초록

In order to develop constructed wetlands for treating hydroponic wastewater in greenhouse, actual constructed wetlands were used the obtained optimum condition in previous study, and the removal rate of pollutant in the water according to 4 kinds connection method of piping such as system A (UP-UP stream), system B (UP-DOWN system), system C (DOWN-UP stream) and system D (DOWN-DOWN stream) were investigated. Removal rate of biochemical oxygen demand (BOD), chemical oxygen demand (COD),suspended solids (SS), total nitrogen (T-N) and total phosphorus (T-P) by system A (UP-UP stream)connection method in actual constructed wetlands were slightly higher than other systems. At the system A,the removal rate of BOD, COD, SS, T-N and T-P were 88, 77, 94, 54 and 94%, respectively. Under different hydroponic wastewater loading, the removal rates of pollutants were higher in the order of 75 L m-2 day-1 ≒150 L m-2 day-1 ≧ 300 L m-2 day-1. Therefore, optimum connection method was system A for treating hydroponic wastewater in greenhouse.
