Abstract

PURPOSE: An apparatus for treating sewage/wastewater by multiplication control of vorticella using natural aeration is provided. Generally vorticella is increased in case of high treatment efficiency of sewage/wastewater, so conventional treatment plants propagate vorticella. However, vorticella interrupts propagation of other microorganism. The apparatus is characterized by restraining propagation of vorticella for propagating other microorganism using natural aeration. CONSTITUTION: The apparatus comprises a biomembrane reactor(17) in which biomembranes(3,4,5) and an air contact biomembrane(2) are installed; a sedimentation tank(7) for solid separation; a circulation pump(9) for circulating supernatant water of the sedimentation tank(7) into the biomembrane reactor(17); a nozzle pipe(1) for transporting supernatant water into the upper part of the biomembrane reactor(17); and an overflow tank(14) for storing final treated water through a weir(11). Sewage/wastewater is injected into the biomembrane reactor(2) by gravity, so sewage/wastewater is aerated naturally.

본 발명은 생물막법에 의한 수처리에 있어서 생물막에 서식하는 미생물중 특정미생물의 증식을 억제하여 처리 효율을 향상시키는 데 그 목적이 있다.An object of the present invention is to improve the treatment efficiency by inhibiting the proliferation of specific microorganisms among the microorganisms inhabiting the biofilm in the water treatment by the biofilm method.

상기목적을 달성하기 위하여 생물막법에 의한 수처리시 수처리가 양호할 때 종벌레(vorticella)가 출현한다 하여 종벌레를 많이 증식시키나 본 발명은 종벌레 증식억제를 통하여 수중의 유기물, 질소, 인을 처리하는 것을 특징으로 한다.In order to achieve the above object, when the water treatment is good during the water treatment by the biofilm method, the worms appear (vorticella) to multiply the worms, but the present invention is characterized by treating organic matter, nitrogen, and phosphorus in the water through the inhibition of the worm growth. It is done.

그간의 폐수처리는 산소 전달율, 포기용 송풍기 전력사용 절감등을 이유로 용존산소 농도를 0.5ppm 정도로만 유지시켜 관리하여 종벌레를 포함한 미생물을 위해 용존 산소 2ppm이상 유지하는 것이 불가능하였으나 자연포기에 의한 수처리시는 용존산소를 용이하게 조절하여 특정 미생물, 종벌레의 증식을 억제하므로써 폐수처리 효율을 극대화시킬 수 있다. 이때 처리수질은 양호하나 종벌레는 거의 관찰되지않는다. 종벌레는 미생물의 섭식능력이 뛰어나 종벌레 증식을 억제 할 경우 종벌레보다 유기물 처리 능력이 뛰어난 여타 미생물을 보호 할 수 있게 되어 처리효율이 향상된다.In the meantime, wastewater treatment was maintained by maintaining only about 0.5ppm dissolved oxygen concentration for reasons of oxygen transfer rate and abandonment blower power use, and it was impossible to maintain more than 2ppm dissolved oxygen for microorganisms including insects. Easily control the dissolved oxygen to inhibit the growth of certain microorganisms, insects can maximize the efficiency of wastewater treatment. At this time, the treated water quality was good, but few species were observed. The species of insects have excellent feeding ability of microorganisms, and when they suppress the growth of insects, they can protect other microorganisms that have better organic treatment than the insects.
