통상적으로 정수장, 폐수처리장, 하수처리장 등의 상/하수처리장(100)으로 유입되는 유입수는 전단계에서 용수에 썩인 슬러지를 제거하기 위해 소석회 등의 침전제를 투입하여 믹서기로 썩은 후 바닥에 침전시키고 이 슬러지를 제거하게 된다. 상기 과정에서 용수의 수면에 다량의 거품이 발생하게 되고 다음의 침전지(102)로 유입된다. 상기 침전지(102)에서는 수면에 떠있는 거품 및 오니찌꺼기 등의 부유물을 제거한 후 다음 공정인 2차 침전지 또는 약품처리장으로 흘러들어 가게 된다.Typically, the inflow of water into the water / sewage treatment plant 100, such as a water purification plant, a wastewater treatment plant, and a sewage treatment plant, is precipitated on the bottom of the sludge by adding a precipitant such as slaked lime to remove the sludge from the water in the previous stage, and then settling it to the bottom. Will be removed. In the above process, a large amount of bubbles are generated on the surface of the water and flows into the next settling basin 102. In the sedimentation basin 102, floating matters such as bubbles and sludges floating on the water are removed and then flowed into a second sedimentation basin or a chemical treatment plant.

상기의 부유물을 제거하기 위해 호스, 파이프 등의 장애물을 수면에 띄워 놓고 부유물을 일측으로 끌어 모아서 작업자가 용기에 담아 내거나 흡입장치와 연결된 흡입구를 통해 부유물을 흡입하여서 외부로 배출하는 작업이 이루어졌다.In order to remove the float, an obstacle such as a hose, a pipe, etc. was floated on the water surface, and the float was collected to one side, and a worker was put in a container or sucked the float through the suction port connected to the suction device and discharged to the outside.

그러나 대부분이 작업자로 하여금 수작업으로 이루어지고 지속적인 관리가 필요할 뿐만 아니라, 상기 부유물의 제거가 미흡할 뿐만 아니라 미쳐 제거되지 못한 부유물이 다음 공정으로 흘러들어 감에 따라 용수의 정수효율이 떨어지는 문제점이 있었다.However, most of them are made by a worker by hand and require continuous management, and there is a problem that the water purification efficiency of water is lowered as not only the removal of the floating material is insufficient but also the missing floating material flows into the next process.

따라서 상기한 바와 같은 문제점을 해결하기 위한 본 고안의 목적은 용수의 수면에 떠있는 부유물의 흐름을 차단하여 제한된 공간에 모이도록 하여 호퍼를 통해 자연스럽게 배출되도록 하는 상/하수처리장의 부유물 처리장치를 제공함에 있다.Therefore, an object of the present invention for solving the problems as described above is to provide a float treatment device of the water / sewage treatment plant to block the flow of the floating float on the water surface to collect in a limited space to be naturally discharged through the hopper. Is in.

또한, 본 고안의 목적은 침전지로 유입되는 수위의 변화에 따라 부유물이 배출되는 호퍼의 높낮이를 조절할 수 있는 상/하수처리장의 부유물 처리장치를 제공함에 있다.In addition, an object of the present invention is to provide a floatation treatment apparatus of the water / sewage treatment plant that can adjust the height of the hopper to discharge the float in accordance with the change in the water level introduced into the sedimentation basin.
