본 발명은 세차장등 자동차관련 사업장의 함유폐수와 유수 및 양돈장등 폐수의 전처리와 화학 응집침전 또는 활성오니법에 의한 침전물을 체류시간과 관계없이 고형물과 상등수로 분리시키는 장치와 2차처리의 고도처리 및 슬러그(SLUDGE)농축여과장이체 관한 것으로 상부에 설치되는 투과막과 여기에 부착되는 슬러그층을 통과하는 오염물질이 여과 및 흡착에 의해 정제되어 폐수를 단시간내에 처리하도록 된 투과막 및 슬러그층을 이용한 상향류식 급속 폐수처리장치 및 슬러그 처리장치를 제공하는데 있다.The present invention is a pretreatment of wastewater and wastewater, such as running water and pig farms, and sediment by chemical flocculation or activated sludge process in car-related workplaces such as car washes, and solidification and supernatant water of secondary treatment regardless of residence time. And a sludge concentrated filtration carrier, and a permeable membrane installed at the top and a contaminant passing through the slug layer attached thereto are purified by filtration and adsorption to treat the wastewater in a short time. The present invention provides an upflow rapid wastewater treatment device and a slug treatment device.

종래 응집침전에 의한 고액 분리시 프러그(FLOC) 형성지에서 도입된 폐수가 독립된 첨전조내에서 일정 시간이 경과하여야 고액분리가 이루어지므로 그 체류시간에 상응하는 용량의 침전지가 필요하고 약품투입의 영향 또는 슬러그인출의 여부에 침전 슬러그가 부상하여 처리수를 혼탁하게 하는 문제점이 있으며, 또 소규모의 처리장치에 있어서는 슬러지의 발생량이 소량이므로 대부분의 경우 침전지내에 장기 체류시키므로 유 도 양돈장등에 있어서 유기성, 고탁성폐수를 처리함에 있어서 전처리로 혐기성소화법, 부폐조법등을 이용하고 있으나 이를 설치키 위하여는 많은 공간과 시설비가 문제가 되고, 활성오니법에 의한 2차처리수도 분해하기 어려운 유기물이 처리되지 않는 문제점이 있다.When solid-liquid separation by flocculation sedimentation is performed, solid-liquid separation takes place after a certain period of time in an independent feeder, so that the sedimentation basin corresponding to the residence time is required. Alternatively, there is a problem in that sediment slug rises or becomes turbid in the treatment of slug withdrawal, and in a small treatment apparatus, the amount of sludge generated is small, so in most cases, it is long-term stay in the sedimentation basin. In treating turbid wastewater, anaerobic digestion and waste disposal methods are used as pretreatment, but there are many spaces and facility costs for installing them, and organic materials that are difficult to decompose secondary treatment water by activated sludge process are not treated. There is a problem.

한편, 종래의 처리장에서 슬러그처리는 응집침전된 슬러그를 농축조에 도입하여 24시간이상 농축한 후 탈수기로 이송하여 탈수처리해야하므로 발생하는 슬러그의 체류시간에 상응하는 크기의 농축조의 설비가 필요하며, 해체된 슬러그의 혼입으로 혼탁되어 있으므로 집수조등에 재 이송하여야 하는 문제점이 있었던 것이다.On the other hand, the slug treatment in the conventional treatment plant is to introduce a flocculation settled slug to the concentration tank to be concentrated for more than 24 hours and then transferred to a dehydrator to dehydration process, it is necessary to install a concentration tank of a size corresponding to the residence time of the slug generated, Since there is turbidity due to the mixing of the dismantled slug, there was a problem to be re-delivered to the sump.

본 발명은 상기와 같은 종래의 폐수 및 폐유처리의 결점을 감안 해결하기 위하여 단일 탱크내에서 프러그 형성 및 침전이 동시에 발생토록하고, 환류 상향하는 유체의 상부에 세목의 투과막을 설치하여 처리수만 통과 시키고 시간의 경과에 따라 투과막에 슬러지층을 형성시켜 응집침전시킨뒤 처리수중에 함유되어 있는 미세한 고형물을 슬러그층에 흡착 여과시킴으로서 처리시간의 단축 및 처리시설의 소형, 경량화 및 처리수질의 개선을 도모할 수 있도록 한 것이다.The present invention in order to solve the drawbacks of the conventional wastewater and waste oil treatment as described above to cause the formation and precipitation of plugs in a single tank at the same time, by installing a fine permeable membrane on the upper side of the fluid to reflux up and pass the treated water only As the sludge layer is formed on the permeable membrane as time passes, the precipitate is coagulated and precipitated, and the fine solids contained in the treated water are adsorbed and filtered on the slug layer to shorten the treatment time, improve the size and weight of the treatment facility, and improve the treated water quality. It is to be done.
