摘　　要：本文以广东本地漂浮植物凤眼莲[Eichhorniacrassipes(Mart.)Solms]、水浮莲[Pistiastratiotes(Raf.)Merr.]和水龙[Ludwigiaadscendens(L.)Hara]为供试植物,以此及其相互组合共7种不同的植物配置方式与无植物的方式对城镇污水的处理进行了对照。试验表明,试验期间有植物的装置比无植物的装置去除COD、TP、TN及NH4+-N的能力强。在夏季两种或两种以上的水生漂浮植物组合对COD的去除率比单独一种植物去除COD的效率高;但在冬季,水龙去除COD效果最好,其大小与其他各种配置方式处理污水COD差异显著;漂浮植物在夏季试验期间NH4+-N去除率高达97%以上,冬季为凤眼莲去除NH4+-N效果好;夏季植物去除TN能力为各种组合比单独某一种植物去除能力强,冬季为单独生长的凤眼莲最好.冬季和夏季的各种植物系统的TP去除率分别为32%～64%及83.3%～89.0%;无论是夏季和冬季,漂浮植物均能有效地调节pH值在水质标准6～9范围内。In the paper was carried out the contrast test for urban sewage treatment with different configuating ways of seven plants and without plant, with Eichhornia crassipes （Mart.） Solms, Pistia stratiotes （Raf.） Merr and Ludwigia adscendes （L） Hara as the tested plants. It was showed that the device with plants had stronger ability to remove COD, TP, TN and NH4^＋-N than the device without plant during the test period; the COD removal rate by the combination of two or more aquatic floating plants was higher than that by single plant in summer, but in winter, COD removal rate by Ludwigia adscendens（L.） Hara was the highest, being obviously different from the other configurating ways; NH4^＋-N removal rate by floating plant was as high as over 97% during summer＇s test; NH4^＋-N removal rate by Eichhornia crassipes （Mart.） Solms was higher in winter; for the TN removal by summer＇s plants, various combinations had stronger removal ability than single plant; in winter, Eichhornia crassipes （Mart.） solms growing alone had the strongest removal ability; TP removal rates of various plant system in winter and summer were 32%-64%,and 83.3%-89.0% respectively; regardless of summer or winter, floating plant could adjust effectively pH within 6-9.
