Description
본 발명은 폐수처리장에서 처리되어 방류되는 처리수를 최종적으로 처리하는 여과기에 관한 것으로, 특히 모래가 이송되는 양사관상에 오존을 공급하여 유기물을 산화분해시킴과 동시에 초음파 발생기를 설치하여서 음파에 의해 모래에 부착된 난분해성물질(잔여응집제 및 유분)을 2차로 분해시키고, 모래세정부로 설치된 초음파 발생봉에서 조사되는 음파에 의해 모래에 부착된 잔여부유물을 2차분리시켜 모래의 세척효율을 높임과 동시에 최종처리수의 정화 효율을 높인 초음파를 이용한상향류식 여과기에 관한 것이다.The present invention relates to a filter for finally treating the treated water discharged from the wastewater treatment plant, and in particular, by supplying ozone to both pipes to which sand is transported, oxidatively decomposes organic matter and installs an ultrasonic generator to sand by sound waves. Secondly decomposes hard-decomposable substances (residue coagulants and oil) attached to them, and separates the residues attached to sand by sound waves irradiated from the ultrasonic wave generating rod installed in sand washing machine to improve sand washing efficiency. At the same time, the present invention relates to an upflow filter using ultrasonic waves, which improves the purification efficiency of the final water.
일반 가정 또는 산업 현장에서 발생되는 폐수는 폐수처리장의 여러 정화단계를 거쳐 정화하게 되고, 정화되어진 처리수는 재활용하거나 방류하게 된다.Wastewater generated in general household or industrial sites is purified through various purification stages of the wastewater treatment plant, and the treated water is recycled or discharged.
상기와 같이 재활용하거나 방류되어지는 처리수에는 처리장의 정화과정에서 미처리되어진 잔여 부유물을 여과기를 이용하여 최종 제거하게 된다.As described above, the treated water that is recycled or discharged is finally removed by using a filter to remove the unsustained suspended matter in the purification process of the treatment plant.
폐수처리장에서 처리된 처리수 내의 잔여 부유물을 제거하는 상향류식 여과기에 의해 이루어지게 된다.This is accomplished by an upflow filter to remove residual suspended matter in the treated water from the wastewater treatment plant.
상기의 상향류식 여과기에 의해 원수가 처리되는 과정을 개략적으로 설명하면 다음과 같다.The process of raw water treatment by the upflow filter described above is as follows.
폐수처리장에서 처리된 폐수는 폐수내에 잔존해 있는 유기물 및 기타의 오염물질(SS)을 처리하기 위해 처리수를 모아 응집제에 의한 응집반응을 거쳐 원수라인을 통해 상향류식 처리조의 하부로 유입되어 처리조의 내부로 충진되어진 모래를 통과하는 과정에서 최종처리수에 잔존하는 부유물이 모래에 부착 제거됨과 동시에 부유물이 제거된 여과수(처리수)는 처리조의 상부로 부상하여서 처리조의 상부로 설치되어진 여과수(처리수)배출라인을 통해 배출되어지게 된다.The wastewater treated in the wastewater treatment plant collects the treated water to treat organic matter and other contaminants (SS) remaining in the wastewater, undergoes flocculation by flocculant and flows into the bottom of the upflow treatment tank through the raw water line. In the process of passing the sand filled inside, the floating water remaining in the final treated water is attached to and removed from the sand, and the filtered water (treated water) from which the suspended solids are removed rises to the upper part of the treatment tank and is installed in the upper part of the treatment tank. It is discharged through the discharge line.
한편, 최종처리수에 혼합되어 있는 부유물이 부착되어 오염되어진 모래는 처리조의 하부로 설치되어진 모래수집장치의 펌핑작동에 의하여 양사관을 통해 에어가 공급되는 에어라인으로 공급되어 처리조 내부로 다시공급되어지게 되는데, 에어라인상에 설치되어진 세정기의 주름관을 통과하면서 모래에 부착되어진 부유물이 제거되어짐과 동시에 제거된 부유물은 상부로 부상하여서 부유물배출라인을 통해배출되어지게 되는 것이다.On the other hand, the sand contaminated by the suspended solids adhering to the final treatment water is supplied to the air line through which the air is supplied through the pipes by the pumping operation of the sand collecting device installed at the bottom of the treatment tank, and then supplied again into the treatment tank. As the floats attached to the sand are removed while passing through the corrugated pipe of the scrubber installed on the air line, the suspended matter floats to the top and is discharged through the float discharge line.
상기와 같이 처리조내의 모래를 지속적으로 순환시켜 모래에 부착된 부유물을 제거해가면서 최종처리수를 정화 처리하는 종래의 상향류식 여과기는 모래에 의해서만 최종처리수에 잔존하는 부유물을 제거하는 것이어서 부유미립자, 색도, 악취, 잔여응집제 키타 오염물질 등에 의해 처리효율이 떨어져 최종처리수의 재활용이 적을 뿐만 아니라, 방류에 따른 하천수의 수질오염을 초래하게 되는 문제점을 가지고 있고, 모래에 부착된 부유물을 공기 및 세정기의 주름관을 통과할때 발생하는 충격에 의해서만 모래에 부착된 부유물이 분리되는 것이어서 응집제와 더불어모래에 부착된 부유물의 효율적 분리가 이루어지지 못함은 물론 응집제에 의한 부유물 누적에 따른 모래의 여과기능 상실이 촉진되어지는 단점을 가지고 있다.As described above, the conventional upflow filter for purifying the final treated water while continuously circulating the sand in the treatment tank to remove the suspended matter attached to the sand is to remove the suspended matter remaining in the final treated water only by the sand, so that the fine particles, The treatment efficiency is reduced due to color, odor, residual coagulant, and other contaminants, and there is less recycling of the final treated water, and it causes water pollution of the river water due to discharge. The suspended matter attached to the sand is separated only by the impact generated when passing through the corrugated pipe, so that the flocculant and the suspended matter attached to the sand cannot be efficiently separated, and the sand filtration function is lost due to the accumulation of the suspended matter by the flocculant. It has the disadvantage of being promoted.
상기와 같은 종래 상,향류식 여과기의 단점을 해소하기 위하여 개발된 본 발명은, 모래가 이송되는 사양관에 오존발생기에서 발생된 오존을 에어콤프레셔에 의해 공급되는 공기에 의해 공급시켜 모래에 부착된 부유물을 차1로 산화분해시킴과 동시에 양사관상에 설치된 초음파 발생기에서 조사된 음파에 의해 일어나는 진동 교란탈지 유화작용에 의하여 모래에 부착된 난분해성물질(응집제 및 유분)을 2차분리시키며, 모래세정부의 주름관으로 위치하는 초음파 발생봉에서 조사되는 음파에 의해 일어나는 진동 교란탈지 유화작용에 의하여 모래에 부착된 응집제 및 부유물을 최종적으로 분리 제거할 수 있게 한 것으로, 최종처리수를 여과시키는 모래로 부착된 각종 부유물질 및 응집제의 분리 효율을 높여줌으로서 여과처리수의 수질을향상시킴과 동시에 수질 향상으로 여과처리수의 재활용 범위를 넓힐수 있고, 모래로 부착되는 응집제 및 부유물을 완전하게 제거하므로서 부유물 및 응집제 부착누적으로 발생될 수 있는 모래의 여과기능의 상실을 방지할 수 있는 초음파 발생기를 이용한 상향류식 여과기를 제공하는데 그 목적이 있다.The present invention was developed in order to solve the disadvantages of the conventional phase, countercurrent filter, the ozone generated in the ozone generator to the specification pipe to which sand is transported by the air supplied by the air compressor attached to the sand Oxidatively decomposes the suspended matter firstly and at the same time secondary separation of the hard-decomposable substances (coagulants and oil) adhered to the sand by vibrating disturbance degreasing emulsification caused by the sound waves irradiated from the ultrasonic generator installed on both pipes. It is possible to finally separate and remove flocculant and suspended matter attached to sand by vibrating disturbance degreasing emulsification caused by sound waves irradiated from the ultrasonic generating rod located in the corrugated pipe of the government. It improves the water quality of the filtered water by increasing the separation efficiency of various suspended solids and flocculant. Ultrasonic generator that can extend the recycling range of the filtered water by improving the water quality and prevent the loss of sand filtration function that can occur due to the accumulation of flocculant and flocculant by completely removing flocculant and flocculant adhering to sand. The purpose is to provide an upflow filter using.

이하 본 발명의 바람직한 실시예를 명세서에 첨부된 도면을 참조하여 보다 상세하게 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도1은 본 발명에 따른 초음파를 이용한 상향류식 여과기의 단면 구성도 이다.1 is a cross-sectional view of an upflow filter using ultrasonic waves according to the present invention.
도시된 바와 같이, 본 발명의 상향류식 여과기의 원수라인(13)에 폐수처리장치에서 전처리된 최종처리수가 응집과정을 거쳐 유입되어서 부상하게 된다.As shown, the final treated water pre-treated in the wastewater treatment device to the raw water line 13 of the upflow filter of the present invention is introduced through the flocculation process to rise.
상기와 같이 부상하는 최종처리수는 처리조(10)로 충진되어진 모래를 통과하면서 최종처리수에 혼합되어 있는 부유물과 응집제가 모래에 의해 제거되어 진다.As the above-mentioned final treatment water passes through the sand filled in the treatment tank 10, the suspended solids and flocculant mixed in the final treatment water are removed by the sand.
모래를 거치면서 정화되어진 여과처리수는 처리조(10)의 상부로 설치되어 있는 방류수배출관(17)을 통해 방류되어 진다.The filtered water purified through the sand is discharged through the discharge water discharge pipe 17 installed above the treatment tank 10.
상기에서와 같이 최종처리수에 혼합되어 있는 부유물을 제거 정화시킨 모래에는 잔여 응집제와 부유물이 부착되어져서 오염되어지게 되는데, 오염된 모래는 사갓형 경사판(12)의 하부로 위치한 모래수집장치(11)로 모여 펌핑되어 사양관(13)을 따라 이송된다.As described above, residual flocculants and suspended solids are attached to the sand to remove the suspended solids mixed in the final treated water, and the contaminated sand is contaminated by the sand collecting device 11 located below the swash plate 12. Gathered and pumped and transported along the specification pipe (13).
상기와 같이 양사관(13)을 따라 이송되는 모래의 부유물은 오존발생기(20)에서 발생되어 에어콤프레셔(21)의 공기와 함께 양사관(13)으로 공급되는 오존에 의해 산화 분해되어지게 되고, 오존에 의해 모래에 부착되어진 잔여 응집제 및 부유물이 1차 분리되어진 모래는 양사관(13)으로 설치되어진 초음파 발생기(30)를 지나면서 잔여 응집제 및 부유물이 2차 제거되어지게 된다.As described above, the floating matter of sand transported along the pipes 13 is oxidized and decomposed by ozone generated by the ozone generator 20 and supplied to the pipes 13 together with the air of the air compressor 21. The sand from which the residual flocculant and the suspended matter adhered to the sand by ozone is separated from the residual coagulant and the suspended matter by passing through the ultrasonic generator 30 installed in the pipes 13.
응집제 및 부유물을 2차 제거하는 초음파 발생기(30)는 모래에 음파를 조사하게 되고, 음파는 거대한 펄스에너지를 생성시켜 모래에 거대한 압력과 온도의 급격한 상승을 일으켜 모래에 부착되어 있는 잔여 응집제 및 부유물의 분리를 일으킴과 동시에 음파는 에너지원으로 작용하여 진공의 공동현상이 발생하여 엄청난 충격및 압력이 발생되어지며, 강력한 기계적교란(케비네이션, 공동현상)을 일으켜 잔여 응집제 및 부유물을 탈지 유화시키게 된다.Ultrasonic generator 30 for secondary removal of flocculant and suspended solids irradiates sound waves to sand, and the sound waves generate enormous pulse energy to cause a huge rise in pressure and temperature in the sand resulting in the remaining flocculant and suspended solids attached to the sand. At the same time, the sound waves act as an energy source, causing vacuum cavitation to generate tremendous shocks and pressures, and causing strong mechanical disturbances (cavitations, cavitation) to degrease the remaining coagulants and suspended solids. .
