Description
본 발명은 하수처리장의 침전조에 관한 것으로, 더욱 상세하게는 침전조에 설치되어 하수의 부유물을 급속하게 침전시킬 수 있도록 된 부유물 침전장치에 관한 것이다.The present invention relates to a sedimentation tank of a sewage treatment plant, and more particularly, to a sediment sedimentation device which is installed in a sedimentation tank to rapidly precipitate sewage in sewage.
최근 국민소득의 증대와 더불어 식생활이나 생활수준이 향상됨에 따라 하수로 흘러보내는 각종 폐수가 증대되고 있고, 이러한 폐수는 하천이나 강, 호수를 크게 오염시키고 있으며, 이미 상수원으로 이용되고 있는 한강 상류 및 낙동강 오염이 사회문제화 되고 있다. 따라서 이의 제거를 위한 고도의 처리기술과 함께 대규모의 설비투자가 요구되고 있고, 이러한 대단위의 설비투자와 함께 복잡하고 숙련된 운전기술이 요구된다.Recently, with the increase of national income and the improvement of dietary and living standards, various wastewater flowing to sewage is increasing, and this wastewater greatly pollutes rivers, rivers, and lakes, and it is already used as a water source. Pollution is becoming a social issue. Therefore, a large amount of facility investment is required along with a high processing technology for its removal, and complex and skilled operation skills are required along with such a large-scale facility investment.
현재 하수처리에 가장 많이 적용되고 있는 표준활성슬럿지공정은 하수중에 포함된 모래나 협잡물을 제거하는 전처리공정과, 자연침강을 이용하여 하수중의 부유물질(Suspended Solid : SS)을 침강·제거하는 1차 처리공정과, 상기 1차처리공정에서의 상층수를 폭기조에 유입시켜 처리하는 2차 처리공정과, 상기 2차 처리공정을 통과한 유출수를 방류전에 소독하는 소독공정 및 상기 1차 처리공정과 2차 처리공정에서 발생되는 슬러지를 탈수하여 최종 처분시키는 슬러지 처리공정의 다섯 단계의 기본공정으로 구성되어 있다.The standard active sludge process currently applied to sewage treatment is the pretreatment process to remove sand or contaminants contained in sewage, and the sedimentation and removal of suspended solids (SS) using natural sedimentation. The secondary treatment step, the secondary treatment step of introducing the upper water from the primary treatment step into the aeration tank, and the disinfection step of disinfecting the effluent passing through the secondary treatment step before discharge and the primary treatment step; It consists of five basic steps of the sludge treatment process that dewatered and finally disposed of sludge generated in the secondary treatment process.
이와 같은 다섯 단계의 기본공정중 1차 처리공정이 이루어지는 침전조는 하수에 포함되어 있는 부유물을 가라앉히기 위한 것으로, 침전조의 크기 유속 및 하수가 머무는 시간 등에 따라 부유물의 침전효율이 달라지게 된다.The sedimentation tank in which the primary treatment process is performed in the five basic steps is to sink the suspended matter contained in the sewage, and the sedimentation efficiency of the suspended matter varies depending on the size flow rate of the sedimentation tank and the sewage retention time.
즉, 유속을 줄여 하수를 장시간 머물게 하면 부유물의 침전율을 높일 수 있으나 하수 처리량이 줄어들게 되고, 하수 처리량을 늘리기 위해 침전조를 대형화하게 되면 설비 제작에 따른 자본이 많이 소요되는 단점이 생긴다.That is, the sedimentation rate of the suspended solids can be increased by reducing the flow rate so that the sewage can be kept for a long time, but the sewage treatment volume is reduced, and the sedimentation tank is enlarged to increase the sewage treatment volume.
따라서 가장 바람직한 침전조는 설비크기가 작아 장소를 적게 차지하면서도 빠른 시간내에 하수에 함유되어 있는 부유물을 침전처리할 수 있는 침전조이며, 현재 이에 대해 많은 연구가 진행되고 있는 실정이다.Therefore, the most preferable sedimentation tank is a sedimentation tank capable of sedimentation of suspended solids contained in sewage within a short time while occupying a small place and having a small size.
이에 본 고안은 상기와 같은 제반 요구사항에 부응하기 위하여 안출된 것으로, 침전조 내부에 간단히 설치하여 부유물을 포집함으로서 빠른 시간내에 하수의 부유물을 침전 처리할 수 있도록 된 침전조의 부유물 처리장치를 제공함에 그 목적이 있다.The present invention has been devised to meet the above requirements, and by simply installing the inside of the sedimentation tank to collect the suspended solids in the sedimentation tank float treatment apparatus that is capable of sedimentation of the sewage floating in a short time. There is a purpose.
