도 1에 도시된 바와 같이 본 발명에 따른 우수의 비점오염원 처리 장치는 1단 여과조(100), 2단 여과조(200), 배출관(300) 및 역세수 저장조(400)를 포함하여 이루어진다.As illustrated in FIG. 1, the apparatus for treating non-point source of rainwater according to the present invention includes a first stage filtration tank 100, a two stage filtration tank 200, a discharge pipe 300, and a backwash water storage tank 400.

도 1에 도시된 실시예는 제1 여과조(100)가 중심에 위치하고, 제2 여과조(200)가 외측에 설치되는 구조이다.1 is a structure in which the first filtration tank 100 is located at the center and the second filtration tank 200 is installed at the outside.

먼저, 제1 여과조(100)는 우수 저장조부터 유입되는 우수를 상측에서 제1여과층부(110)를 통과시켜서 하부로 보내는 역할을 한다.First, the first filtration tank 100 serves to send the rainwater flowing from the rainwater storage tank to the lower portion through the first filtration layer 110 from the upper side.

상기 제1 여과조(100)는 하부가 개구된 원통 형태이며, PE재질의 제1여과층부가 형성되어 우수에 포함된 부유물질 등을 걸러준다.The first filtration tank 100 is in the form of a cylindrical opening with a lower portion, the first filtration layer of the PE material is formed to filter the suspended substances contained in the rain.

이러한 상기 1단 여과조(100)의 상부에는 우수 저장조로부터 유입되는 우수를 걸러주는 스트레이너(130)가 설치되고, 유입되는 우수의 양을 측정하기 위한 레벨 센서(120)가 설치된다.The upper portion of the first stage filtration tank 100 is provided with a strainer 130 for filtering the rainwater flowing from the rainwater reservoir, and a level sensor 120 for measuring the amount of rainwater flowing in.

다음으로, 2단 여과조(200)는 상기 1단 여과조(100) 외측에 설치되어 상기 1단 여과조(100) 하부로부터 유입되는 우수를 제2여과층부(210)를 통과시켜서 상부에 형성된 방류관(230)을 통해서 방류시키게 된다.Next, the two-stage filtration tank 200 is installed on the outside of the first stage filtration tank 100 through the second filtration layer portion 210 through the rainwater flowing from the lower portion of the first stage filtration tank 100 formed in the upper discharge pipe ( 230).

상기 2단 여과조(200)에 설치되는 제2여과층부(210)는 스펀지 재질로 이루어지고, 상기 2단 여과조(200) 내부에서 상하로 이동되도록 결합된다.The second filtration layer 210 installed in the two-stage filtration tank 200 is made of a sponge material, and is coupled to move up and down inside the two-stage filtration tank 200.

그리고, 상기 1단 여과조(100) 하부에는 배출관(300)이 설치되고, 상기 배출관(300)을 통해서 배출되는 역세수를 저장하는 역세수 저장조(400)를 포함한다.In addition, a discharge pipe 300 is installed below the first stage filtration tank 100 and includes a backwash water storage tank 400 for storing the backwash water discharged through the discharge pipe 300.

우수의 전체적인 흐름을 살펴보면, 우수 저장조로부터 유입되는 우수는 스트레인너(130)를 거쳐서 1단 여과조(100)로 유입되고, 1단 여과조(100)에서 제1여과층을 통과해서 개구된 1단 여과조(100)의 하부로 유입된다.Looking at the overall flow of rainwater, rainwater flowing from the rainwater storage tank is introduced into the first stage filtration tank 100 through the strainer 130, the first stage filtration tank opened through the first filtration layer in the first stage filtration tank 100. Inflow to the bottom of the (100).

1단 여과조(100) 하부와 연결된 2단 여과조(200)에서 상측에 위치된 제2여과층부(210)을 통해서 상측으로 배출되고, 일정한 유량 이상이 유입되면 방류관(230)을 통해서 배출된다.In the second stage filtration tank 200 connected to the lower stage of the first stage filtration tank 100 is discharged to the upper side through the second filtration layer 210 located on the upper side, and discharged through the discharge pipe 230 when a predetermined flow rate or more is introduced.

여기서, 상기 제1여과층부(110)는 제2여과층부(210)보다 공극율이 높은 것으로 제작되어야 한다.Here, the first filtration layer 110 should be manufactured to have a higher porosity than the second filtration layer 210.

즉, 제1여과층부(110)를 통과한 이물질은 중에서 제2여과층부를 통과하지 못하는 것은 1단 여과조 하부로 모이게 되고, 모여진 이물질은 배출관(300)을 통해서 하부의 저장조(400)로 배출된다.That is, the foreign matter that has passed through the first filtration layer unit 110 is not able to pass through the second filtration layer is collected in the lower stage of the first filtration tank, the collected foreign matter is discharged to the storage tank 400 of the lower through the discharge pipe 300. .

부가적으로, 제1여과층부(110)를 통과하고 제2여과층부(210)를 통과하지 못한 이물질이 순간적으로 급증하는 경우 우수 저장조로 역류되거나, 비교적 깨끗한 우수가 유입되어 별도의 오염원 처리가 불필요한 경우에 제2여과층부를 거치지 않고 바로 배출될 수 있도록 별도의 비상방류배관(320)을 설치한다.In addition, when the foreign matter that has passed through the first filtration layer 110 and failed to pass through the second filtration layer 210 instantaneously increases, it is flowed back to the rainwater reservoir, or a relatively clean rainwater flows in, so that it is unnecessary to treat a separate pollutant. In this case, a separate emergency discharge pipe 320 is installed to be discharged immediately without passing through the second filtration layer part.

본 발명에 따른 다른 실시예에 대해 살펴보기로 한다.Another embodiment according to the present invention will be described.
