An aluminum salt inlet tube 14 and a sodium hydroxide inlet tube 15 are provided on the treated water inlet tube 11, and a polymer inlet tube 16 is provided on the main body 20 described later for phosphorus removal. The first treatment of the wastewater refers to processes such as sedimentation and aeration, but is not necessarily limited thereto, and the present invention is not necessarily limited thereto, although the present invention requires phosphorus removal.

본 발명에 따르면 본체(20) 내부에 원추통(21), 내통(23), 중간통(25)을 구비하여 1차상향유로(20a), 하향유로(20b), 2차상향유로(20c)의 순서로 하폐수의 교반을 수행하는 구조이다. 본체(20)는 하폐수의 원활한 유동과 교반을 위해 원통형으로 형성함이 적절하다. 본체(20)의 일측 외주면에 처리수유입관(11)이 연결되고 타측 외주면에 방류수유출관(12)과 슬러지배출관(13)이 연결된다. 이외에 알루미늄염투입관(14), 수산화나트륨투입관(15), 폴리머투입관(16)을 구비하여 인을 제거하는 기본 원리는 종래와 동일하게 적용할 수 있다. 본체(20)에서 처리수유입관(11)이 하측에 위치하고 방류수유출관(12)이 상측에 위치하므로 전반적으로 하폐수의 상향식 유동을 유발한다. 상기 원추통(21)의 세부 구성과 작용은 후술하는 설명을 참조한다.According to the present invention, the main cylinder 20 has a conical cylinder 21, an inner cylinder 23, and an intermediate cylinder 25, and includes a primary upward passage 20a, a downward passage 20b, and a secondary upward passage 20c. It is a structure to perform the stirring of the waste water in the order of. The body 20 is suitably formed in a cylindrical shape for smooth flow and agitation of the wastewater. The treatment water inlet pipe 11 is connected to one outer peripheral surface of the main body 20, and the discharge water discharge pipe 12 and the sludge discharge pipe 13 are connected to the other outer peripheral surface thereof. In addition to the aluminum salt inlet tube 14, sodium hydroxide inlet tube 15, the polymer inlet tube 16 is provided with the same basic principle to remove the phosphorus can be applied. In the main body 20, the treated water inlet pipe 11 is located at the lower side and the discharge water outlet pipe 12 is located at the upper side, thereby causing an overall upward flow of the wastewater. Detailed configuration and operation of the cone cylinder 21, see the description below.

이때, 본 발명은 상기 원추통(21)의 상측으로 내통(23)을 구비하여 1차상향유로(20a)를 형성하고, 내통(23)의 외측으로 중간통(25)을 구비하여 하향유로(20b)와 2차상향유로(20c)를 형성한다. 원추통(21)은 상부가 개방된 역삼각형 형태로 본체(20)의 내부에 고정되고, 내통(23)과 중간통(25)은 동심축 상으로 본체(20)의 상면에 고정되어 원추통(21)의 상단까지 연장된다. 이와 같은 방식으로 내통(23)의 내부 공간은 1차상향유로(20a)를 형성하고, 내통(23)과 중간통(25)의 사이 공간은 하향유로(20b)를 형성하고, 내통(23)의 외부 공간은 2차상향유로(20c)를 형성한다. 원추통(21)이 역삼각형 구조로 설치되므로 상측으로 갈수록 하폐수의 유로 단면적이 축소되어 유동 속도가 증대된다. At this time, the present invention is provided with an inner cylinder 23 to the upper side of the conical cylinder 21 to form a primary upward flow path (20a), and having an intermediate cylinder 25 to the outside of the inner cylinder (23) downward flow path ( 20b) and the secondary upward flow path 20c are formed. Conical cylinder 21 is fixed to the inside of the main body 20 in the form of an inverted triangle, the upper portion is open, the inner cylinder 23 and the intermediate cylinder 25 is fixed to the upper surface of the main body 20 concentrically on the conical cylinder It extends to the top of 21. In this manner, the inner space of the inner cylinder 23 forms the primary upward flow path 20a, and the space between the inner cylinder 23 and the intermediate cylinder 25 forms the downward flow path 20b, and the inner cylinder 23. The outer space of the to form a secondary upward flow path (20c). Since the cone cylinder 21 is installed in an inverted triangle structure, the flow cross-sectional area of the wastewater is reduced toward the upper side, thereby increasing the flow rate.

본 발명에 의하면, 상기 본체(20)는 처리수유입관(11)과 라인믹서(10)를 개재하여 연결된다. 라인믹서(10)는 별도의 동력을 부가하지 않아도 처리수유입관(11)으로 유동하는 하폐수의 압력에 의하여 급속한 교반작용을 유발한다. 알루미늄염투입관(14)으로 투입되는 알럼(ALUM)과 반응시 하폐수의 pH가 낮아지므로 수산화나트륨투입관(15)으로 NaOH를 투입하여 pH를 조절한다. 라인믹서(10)를 거쳐 본체(20)에 도달하는 동안 급속교반에서 원심력에 의한 중속교반으로 변동된다.According to the present invention, the main body 20 is connected via the treatment water inlet pipe 11 and the line mixer 10. The line mixer 10 causes a rapid stirring action by the pressure of the sewage water flowing into the treated water inlet pipe 11 without applying additional power. Since the pH of the wastewater is lowered upon reaction with ALUM (ALUM) introduced into the aluminum salt inlet tube 14, NaOH is added to the sodium hydroxide inlet tube 15 to adjust the pH. While reaching the main body 20 via the line mixer 10, it is changed from rapid stirring to medium speed stirring by centrifugal force.

이때, 상기 본체(20)는 원추통(21)의 하측으로 원심혼화유로(22a)를 유도하기 위한 원심혼화조(22)를 형성한다. 원추통(21)은 본체(20)에서 하측으로 위치하고 내통(23)과 중간통(25)은 본체(20)에서 상측으로 위치한다. 도 2처럼 처리수유입관(11)이 원추통(21)의 하측에 형성되는 원심혼화조(22)에 원심력을 유발하도록 편심방향으로 연결된다. 이에 따라, 하폐수는 원심혼화유로(22a), 1차상향유로(20a), 하향유로(20b), 2차상향유로(20c)의 순서로 교반을 수행한다.At this time, the main body 20 forms a centrifugal mixing tank 22 for inducing the centrifugal mixing passage 22a to the lower side of the cone cylinder 21. The cone cylinder 21 is located downward from the main body 20 and the inner cylinder 23 and the intermediate cylinder 25 are located upward from the main body 20. 2, the treated water inlet pipe 11 is connected in the eccentric direction to induce a centrifugal force to the centrifugal mixing tank 22 formed at the lower side of the cone cylinder 21. Accordingly, the wastewater is stirred in the order of the centrifugal mixing passage 22a, the primary upward passage 20a, the downward passage 20b, and the secondary upward passage 20c.

한편, 본 발명에 의하면 상기 본체(20)는 원추통(21)의 상측과 내통(23)의 하측 사이에 복수의 유입도관(31)을 구비한다. 유입도관(31)의 상류단은 원추통(21)의 외부 공간과 연통되도록 연결하고, 유입도관(31)의 하류단은 내통(23)의 하류 측에 연결한다. 유입도관(31)은 상류단이 하류단 보다 낮은 상향 경사를 이루도록 한다. 유입도관(31)의 수는 4개가 적절하지만 본체(20)의 용량에 따라 2~8개의 범위에서 선택할 수 있다. On the other hand, according to the present invention, the main body 20 is provided with a plurality of inlet conduit 31 between the upper side of the conical cylinder 21 and the lower side of the inner cylinder 23. The upstream end of the inlet conduit 31 is connected to communicate with the outer space of the cone cylinder 21, the downstream end of the inlet conduit 31 is connected to the downstream side of the inner cylinder (23). The inlet conduit 31 allows the upstream end to make a lower upward slope than the downstream end. The number of inlet conduits 31 is appropriate, but can be selected in the range of 2 to 8 depending on the capacity of the main body 20.

본 발명에 의하면 상기 내통(23)은 지그재그로 1차상향유로(20a)를 형성하기 위한 격판(32)을 구비한다. 내통(23)은 원통이 바람직하지만 각형통을 사용할 수도 있다. 격판(32)은 1차상향유로(20a) 상에서 일측과 타측으로 번갈아 부착된 상태로 지그재그 유로를 형성하여 완속교반을 수행한다. 내통(23)에서 격판(32)이 형성된 부분은 보수와 교체의 용이성을 확보하도록 별도의 플랜지(33)를 이용하여 분리 가능한 구조로 하는 것이 좋다. 내통(23)의 상측으로 동일한 높이에 다수의 통공(34)을 형성하여 상향 유동된 하폐수가 하강하여 하향유로(20b)로 진행하도록 한다.According to the present invention, the inner cylinder 23 is provided with a diaphragm 32 for forming the primary upward flow path 20a in a zigzag manner. Although the inner cylinder 23 is preferably a cylindrical cylinder, a square cylinder may be used. The diaphragm 32 performs a slow stirring by forming a zigzag flow path in a state where the diaphragm 32 is alternately attached to one side and the other side on the primary upward flow path 20a. In the inner cylinder 23, the portion where the diaphragm 32 is formed is preferably configured to be separated using a separate flange 33 to ensure ease of repair and replacement. A plurality of through holes 34 are formed at the same height as the upper side of the inner cylinder 23 so that the downflowed wastewater flows down and proceeds to the downward flow path 20b.

이때, 본 발명에 의한 내통(23)의 하측으로 폴리머투입관(16)이 연결되도록 한다. 폴리머는 하폐수의 응집력을 높이기 위한 것으로 내통(23)에서 격판(32)의 상류단(하측)으로 투입된다. 폴리머의 투입 직후에 격판(32)으로 완속교반을 수행함에 따라 오폐수에서 생성되는 플록이 손상이 없는 상태를 유지한다.At this time, the polymer injection tube 16 is connected to the lower side of the inner cylinder 23 according to the present invention. The polymer is introduced into the upstream end (lower side) of the diaphragm 32 from the inner cylinder 23 to increase the cohesive force of the wastewater. As the slow stirring is performed to the diaphragm 32 immediately after the injection of the polymer, the floc generated in the waste water remains intact.

본 발명에 의하면 상기 원추통(21)은 하향유로(20b) 상의 침전된 슬러지 부상을 방지하도록 내부 공간상에 부상방지판(36)을 구비한다. 부상방지판(36)은 역삼각형 형태로 형성되어 내통(23)의 저면에 별도의 지지대를 개재하여 고정한다. 하향유로(20b)를 통과하여 낙하되는 하폐수에서 생성되는 슬러지는 부상방지판(36)에 충돌한 후에 원추통(21)의 내부 공간 하단부에 수집된다. According to the present invention, the cone cylinder 21 is provided with an anti-floating plate 36 on the inner space to prevent the sludge injuries deposited on the downward passage (20b). The anti-floating plate 36 is formed in an inverted triangle shape and is fixed to the bottom of the inner cylinder 23 through a separate support.
