    • A floating wetland raft comprising a floating raft body onto which is attached a biodegradable mat. The floating raft body is preferably made of closed cell polyethylene foam, and the mat may be woven of coir fiber. The mat covers the raft body and nests into an open area therein. The mat serves as a surface on which aquatic plants are grown for consuming nutrients from the water beneath. The biodegradable mat and associated plant biomass can be removed and subsequently replanted elsewhere or composted. The nutrients contained in the removed biomass represent a permanent reduction of nutrients in the water from whence they came. The floating raft body is durable and can be used repeatedly by attaching a freshly planted mat and repeating the nutrient removal process, which helps alleviate the problem of nutrient overloading in bodies of water.
    • 一个漂浮的湿地筏,包括浮筏体,其上附着有可生物降解的垫。 浮筏体优选由闭孔聚乙烯泡沫制成,并且垫可以是椰纤维纤维编织物。 垫子覆盖筏体并嵌入其中的开放区域。 该垫作为水生植物生长的表面,用于从下面的水中消耗营养物质。 可除去生物降解垫和相关植物生物量,随后将其重新种植在其他地方或堆肥。 去除的生物质中含有的营养物质代表着水中营养物质的永久性减少。 浮筏体是耐用的,可以通过连接新种植的垫子并重复营养物去除过程反复使用,这有助于减轻水体中营养物质超载的问题。
