摘　　要：针对传统无砾石管式地下渗滤系统存在的处理性能差,渗滤通量低两个问题,通过去掉包裹织物,提高渗滤管开孔率、改变开孔方式,设计了无砾石微孔管地下渗滤系统。通过实验研究表明,无砾石微孔管地下渗滤系统对COD、氨氮的去除率比传统管式系统分别提高了10.8%、12.7%,总磷去除率并无显著差异,ORP值提高约85mV,渗滤通量提高26.8%。无砾石微孔管地下渗滤系统和传统管式地下渗滤系统对COD、氨氮在土壤中的降解趋势线存在明显的差异,而对磷的去除过程几乎完全相同。In order to solve the problems of poor processing performance and low flux of the traditional gravel - less pipe leach fields（ TGPLF）, gravel -less perforated pipe leach fields（GPPLF） were designed, by removing the fabric out-side the pipe, enhancing the pipe＇ s openings rate and changing the distribution of the holes on the tube wall of the TGPLF Studies showed through experiments, the removal efficiency to COD and ammonia nitrogen in GPPLF increased by 10. 8% and 12. 7%, respectively, relative to the TGPLF, total phosphorus removal efficiency was not significantly different, ORP value increased by about 85mV, flux increased by 26. 8%. The COD, ammonia nitrogen degradation trend lines in the soil were obvious different between GPPLF and TGPLF, while the removal process of phosphorus almost identical.
