  • 본 발명은 약품 혼합조와 침전조 일체형 초고속침전 수처리 장치 및 이를 이용한 수처리 방법에 관한 것으로서, 일반적인 수처리 공정에서 필요한 각각의 다수의 단위 공정들을 단일 처리조 내에서 수행하게 함으로써 약품혼합, 응집반응, 침전, 슬러지 인출 및 처리수의 배수가 시간 간격을 두어 이루어지도록 하여 전체적인 유체의 체류시간이 줄여 최대 30분 이내의 초고속 수처리가 가능하도록 하는 효과를 갖는다. 또한, 약품 혼합조, 반응조 및 침전조를 별도로 구성하지 않고 단일 처리조로 시설을 컴팩트화하여 시설비 및 소요 부지를 줄일 수 있도록 함과 아울러 처리수의 수질을 SS(Suspended Solids) 기준으로 1ppm 이하로 만족시킴으로써 후단의 여과공정이 불필요하여 시설비를 절감할 수 있는 효과를 갖는다. 또한, pH 감지부에 별도의 pH 지시계 세척부를 설치하여 안정적으로 pH 감지가 이루어지도록 하여 약품 주입을 경제적이고 효율적으로 이루어질 수 있도록 하여 수처리에 따른 유지 및 관리 비용을 절감시킬 수 있도록 하는 효과를 갖는다.

  • A physicochemical process called ultra rapid coagulation(URC) was applied as a pilot scale to recover eutrophicated lake water at Inkyung Lake located on-campus in Inha university. The URC was uniquely designed to completely remove the presence of phosphorus up to 95%, which in turn leading to lessen the level of eutrophication of lake. For a pilot test of period, the lake was restored showing Carlson's Trophic State Index(TSI) of mesotrophic state which accounts for the reduction of total phosphorus and chlorophyll-a down to approximately 55 from 70 and 73, respectively. A residual presence of aluminum and additional coagulants in the effluent was tested for their potential effects on Photobacterium phosphoreum. The effect concentration ($EC_{50}$-15 min) observed in the effluent revealed that the bioactivity of Photobacterium phosphoreum was not influenced by the residual presence of coagulants. After the pilot test of period, the lake was consequently restored as a mesotrophic state in obtaining the second grade of lake water quality. The URC may be further applied for restoration of greater scale of lake in eutrophication.

  • Ultra Rapid Coagulation (URC) can dramatically remove pollutants loaded in wastewater by adding weighted coagulation additives (WCA) and recycling sludge into the coagulation basin to increase settling velocity and surface adsorption ability of floc. Also settling chamber together with lamella plates offers the high rate settling velocity, which can economically treat a considerable amount of pollutants like as combined sewage overflow (CSO) during the heavy rainfall and reduce the pollutants load into the receiving water for securing water source. It was estimated optimal configuration of settling chamber by using fluent model and the possibilities of reusing the sludge generated in this system.

  • A physicochemical process called Ultra Rapid Coagulation(URC) can dramatically remove organics, metals, and phosphates in wastewater by adding weighted coagulation additive(WCA) and recycling sludge into the coagulation basin to increase the growth rate and adsorption ability of floc. Also this process can improve floc settling rate than conventional coagulation process and reduce the pollutants loaded into the receiving water for securing water source. It was evaluated that WCA and sludge added have effects on the removal efficiency and estimated the possibilities of reusing the effluent from this process.
