de lavage (120) qui est connecté au troisième trajet d'écoulement (P3); un quatrième trajet d'écoulement (P4) qui est connecté au réservoir de filtration (110) de sorte à évacuer l'eau de lavage; et un réservoir d'évacuation de phosphore (130) qui est connecté au quatrième trajet d'écoulement (P4). Dans ce cas, l'appareil de traitement des eaux selon la présente invention utilise, parmi les oxydes de fer (Fe2O3, Fe3O4, FeO) qui sont des sous-produits générés dans l'élaboration de l'acier, de la magnétite (Fe3O4) présentant une excellente capacité d'adsorption de phosphore ou de métaux lourds en tant qu'adsorbant, ce qui fait en sorte que les sous-produits peuvent être recyclés. En particulier, la magnétite présente une force magnétique élevée, et a une excellente capacité d'adsorption du phosphore en ayant un monodentate et un bidentate formés avec un ion phosphate sur sa surface de particule (voir figure 1), et peut ainsi éliminer efficacement le phosphore de l'eau polluée.
(KO) 본 발명은 상기와 같은 문제점을 해결하기 위하여 도출된 것으로서, 본 발명의 수처리장치는 오염수에 포함된 인을 제거하기 위해, 강재 압연공정의 부산물인 마그네타이트(Fe3O4) 분말이 채워진 여과부(111)를 구비한 상향 여과조(110); 여과조(110)로 오염수를 이송하는 제1유로(P1); 자기력을 갖는 마그네타이트(Fe3O4)의 표면에 흡착된 인을 세척하기 위한 세척수를 여과조(110)로 하향 유입시키고, 여과부(111)를 통과한 오염수를 배출시키기 위해 여과조(110)에 결합된 분기관로(150);를 포함하고, 분기관로(150)는 여과조(110)와 결합되는 결합부(151); 절곡부(152)에 의해 결합부(151)에 결합되는 유출부(154); 유출부(154)의 분기부(153)에 결합된 유입부(155);를 구비하며, 여과부(111)에서 이탈되어 오염수에 포함된 마그네타이트(Fe3O4) 분말을 자기력으로 회수하기 위해 결합부(151)에 형성된 제1흡착장치(160); 제1흡착장치(160)의 자기력에 의해 결합부(151) 내측면에 형성된 제1흡착부(A); 오염수를 배출하기 위해 유출부(154)에 결합된 제2유로(P2); 세척수가 유입되도록 유입부(155)에 결합된 제3유로(P3); 제3유로(P3)에 연결된 세척수조(120); 세척수를 유출하도록 상기 여과조(110)에 연결된 제4유로(P4); 제4유로(P4)에 연결된 인배출조(130);를 포함한다. 이 경우, 본 발명의 수처리장치는 제철 공정에서 발생하는 부산물인 산화철(Fe2O3 , Fe3O4, FeO) 중 인 또는 중금속 흡착이 뛰어난 마그네타이트(Fe3O4)를 흡착제로 사용하기 때문에 부산물을 재활용할 수 있다. 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.
