摘　　要：为了最大程度地改善深圳市布吉河水质状况,在先期进行布吉污水处理厂中试试验的基础上,建设了小型人工湿地,深度处理污水处理厂二级出水,探讨污水处理厂二级出水在人工湿地基础上的改善程度,为该市布吉污水处理厂建设完成后是否规划建设景观湿地提供参考依据。结果表明:人工湿地对二级出水的COD、NH3-N、TN、TP等重要控制指标均有比较明显的深度处理作用;夏季的运行效果总体上比秋、冬季处理效果好,季节变化对TN去除率的影响最为明显,但对出水COD、NH3-N、TP指标影响相对较小。In order to improve the water quality of the Buji River in Shenzhen, and on the basis of earlier larger-scale experiments at the Buji Sewage Plant,a small-scale constructed wetland was constructed for advanced treatment of secondary effluent from the sewage plant.The improvement after advanced treatment of the secondary effluent by a constructed wetland was studied,providing a reference for whether the construction of a wetland should be planned after the construction of the Buji Sewage Plant is completed.The experimental results indicated that the constructed wetland had a quite significant advanced treatment effect on important water quality indexes such as COD,NH4^＋-N,TN,and TP of secondary effluent.The treatment effect was generally better in the summer than in the autumn and winter.The seasonal variation affected the removal rate of TN more significantly than that of COD,NH4^＋-N,and TP.
