摘　　要：通过湿地生态修复工程的构建，对天津经济技术开发区高含盐再生水景观河道水体氮磷去除效果进行研究。结果表明湿地生态修复工程对氮磷具有较高的去除率，TN、NO3^--N、NH4^4-N和TP、PO4-P的去除率分别为：66．90％、76．72％、3．98％、68．22％、79．31％；水体中全盐量（TDS）浓度在4891~4796mg／L范围内变化，说明河道洗盐基本结束；整个河道植物生长茂盛，生物量倍增，没有出现受盐胁迫的现象。Nitrogen and Phosphorous removal effect of highly salty reuse water by constructed wetland eco- restoring project in Tianjin Economic-Technological Development Area （TEDA） Landscape River. The results show that it is obviously of purification effects while the rate of removal Nitrogen ＆ Phosphorous is very high with constructed eco-restoring project. The rate of TN, NO3^--N, NH4^＋ -N, TP and PO4-P respectively is 66. 90%, 76.72%, 3. 98%, 68. 22 %, 79. 31%; Concentration of total dissolved salty varies from 4891 to 4796 mg/L and this indicate that salty has been finished in water. Plants grow very well and their quantities of life-forms are multi-augment. TDS does not affect the growth of vegetables.
