摘　　要：通过3种植物——水葱、香蒲和美人蕉对天津经济技术开发（以下简称泰达）高含盐再生水景观河道水质净化效果进行研究，表明水力停留时间（HRT）对水体中污染物COD、TN、NH3-N、NO3 -N、TP、PO4-P的净化效果有明显的影响，各主要污染物去除率随HRT变化范围如下：COD的去除率14．47％～45．09％；TN的去除率为25．50％～71．00％、NH3-N的去除率为39．96％～82．47％、NO3-N的去除率为27．21％～74．41％、TP的去除率为38．91％～90．01％、PO4-P的去除率为38．55％-92．01％；水体中TDS含量在4500mg／L左右对植物及其水处理系统的净化效果没有影响；植物系统的出水pH均比进水的低．HRT相同，水葱、香蒲对磷的去除率较美人蕉高，其原因是因为水葱、香蒲是以湿地方式种植，而美人蕉是水培方式种植，前二者由于土壤的对磷吸附的等作用从而导致磷的去除率较后者高，3种植物对其它污染物去除率基本相．The effects of purification highly salty reuse water quality are studied by three plants-scirpus tabemaemontanii Gmel, Typha and Canna indica Linn in Tianjin-Economic and Technology Development Area Landscape River. The resuits show that hydraulic retention time has obviously influence on the effects of purification highly salty reuse water quality. Moreover, removal rates of all kinds of contamination vary with HRT, such as removal rate of COD, TN, NH3 - N, NO3-N, TP, PO4-P is 14.47 % -45.09% 25.50% -71.00% ,39.96% -82.47 %, 27.21% -74.41%, 38.91% -90.01%, 38.55% -92.01% respectively. Both the three plants grow and effects of purification of the highly salty reuse water treatment systems operate very well while concentration of TDS is about 4 500 mg/L in the water; pH of effluent water plants is lower than influent. Removal rates of Phosphorus by Scirpus tabernaemontanii Gmel and Typha are higher than its by Canna indica Linn when the HRT is sameness. The reason that Scirpus tabernaemontanii Gmel and Typha are planted with wetland while Canna indica Linn grows in water, at the same time phosphorus is removed from water because of the function of soil adsorption and so on. The rates of removal contaminations else are invariable by the three plants.
