在植物床过滤沟中种植有用的陆生和水生植物，除了资源回收和美化功能外，还可以处理生活废水。我们以前报道过，种植纸莎草的沟渠最有效地从人工废水中去除Nand P。我们评估了植物床过滤沟处理富营养化池塘水的有效性，与人工废水不同，富营养化池塘水含有颗粒Nand P.实验沟种植了纸莎草、非洲金盏花、薄荷和不耐烦。这些植物能有效地去除人工废水中的氮和磷，可用于农村社区生产手工艺品、切花和观赏用途。对照沟不含植物（无植物沟）。池水以n6 ~ 0.9 g m-2 d-1、P 0.2 ~ 0.35 g m-2 d-1的负荷率连续向沟渠供水。
Abstract Cultivation of useful terrestrial and aquatic plant species in plant bed filter ditches enables to treat domestic wastewater in addition to resource recycling and amenity functions. We reported previously that a ditch planted with papyrus removed Nand P most effectively from artificial wastewater. We evaluated the effectiveness of plant bed filter ditches in the treatment of eutrophic pond water, which unlike artificial wastewater, contains particulate Nand P. Experimental ditches were planted with papyrus, African marigold, peppermint, and impatience. These plant species were effective in removing N and P from artificial wastewater and could be used by rural communities for the production of handicrafts, cut flowers, and ornamental purposes. The control ditch did not contain plants (plant-free ditch). Pond water was continuously supplied to the ditches at a loading rate of 0.6–0.9 g m-2 d-1 for Nand 0.2–0.35 g m-2 d-1 for P. In the plant-free ditch, particulate Nand P in the influent were remove...
