Description
인간과 자연의 동식물에 절대적으로 필요한 수자원은 자연계의 순환으로 인한 자정작용에 의하여 원래의 청정수로 환원되어 인간과 자연의 동식물에 충족되었으나, 각종 산업사회의 발달, 인구의 증가 및 집중화에 따른 생활수준의 향상으로 수질오염문제는 날이 갈수록 더욱 악화되어 일부 생태계의 파괴는 물론 우리 인간생활에서도 조차 절대적으로 부족한 상태에 이르렀다. 수자원이 부족한 현실에서도 우리가 사용한 물들(각종 오 폐수, 축산, 분뇨폐수)을 하천과 바다에 그대로 유출하거나 또는 재사용할 수 없도록 미흡하게 처리해 방류함으로써 더욱 더 수자원의 고갈을 초래하고 자연 생태계를 파괴하고 있다.The water resources absolutely necessary for the animals and plants of nature and nature were reduced to the original clean water by the self-cleaning action of the natural cycle, but the animals and plants of human and nature were satisfied.However, the standard of living according to the development of various industrial societies, the increase and the concentration of the population The problem of water pollution has become worse with the improvement of Korea, and it has reached an absolute shortage not only in the destruction of some ecosystems but also in our human lives. Even in the realities of lack of water resources, the waste water, various livestock, and manure waste waters that we used (leakage, livestock, and manure waste water) are discharged to the rivers and the seas without being disposed of or reused, resulting in the depletion of water resources and the destruction of natural ecosystems. have.

이하 도면을 참조하여 본발명의 구성 및 작용을 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 오폐수 처리장치를 나타내는 개략도로서, 도면부호 1은 스크린을나타낸다. 상기 스크린은 일반적인 체와 유사한 것으로서, 각종 협잡물이 포함된 원폐수의 유입으로 인하여 다음 공정의 기계의 부하 및 공정상의 부하를 초래하는 입자가 큰 부유물(직경 2mm 이상의 협잡물 : 실, 나뭇잎, 머리카락, 씨앗류등)을 제거하는 기능을 가지고 있으며, 상기 스크린(1)은 집수조(2)에 연통되어 있다.1 is a schematic diagram showing a wastewater treatment apparatus of the present invention, wherein reference numeral 1 denotes a screen. The screen is similar to a general sieve, and has a large particle suspended matter (clumps of 2 mm or more in diameter: thread, leaves, hair, seeds, etc.) which causes the load of the machine and the process load of the next process due to the inflow of raw waste water containing various contaminants. Etc.), and the screen (1) is in communication with the sump (2).
상기 집수조(2)의 하부에는 초음파에어장치(22)에 연결되어 있는 초음파폭기장치(4)(5)가 설치되어 있으며, 상기 초음파폭기장치(4)(5)는 3Kg의 고압력에서 18.000Hz 이상의 초고주파가 발생되도록 하여 폭기시키는 장치로서 종래의 전극을 이용한 진동방법이 아닌 공기로서 발생되는 초음파기를 사용한다. 상기 집수조(2)의 상부에는 피라밋산화장치(6)를 설치하고, 상기 피라밋산화장치(9)와 집수조(2)를 연결순환시키는 피라밋순환펌프(9)를 설치하여 연속적으로 원수가 순환함으로 인하여 산화,분해 및 산소공급을 효과적으로 이루어 지도록 하는 장치이며, 이로 인하여 산화, 분해 및 산소공급을 효과적으로 이루어 지도록 하는 장치이다.In the lower part of the water collecting tank 2, ultrasonic aeration devices 4 and 5 connected to the ultrasonic air device 22 are installed, and the ultrasonic aeration devices 4 and 5 are 18.000 Hz or more at a high pressure of 3 Kg. Ultrasonic waves are generated so that the aeration is not an oscillation method using a conventional electrode but an ultrasonic wave generated as air. The pyramid oxidation unit 6 is installed on the top of the sump tank 2, and the pyramid circulation pump 9 for circulating the pyramid oxidation unit 9 and the sump tank 2 is installed to continuously circulate raw water. It is a device to effect oxidation, decomposition and oxygen supply effectively, and thus the device to effect oxidation, decomposition and oxygen supply effectively.
이로 인하여 집수조(2)에서는 계속적인 산화,분해 및 폭기가 동시에 일어나 다음단계 응집부상 여과조(15)에서 처리할 수 있는 응집부상효과를 최대한 발휘하게 하는 역할을 하는데 그 중요성이 있다.Because of this, the collection tank (2) has a significant role in maximizing the effect of flocculation injuries that can be processed in the next stage flocculation flotation filtration tank (15) by the continuous oxidation, decomposition and aeration.
