상기 마이크로 바 스크린부를 통과한 유입수는 원형 침전조부로 투입시켜 임펠러에 의한 원심력으로 상등수는 유출로를 통해 후처리 장치로 배출시키고, 흙이나 모래 등의 침사물은 중앙에 모이게 하여, 중앙에 설치된 토네이도 블럭에서 발생한 토네이도에 의해 상부로 상승시켜 침사 세정부로 흡입시킨 뒤,The inflow water passing through the micro bar screen part is introduced into the circular sedimentation tank part, and the supernatant water is discharged to the aftertreatment device through the outflow path by centrifugal force by the impeller, and the sediments such as soil or sand are collected in the center, and the tornado block is installed at the center.

일관되게 진행되는 전처리 공정으로 유입수에서 협잡물과 침사물을 보다 효율적으로 분리 제거시킬 수 있도록 한 것이다.This is a consistent pretreatment process that allows for more efficient separation and removal of contaminants and sediments from the influent.
일반적으로 상,하수 및 폐수 등은 수처리 과정에서 전처리 공정으로 상,하수및 폐수 등에 포함된 슬러지 등의 각종 협잡물과 흙이나 모래 등의 침사물을 분리 제거시키는 과정이 필요하다.In general, water, sewage, and waste water are required to separate and remove various contaminants such as sludge and water or sediment contained in water, sewage, and waste water as a pretreatment process in a water treatment process.
이를 위하여 지금까지는 여러 다양한 방법으로 협잡물과 침사물을 수거하기 위한 슬러지 수집기와 침사 인양기 들이 제시되고 있으나, 협잡물 및 침사물 수거 시설이 각각 이원화되어 있었기 때문에, 처리 시설과 공정이 복잡해지고, 많은 소요 부지가 필요하게 되어 부지 조건에 제한을 받게 되는 경우가 많았고, 그에 따라 많은 수처리 비용이 요구되는 폐단이 있었다.To this end, sludge collectors and sedimentary lifting devices have been proposed for collecting contaminants and sediments in various ways. However, since the contaminants and sediment collection facilities were dualized, treatment facilities and processes became complicated and required. In many cases, the site was required to be restricted by the site conditions, resulting in a lot of water treatment costs.
즉, 종래에는 직사각형의 긴 수로를 형성하여 수로 길이와 동등한 수평 스크류 컨베이어에 의해 포집된 침사물을 경사 스크류 컨베이어로 인양하는 방식을 취하고 있었기 때문에, 많은 부지가 필요하게 된다.That is, since a conventional long channel is formed and the sediment collected by the horizontal screw conveyor equal to the length of the channel is lifted by the inclined screw conveyor, many sites are required.
또한 다량의 토사 유입 등에 따른 매몰 방지용 장치를 별도로 설치해야 하는 부담이 있었다.In addition, there was a burden of separately installing a device for preventing investment due to the inflow of large amounts of soil.
본 고안은 이와 같은 종래의 상,하수 및 폐수 등의 종합 전처리 장치가 갖고 있는 제반 문제점을 해소하기 위하여 연구된 것으로서,The present invention has been studied to solve all the problems of the conventional pretreatment device such as water, sewage and wastewater,

본 고안의 또 다른 목적은 일관된 공정으로 상,하수 및 폐수 등에서 슬러지 등의 각종 협잡물과 흙이나 또는 모래 등의 침사물을 분리 수거할 수 있는 상,하수 및 폐수 등의 종합 전처리 장치를 제공하는데 있다.It is another object of the present invention to provide a comprehensive pretreatment apparatus for water, sewage, and wastewater that can separate and collect various contaminants such as sludge and sediment such as soil or sand in water, sewage, and wastewater in a consistent process. .
이와 같은 목적을 달성하기 위하여, 본 고안은 상,하수 및 폐수 등으로 구성된 유입수를 마이크로 바 스크린부로 유입시켜, 유입수에 포함된 협잡물을 마이크로 바 스크린으로 분리 수거하여 압착 탈수 스크류 컨베이어로 압착 수거하는 한편, 탈수여액은 유입수로로 반송시키고,In order to achieve the above object, the present invention introduces inflow water consisting of water, sewage, and wastewater into the microbar screen unit, and separates and collects the contaminants contained in the inflow water using a microbar screen, and then press-collects the compressed dewatering screw conveyor. , Return the dewatering liquid to the influent channel,
