摘要: This study investigated the potential of using a mixture fishpond bund material, completely decomposed granite and river sand as substrate in constructed wetland for phosphorus removal. Core samples were collected from newly Hong Kong Wetland Park (HKWP) receiving influent stormwater nearby new town, batch incubation experiments conducted to determine P sorption characteristics sediments. The HKWP sediments adsorbed majority available initial 20 min incubation, with first-order rate constant 1.01–2.11 h −1 . Sediments reedbeds freshwater marshes possessed great capacity adsorption high Langmuir
