| 摘 要： | 提出了城市生态河道工程构建的技术方法，并研究了示范工程对城市污水处理厂出水的深度净化规律。实验结果表明，在保证生态景观功能的前提下，将生态河道技术工艺用于污水处理厂出水的深度净化，能够高效、稳定地去除氮磷等营养物，河道出水可以满足城市景观水体补充水源的水质要求，出水TP、PO3-4、TN、NH3-N和NO3-N平均值分别达到0.263、0.116、2.570、0.752和2.438 mg/L，去除率分别达到85.4%、92.8%、60.8%、39.7%和77.2%。

| Abstract: | The technical methods for urban ecological river construction are proposed,and the advanced purification of the secondarily-treated WWTP effluent in a full-scale demonstration project is studied.It is shown that ecological-engineered urban river can be used for tertiary treatment of WWTP effluent with high and stable nutrients removal efficiencies when keeping its landscape function.The treated effluent can meet the water quality standards for scenic environmental use,the average concentrations of TP,PO3-4,... |
