제주도 하수처리장 방류수를 이용한 소수력 발전에 대한 연구 = Micro Hydropower Generation by Discharge Water of Sewage Treatment Plant in Jejudo

다국어 초록 (Multilingual Abstract)

This study is to investigate the micro hydropower by discharge water of Jeju sewage treatment plant located in Jeju city and Dongbu sewage treatment plant located in Seogwipo city, Jejudo. The flow rate is applied at 1.11m³/sec in Jeju and 0.157m³/sec in Dongbu, which are the average 95 day flow rated for the recent 3 years. The net head is 5.21m in Jeju and 12.41m in Dongbu which are hight between discharge flow chamber and the location of hydraulic turbine installation. Therefore, the quantitiy of electric of power generation is estimated to be 42.97kW in Jeju and 14.6kW in Dongbu. The monthly quantity of electric generation is 28.23MW in Jeju and 9.46MW in Dongbu. Also the yearly quantity of electric generation is 338.7MW in Jeju and 113.53MW in Dongbu. The type of hydraulic turbine recommends a crossflow or a tubular in Jeju and an inline-type hydraulic turbine in Dongbu.
