| 摘 要： | 通过对比标准型、深型及浅型毛细管这三种不同构造的地下土壤渗滤沟去除模拟农村生活污水氮磷的效率,讨论了渗滤沟构造对氮磷去除效果的影响。结果表明,三种渗滤沟对氨氮、总氮和总磷的去除率均分别可达95%、80%、90%以上。毛细管型构造渗滤沟在布水均匀性、稳定性及氮、磷去除效果等方面均优于标准型构造的渗滤沟。

| Abstract: | Three types of infiltration trenches including capillary and typical were studied to assess the influence of technical construction of trench on nitrogen and phosphorus removal from countryside sewage, and results showed that removal efficiency of NH3-N, total nitrogen and total phosphorus in the system were above 95%, 80% and 90% respectively. Capillary infiltration trench was comparably superior to typical infiltration trench in the stability and removal efficiency. |
