摘　　要：在国内首次提出将人工湿地技术用于污水厂剩余污泥的脱水与稳定,进行了实验研究。考察人工湿地的性能,确定最佳工艺。经处理后TN去除率为57.85%;TP去除率为44.03%;COD去除率为78.09%;污泥的体积降低了92.6%。研究结果表明,该技术有效地对剩余污泥进行脱水,从而达到污泥稳定的目的。The artificial wetland technique proposed firstly was applied for dewatering and stabilities of ex- cess activated sludge in the experiment. The artificial wetland performance was examined to determine the opti- mum process. After treated, the removal rates of total nitrogen, total phosphorus and COD were 57. 85% , 44.03% and 78.09% , respectively. The results show that this technique is effective for dehydration of excess activated sludge and sludge stabilization.
