Abstract

본 발명은 최종 침전조에서 응집제를 사용하여 폐수를 정화함에 있어서, 폭기조에서 침전조로 이송되는 배관에 30㎜ 이하의 직경의 이중벽 파이프를 연결하고, 이중벽 파이프 내벽에 직경 10㎜ 이하의 분사노즐을 다수 설치하고, 이중벽 파이프에는 펌프 혹은 자연구배로 응집제를 투입하는 응집제 투입장치를 설치한 것을 특징으로 하는 폐수정화 장치를 제공하는 것으로, 본 발명의 폐수정화 장치를 이용하여 페수를 정화하는 경우에는 벌킹을 거의 일으키지 않게 되어 잉여오니의 침강성 및 여과성이 현저하게 개선되기 때문에 법적기준치 이내의 수질이 유지되도록 할 수 있는 이점이 있다.In the present invention, in purifying wastewater using a flocculant in a final sedimentation tank, a double wall pipe having a diameter of 30 mm or less is connected to a pipe transferred from an aeration tank to a sedimentation tank, and a plurality of injection nozzles having a diameter of 10 mm or less are installed on an inner wall of the double wall pipe. The double wall pipe is provided with a coagulant injector for injecting a coagulant into a pump or natural gradient. The wastewater purification device is provided. When the wastewater is purified using the wastewater purification device of the present invention, bulking is almost eliminated. Since the sedimentation and filterability of the surplus sludge is remarkably improved, the water quality within the legal standard value can be maintained.
