摘　　要：利用粉煤灰与水生植物复合构成一种新型人工湿地系统，并实验研究了其对生活污水的净化功能。结果表明：系统对ＣＯＤ，ＳＳ，ＮＨ４－Ｎ，Ｔ－Ｐ均具有良好的去除效果。该系统的建立提供了一种低成本、多效益的废水良性生态处理系统，并为粉煤灰的大量应用开辟了一条新途径。Based on principle of environmental system engineering, the constructed wetland using fly ash assubstrata was constructed. Experiments were carried out to study its sewage treatment performance. The resultsindicated that the system could efficiently remove COD, NH_4-N, T-P. So well it provided a low-cost and multibenefit ecological system fir wastewater treatment and developed a new way for application of fly ash.
