Книга: «Agricultural runoff treatment with phosphorus-retaining materials»
|
Производитель: "Неизвестный" Researchers have studied and implemented numerous methods to curb non-point phosphorus (P) losses during the past decades. To further reduce P losses from agriculture, current P abatement methods must be amended with additional techniques. One such technique involves the use of P-retaining materials as filters placed in ditches within agricultural areas. This study encompasses a set of laboratory, meso- and large-scale set-ups to identify potential P-retaining materials available in Finland. The laboratory studies investigated the P retention potential of fresh and weathered Ca-rich as well as Fe-rich materials in flow-through tests. The most promising material was further employed in meso- and large-scale filters. As the application of the material was scaled up, and influent P concentration declined, cumulative P retention decreased. The meso-scale experiment indicated that the P removal efficiency decreased also due to the presence of dissolved organic carbon in the influents. As...
