摘要 [目的]介绍了复合填料在观澜河清湖段高效垂直流人工湿地尾水深度处理工程中的应用。[方法]开发出一种新型的人工湿地复合填料,对废水中COD、BOD5、NH3-N和TP等指标进行连续18个月的监测分析,研究了该复合填料在人工湿地系统中对城镇污水处理厂尾水深度处理的效果。[结果]废水中COD、BOD5、NH3-N和TP的平均去除率分别为71.3%、72.5%、84.7%和77.5%,湿地出水水质达到《地表水环境质量标准》(GB3838-2002)中的Ⅲ类标准;计算得到COD、BOD5、NH3-N和TP的平均面积反应速率常数(KA)值分别为0.53、0.60、1.09和0.69 m/d。[结论]该复合填料在人工湿地深度处理城镇污水处理厂尾水工程中取得了理想的效果。 [Objective]The research aimed to introduce the application of composite substrate to constructed Wetland for advanced treatment of Tailwater from perpendicular lake Duan high-effect stream tailwater treatment plant [Method] A novel composite substrate was developed for constructed wetland,COD,BOD5,NH3-N and TP in effluent were monitored and analyzed for 18 months.The advanced treatment of tailwater form municipal wastewater treatment plant by constructed wetland was studied.[Result] The results showed that the removal efficiencies of COD,BOD5,NH3-N and TP were respectively 71.3%,72.5%,84.7% and 77.5%.The effluent quality would meet the classⅢ criteria in the Environmental Quality Standard for Surface Water(GB3838-2002).The average area rate constants(KA) for COD,BOD5,NH3-N and TP were 0.53,0.60,1.09 and 0.69 m / d,respectively.[Conclusion] The composite substrate was efficient for advanced treatment of tailwater from municipal wastewater treatment plant.
