산업의 고도화와 인구 도심화에 따라 도시 하수처리장과 공단 및 농공단지 폐수처리장에서 처리하고 있으며, 이들 처리장 등에서는 오폐수 처리과정에서 다량의 슬러지가 발생한다. 현재까지는 발생되는 대부분의 슬러지를 해양투기, 매립 그리고 소각 등의 방법으로 처리하고 있으나, 해양투기 및 매립과 같은 슬러지 처분 방법은 지가의 상승, 침출수 발생, 환경오염 유발, 지역주민과의 갈등뿐만 아니라 런던 협약의 "슬러지 해양 투기 및 매립금지" 규약에도 위배되는 문제점을 안고 있다.In accordance with the advancement of the industry and the urbanization of the population, the city sewage treatment plants, industrial complexes and agricultural industrial wastewater treatment plants are treated, and large amounts of sludge are generated in the wastewater treatment processes. Until now, most of the sludge generated is treated by ocean dumping, landfilling, and incineration.However, sludge disposal methods such as dumping and landfilling are not only rising land prices, leachate generation, environmental pollution, and conflict with local residents. There is also a violation of the London Convention on "Sludge Offshore Dumping and Reclamation".
한편 퇴비, 아스팔트 충진재, 경량골재, 시멘트 원료 등과 같은 자원화로 이용하는 방법을 통해 슬러지를 재활용하여 최종 발생 슬러지 량을 최소화하는 연구들이 활발히 진행되고 있지만 슬러지 자원화 및 최적의 매립효과를 얻기 위한 필수조건인 슬러지의 함수율 저하 기술의 둔화로 슬러지의 효율적인 처리가 어려운 실정이다.On the other hand, studies are being actively conducted to minimize the amount of sludge generated by recycling sludge through the use of resources such as compost, asphalt filler, lightweight aggregate, and cement raw material, but sludge, which is an essential condition for sludge recycling and optimal landfill effect, is being actively researched. Due to the slowing down of the water content reduction technology, the efficient treatment of sludge is difficult.
슬러지에서 수분 함량을 낮추기 위해서 다양한 구성의 탈수기를 사용하고 있으며, 근자에는 탈수기를 통해서 1차 탈수한 85%대의 높은 수분을 함유한 슬러지케이크를 다른 방식의 탈수기를 이용하여 2차 탈수하여 함수율을 60~40%대로 낮추는 기술이 사용되고 있다.In order to lower the water content in the sludge, various dehydrators are used, and in recent years, the sludge cake containing 85% of high water, which was first dehydrated through the dehydrator, was dehydrated using a different type of dehydrator to make the moisture content 60 The technology of lowering to 40% is used.
그러나 종래 알려진 탈수장치들의 경우 대부분 필터 내부에 슬러지를 투입한 후 기계적 혹은 화학적인 압력을 가하면서 탈수하여 함수율을 저감시키는 구성으로 함수율을 50% 이하로 낮추는데 많은 어려움이 있었다.However, most of the known dewatering devices have a lot of difficulties in reducing the water content to 50% or less as a configuration in which sludge is introduced into the filter and then dehydrated while applying mechanical or chemical pressure.
이에 본 발명에서는 상기한 종래 폐수슬러지 탈수 건조장치의 제반 문제점을 해소코자 본 발명을 연구 개발한 것으로서, 본 발명에서는 본 발명자가 선출원한 슬러지 분배 공급장치(10-2009-0136142)를 통해서 공급되는 1차 탈수된 폐수슬러지를 병렬로 설치되는 2개 이상의 고온발열롤러 표면과 연속적으로 접하도록 2장의 여과벨트를 설치하여 여과벨트 사이로 공급 이동하는 슬러지를 가압 건조할 수 있게 함으로 해서 탈수 및 건조 효율성을 향상을 기대할 수 있고 대량의 슬러지를 연속적으로 처리할 수 있는 높은 처리능력을 제공할 수 있는 폐수슬러지 처리용 탈수 건조장치를 제공함에 발명의 기술적 과제를 두고 본 발명을 완성한 것이다.In the present invention, to solve the above problems of the conventional wastewater sludge dehydration drying apparatus as described above, the present invention has been researched and developed, and in the present invention, the present invention is supplied through a sludge distribution supply device (10-2009-0136142) pre- filed by the present inventors.
