미세기포를 적용하여 폐수처리를 하는 기술이 출시되고 현장에 적용되고 있다.Wastewater treatment technology using micro bubbles has been released and applied to the site.
현재 적용되고 있는 마이크로버블발생 장치를 적용한 폐수처리장치는 마이크로버블발생장치를 만들기 위해 [문헌 1],[문헌 3]과 같이 고가의 가압용 탱크를 만들어야 하는 문제점이 있다. The wastewater treatment apparatus applying the microbubble generating device currently applied has a problem of making an expensive pressurizing tank as in [Document 1] and [Document 3] to make the microbubble generating device.
또, 상기의 가압용 탱크를 피하기 위해서 [문헌2]와 같이 쓰는 경우는 장치가 오히려 더 복잡해지고 기름이 섞인 폐수처리 시스템에만 적용되는 단점이 있다. In addition, in order to avoid the pressurization tank as described in [2], there is a disadvantage that the apparatus is more complicated and is applied only to the wastewater treatment system in which oil is mixed.
상기의 문제점을 해결하기 위해서 마이크로버블이 발생되는 펌프와 안정된 마이크로버블 유지를 위한 용존탱크를 적용하여 약품처리조에서 통과된 폐수를 폐수부상분리조에서 적용시켜 스컴을 제거하는 특징을 갖는 마이크로버블장치적용 폐수처리시스템In order to solve the above problems, a microbubble device having a feature of removing scum by applying wastewater passed from a chemical treatment tank to a wastewater flotation separation tank by applying a pump that generates microbubbles and a dispensing tank for maintaining stable microbubbles. Applied Wastewater Treatment System

본 발명은 폐수처리에 적용되는 응집조의 침전된 슬러지(유기물로된 플럭뭉치)에 적용되거나 또는 폐절삭유처리장치에 적용되는 기름과 물을 분리하는 약품 섞임조에서 기름입자에 적용되어 부상분리법으로 제거하기 위해 구성되는 마이크로발생용 펌프와 용존탱크와 마이크로버블발생량 콘트롤장치와 폐수부상분리조와 스컴제거장치와 폐수 재활용조로 구성된 것을 특징으로하는 폐수 및 폐절삭유처리시스템에 관한 것으로서 다음과 같은 기존 기술 우위의 특징을 갖는다.The present invention is applied to oil particles in a chemical mixing tank separating oil and water applied to sedimented sludge (organic floc bundle) of an agglomeration tank applied to wastewater treatment, or applied to a waste cutting oil treatment apparatus, and removed by flotation. The present invention relates to a wastewater and waste cutting oil treatment system comprising a microgeneration pump, a dispensing tank, a microbubble generation control device, a wastewater flotation tank, a scum removal device, and a wastewater recycling tank configured to Has characteristics.
1) 컴팩트한 구성의 마이크로버블 발생장치 : 근래에 실용화되고 있는 밀폐형 임펠라방식을 응용하여 개발된 마이크로버블 발생용 펌프를 적용하고 여기에서 발생된 마이크로버블이 물과 좀더 세밀하게 섞일 수 있게 파이프를 감아 만든 구조의 용존탱크를 적용하여 균일한 마이크로버블 용수가 스컴에 적용되기 위해 구성되고 이 마이크로버블 용수를 약품 섞임조에서 나오는 폐수에 섞어 폐수부상분리조에서 마이크로버블이 폐수로부터 스컴으로 부상되게 함으로서 기존의 가압탱크를 적용한 마이크로버블장치에 비해 간단하고 컴팩트한 구조를 갖는다. 또한 마이크로버블용 펌프의 용량과 발생량 조절장치에 의해 마이크로버블 발생량을 임의로 조정이 가능하기 때문에 폐수의 용량에 맞추기가 용이한 장점이 있다.1) Compact microbubble generating device: Apply microbubble generating pump developed by applying the closed-type impeller method that has been put to practical use in recent years, and wind the pipe so that the microbubbles generated here can be mixed with water more finely. By applying the dissolved tank of the structure, the uniform microbubble water is configured to be applied to scum, and the microbubble water is mixed with the wastewater from the chemical mixing tank and the microbubble is floated from the wastewater to scum in the wastewater flotation tank. Compared to the microbubble device using the pressurized tank, it has a simple and compact structure. In addition, since the microbubble generation amount can be arbitrarily adjusted by the capacity and generation amount control device of the microbubble pump, there is an advantage that it is easy to match the capacity of the wastewater.
2) 폐수의 재활용 구조 : 플럭이나 기름입자에 붙어 부상시켜 제거하기 위해 투입시키는 마이크로버블발생장치에 산소발생기를 용이하게 적용할 수 있는 구성에 의해 용수에 마이크로 버블화된 산소입자를 넣어줌에 의해 부상분리 뿐만이 아니라 산소를 투입하여 폐수를 정화시키는 능력을 좀더 강화할 수 있는 특징을 가지고 있다.2) Recycling structure of wastewater: By putting microbubble oxygen particles into the water by the structure that can easily apply the oxygen generator to the microbubble generating device that is injected to remove flotation or oil particles. As well as flotation, it is characterized by further strengthening the ability to purify wastewater by introducing oxygen.
