Abstract

본 발명은 폐수의 호기성 생물처리에 있어서의 산기장치에 관한 것으로, 보다 상세하게는 폭기조의 상방으로 부터 산소공급을 이루게 하여 정화효율에 영향을 미치는 인자중 용존산소농도를 소동력으로 유지하게 되어 경제적인 정화처리를 기대할 수 있는 폐수의 호기성 생물처리에 있어서의 산기장치에 관한 것이다.The present invention relates to aeration apparatus for aerobic biological treatment of wastewater, and more particularly, to an apparatus and a method for anaerobic biological treatment of wastewater, in which oxygen is supplied from above the aeration tank to maintain the dissolved oxygen concentration as a small power among factors affecting the purification efficiency, The present invention relates to aeration apparatus for aerobic biological treatment of wastewater which can be expected to be treated with phosphorus.

기 - 액 접촉면적을 늘리기 위한 방안으로 본 발명은 기포경을 수미크론단위 (25 - 50 micron)로 미세화시키므로서 액체중의 상승 속도가 2.5 - 3.0 ㎝/sec가 줄어짐과 동시에 액체와의 접촉면적을 늘리게 하며, 기 - 액 접촉시간을 늘리기 위한 방안으로 본 발명은 상기 기포를 미세화 발생시키는 방법이외에 하부가 개방된 격벽통을 폭기조내에 설치하고 격벽통의 상부에서 펌프 또는 임펠러등의 수단으로 폭기조 외부액 또는 내부액에 압력을 가해 밀어넣어 하향유속중 격벽통내에서 미세기포의 상승속도 (2.5 - 3.0 ㎝/sec) 보다 약간 크게 참으로써 격벽통내의 기포의 체류시간을 무한대로 조정 가능하게 한 것을 특징으로 한다.In order to increase the gas-liquid contact area, the present invention reduces the rising velocity of the liquid in the range of 2.5 to 3.0 cm / sec by micronizing the bubble diameter to several microns (25 to 50 microns) In order to increase the area and to increase the gas-liquid contact time, the present invention is also applicable to a method of increasing the gas-liquid contact time by providing, in addition to the method of generating the bubbles, a partition wall cylinder opened at the lower part in the aeration tank, (2.5 - 3.0 ㎝ / sec) in the bulkhead canister at the downward flow rate by applying pressure to the external liquid or the internal liquid, thereby making it possible to adjust the residence time of the bubbles in the bulkhead can be infinitely adjusted .

이에 따라 기존의 5 - 8%의 효율에 불과한 산소흡수효율을 대폭으로 향상시킬 수 있으며, 또한 소등력으로 폭기조내의 소요 용존산소농도를 유지할 수가 있어 경제적인 폐수정화처리를 기대할 수 있게 된다. 또한, 폭기조내의 부상하는 슬럿지를 순환 분산되게 하므로서 상기 부상하는 슬럿지에 따르게 되는 정화의 역효과를 해결할 수 있게 되며, 특히 기포의 상승속도보다 격벽통내의 기포, 액체의 혼합류의 하향류속을 더 크게 함으로서 격벽통내의 기포 체류 시간을 무한히 가능케 하는 효과가 있다.Therefore, it is possible to greatly improve the oxygen absorption efficiency, which is only 5 - 8% of the conventional efficiency, and to maintain the required dissolved oxygen concentration in the aeration tank with the extinguishing force, so that an economical waste water purification treatment can be expected. In addition, it is possible to solve the adverse effect of the purification depending on the floating sludge by circulating and dispersing the floating sludge in the aeration tank. In particular, by increasing the downward flow rate of the mixture of bubbles and liquid in the partition wall cistern than the rising speed of the air bubbles There is an effect that the bubble staying time in the partition wall can be infinitely made possible.
