It is preferable to form a guide piece 115 to guide the passage down and the lower portion of the lower passage to the left and right to guide the sewage or wastewater to the lower side uniformly from side to side.

상기 침전조(120)는 상단에 웨어(122)가 형성된 가이드편(121)을 형성하고, 중앙에는 돌출부(126)를 형성하여 유입되는 하수 또는 폐수를 침전조(120)의 좌우 측으로 유도하며, 좌우 바닥면에 침전된 이물질을 배출하는 밸브가 부착된 슬러지배출관(124)을 결합한다.The sedimentation tank 120 forms a guide piece 121 having a weir 122 formed at the top thereof, and forms a protrusion 126 at the center to guide the sewage or wastewater introduced to the left and right sides of the sedimentation tank 120, and to the left and right bottoms. The sludge discharge pipe 124 is attached to the valve is attached to discharge the foreign matter precipitated on the surface.

또한, 침전조(120)의 외향 측벽은 경사벽(125)으로 형성하여 침전물질이 슬러지배출관(124)측으로 원활하게 집진할 수 있도록 하되 경사벽(125)에 개폐문이 형성된 출입구(123)를 형성하여 청소나 보수 등을 위하여 내부를 출입이 가능하도록 함이 바람직하다.In addition, the outward sidewall of the settling tank 120 is formed by the inclined wall 125 to allow the sedimentation material to be smoothly collected to the sludge discharge pipe 124 side, but forms an entrance 123 having an opening and closing door formed on the inclined wall 125. It is desirable to allow access to the interior for cleaning or maintenance.

여기서 돌출부(126)는 삼각, 사각 및 원형 등으로 형성할 수 있다. The protrusion 126 may be formed in a triangular, square, circular, and the like.

상기 응집유도필터(130)는 침전조(120)의 좌우에 다수개 경사플레이트(131)를 순차적으로 일정하게 설치하되 경사플레이트(131)의 하단이 응집통로(112)의 하강통로 하단보다 상측에 위치하도록 형성하여 하부로 유도된 하수 또는 폐수가 다수개의 경사플레이트(131)를 원활하게 통과하도록 유도하므로 하수 또는 폐수에 함유된 이물질을 효과적으로 응집하여 원활하게 침강시킬 수 있도록 함이 바람직하다.The flocculation induction filter 130 is installed on the left and right of the settling tank 120, the plurality of inclined plates 131 sequentially and the lower end of the inclined plate 131 is located above the lower end of the downcoming passage 112 Formed so as to guide the sewage or wastewater guided to the bottom smoothly through a plurality of inclined plates 131, it is preferable to effectively settle the sediment or sediment contained in the sewage or wastewater smoothly.

한편 상기 혼화조(110)의 역삼각부(114)와 응집통로(112), 침전조(120)의 돌출부(126)와 경사벽(125), 응집유도필터(130)의 경사플레이트(131)의 경사각은 상호 동일하게 하여 하수 또는 폐수처리장치(100)를 효율적으로 제작할 수 있도록 함이 바람직하다.Meanwhile, the inclination angles of the inverted triangular portion 114 and the aggregation passage 112 of the mixing tank 110, the protrusion 126 and the inclined wall 125 of the precipitation tank 120, and the inclined plate 131 of the cohesion induction filter 130 are described. It is preferable to be able to efficiently manufacture the sewage or waste water treatment apparatus 100 by the same as each other.

이러한 본 발명의 하수 및 폐수처리장치는 혼화조(110)에 교반블레이드(111)를 회전시키면서 응집제 등의 약품을 투입하여 하수 또는 폐수와 약품을 골고루 혼합하여 원활하게 반응할 수 있도록 한다.The sewage and wastewater treatment apparatus of the present invention, by rotating the stirring blade 111 in the mixing tank 110, by inputting a chemical such as flocculant so that the sewage or wastewater and chemicals evenly mixed to react smoothly.

여기서 약품이 투입된 하수 또는 폐수는 화학 반응하여 응집되면서 응집통로(112)로 유도되고, 응집통로(112)로 유도된 하수 또는 폐수는 응집통로(112)가 경사지게 형성되어 내주연에 지속적으로 상호 부딪힘이 발생하게 응집효율이 증가시킬 뿐만 아니라, 더욱이 응집통로(112)의 상단에서 보조응집편(113)에 의하여 하수 또는 폐수 내의 이물질이 걸려 응집효율이 더욱 증가한다.Here, the sewage or wastewater into which the chemical is injected is agglomerated by a chemical reaction and is led to the agglomeration passage 112, and the sewage or wastewater induced by the agglomeration passage 112 is formed to be inclined to the agglomeration passage 112 to be continuously bumped into the inner circumference. Not only does this increase the coagulation efficiency, but also the coagulation efficiency is further increased by being caught by foreign matter in the sewage or waste water by the secondary flocculation piece 113 at the top of the coagulation passage (112).

한편, 응집통로(112)를 통과한 하수 또는 폐수는 침전조(120)의 하부로 유도되고, 침전조(120)에 유도된 하수 또는 폐수는 일부 응집된 이물질이 하부로 침강되며, 하수 또는 페수는 서서히 상승하게 된다.On the other hand, the sewage or wastewater that has passed through the flocculation passage 112 is guided to the lower portion of the sedimentation tank 120, the sewage or wastewater induced in the sedimentation tank 120 is partially condensed foreign material is settled to the lower portion, sewage or wastewater gradually Will rise.

이때 침전조(120)의 내부에 형성된 응집유도필터(130)의 다수개의 경사플레이트(131) 사이 통로를 하수나 폐수가 통과하면서 상승하므로 하수 또는 폐수 내의 대부분 이물질이 경사플레이트(131)의 경사면에 부딪히게 되고, 이로 인하여 효과적으로 이물질이 응집되어 하부로 침강하며 이물질을 제거한 처리수만 상승하여 웨어(122)가 다수개 형성된 처리수배출구(121)를 통해 배출되므로 응집과 침강 효율을 극대화하여 대량의 하수 또는 폐수를 단시간 내에 처리할 수 있도록 하는 것이다.
At this time, as the sewage or wastewater rises through the passage between the plurality of inclined plates 131 of the flocculation induction filter 130 formed in the sedimentation tank 120, most foreign substances in the sewage or wastewater hit the inclined surface of the inclined plate 131. Due to this, effectively condensation of foreign matters is settled to the lower portion and only the treated water which removes the foreign matter rises and is discharged through the treated water outlet 121 formed with a plurality of ware 122 to maximize the flocculation and sedimentation efficiency to maximize the amount of sewage or The wastewater can be treated in a short time.
