Understanding the role of vegetation in nitrogen removal by biofiltration

由于过量的氮负荷，特别是来自城市雨水的氮负荷，澳大利亚的许多海湾和水道都受到了富营养化的威胁。生物过滤系统被广泛使用(仅墨尔本水务公司就计划在未来5年内与市政当局合作建设10000个系统)和潜在的有效处理，但它们的脱氮高度依赖于所使用的植被类型。该项目将加深对植被在雨水生物滤池固氮中的作用的了解，从而为生物过滤的植物选择和设计提供重要的指导。

Many of Australia's bays and waterways are threatened by eutrophication due to excess nitrogen loads, particularly from urban stormwater. Biofiltration systems are a widely used (Melbourne Water alone has a programme of constructing 10000 systems in partnership with municipalities over the next 5 years) and potentially effective treatment, but their nitrogen removal is highly dependent on the type of vegetation used. This project will improve the understanding of the role of vegetation in nitrogen retention by stormwater biofilters, and will thus provide important guidance on plant selection and design for biofiltration.
