Recently, a low-impact development (LID) technic such as a wetland has been proposed as a Nature-friendly process for reducing pollutants caused by livestock wastewater. Therefore, the Daphnia magna toxicity was analyzed for livestock wastewater samples, to determine if a wetland system would also be effective in reducing this ecotoxicity. In the present study, acute D. magna toxicity was not significantly dependent on the presence and type of reed, nor type of media. However, when treated with construction wetlands, ecotoxicities decreased as well as TN, TP and COD concentrations. Therefore, it is considered that a construction wetland system with bio reeds and bio-media as well as general reeds would be effective to reduce the ecotoxicity of livestock wastewater. To apply a wetland system as the subsequent treatment process to a livestock waste water treatment facility, it is necessary to perform an integrated evaluation such as treatment efficiency and the ecotoxicity test for various characteristics of livestock wastewater.
