摘要: Abstract Constructed wetlands have been used to treat contaminants, including ammonia and nitrate, with varying degrees of success; however, no study has performed evaluate treatment performance a constructed wetland specifically designed promote biogeochemical conditions controlling nitrification denitrification. Therefore, this research aims improve the design treating using by targeting needed for A pilot-scale was meet targeted ranges dissolved oxygen concentration, hydrosoil redox potential, pH, alkalinity, organic carbon availability enhance Design features included aeration, sucrose, oyster shell addition. The decreased ammonia-N from ∼20 mg/L in inflow nondetectable levels (<0.1 mg/L) outflow during three four months. Measured biogeochemica...
