하수처리장 방류수 유입 인공습지를 통한 탄소 저장량 산정 = Estimation of carbon storage through constructed wetland operated with STP effluent

다국어 초록 (Multilingual Abstract)

As greenhouse gas emissions have caused severe climate change, numerous problems have occurred. Among greenhouse gases, the study focused on CO2, especially carbon, and tried to store carbon through and tried to store carbon through constructed wetland. The study tried to measure the total amount of carbon and separate the total carbon into two types, soil organic carbon (SOC) and plant biomass. The constructed wetland has two types of modules, one is a vertical flow surface wetland (VFS) and the other is a horizontal flow surface wetland (HFS). This study planted Typha orientali C. on the vertical flow wetland and Phragmite australis on the horizontal flow wetland. To store carbon, this study inflowed effluent from sewage treatment plant into the constructed wetland (CW). During the operation days, the amount of soil carbon and vegetation carbon storage was measured from the constructed wetland. This study has the purpose of seeking much more effective constructed wetland with carbon storage, researching the previous study on biomass, and adapting the result to SOC from the constructed wetland. Planting Typha orientali C. on the vertical flow wetland and Phragmite australis on the horizontal flow wetland, carbon storage of each wetland had 25.57 kg/ha/yr and 29.53 kg/ha/yr. Yet, in VFW carbon storage more effective with Sedum takeminese. Since the constructed wetland was operated by effluent from sewage treatment plant, to operate the wetland with ease, undergroundization sewage treatment plants in Korea, apply the most effective constructed wetland on the land where sewage treatment plants were located then 64,937ton/ha of carbon could be stored per year.
