Treatment Efficiency and Plant Growth of Early Stage of Pond-Wetland System at Estuary Lake

Treatment efficiency and plant growth of a combined Pond-Wetland system was investigated. The system is composed of primary and secondary ponds and six wetland cells. Reed and cattail were planted as vegetation of wetland cells. The removal rates of BOD, SS, T-N, and T-P were 40%, 41%, 30%, and 47% at the secondary pond, respectively. The system removal rates measured at the last wetland cell were 57%, 54%, 60%, and 68% for BOD, SS, T-N, and T-P, respectively.
