| 摘 要： | 为了探讨天津滨海泰达生态景观河道对污水处理厂出水深度净化的效果,2009年对该河道水体进行监测分析,结果表明该河道对氮、磷营养盐具有良好的可持续净化能力,河道出水达到景观环境用水的再生水水质标准,出水TN、NH3-N、TP和PO43-平均浓度分别为1.49mg/L、0.75mg/L、0.16mg/L和0.01mg/L,相应去除率分别达到93.38%、41.13%、88.09%和98.16%;沿程水体COD和TDS变化规律不明显,去除效果不理想;河道中端与出水端水体水质相近,建议在今后相似工程中可以适当提高河道式湿地的水力负荷。

| Abstract: | To study the advanced purification effect of secondarily-treated WWTP effluent by TEDA ecological scenic watercourse in coastal area,the water was monitored in 2009.The monitoring data showed that the ecological scenic watercourse took a good and sustainable role in purifying secondarily-treated WWTP effluent.For this river-type wetland,the effluent water quality reached the Reuse of Urban Recycling Water-Water Quality Standard for Scenic Environment Use(GB/T 18921-2002),with average concentrations of TN,NH... |
