摘　　要：通过粉煤灰与芦苇构建的模拟人工湿地系统处理城市污水的试验研究，结果表明：该系统对N、P具有较好的去除效果。其对化粪池出水中NH4^＋-N和TP的去除率分别为74．8％～84．4％、79．1％～89．7％。本试验为建立一种低成本、多效益的废水良性生态处理系统以及为平顶山市粉煤灰的资源化利用提供一条新途径。An experimental study of municipal sewage by way of simulation artificial wetland system constructed by fly ash and reed has been made. The experimental result shows that this system has better removal results to N, P. It is 74.8% - 84.4%, 79. 1 % - 89. 7 % of respective removal rate of NH4^＋ -N and TP in the septic tank. This experiment sets up a benign ecological process system for waste water with low cost, more benefit, which offers a new way for recycle treatment of fly ash in Pingdigshan city.
