In this study, we have investigated the effect of pollutants removal of a vertical multilevel soil infiltration (VMSI) system on municipal wastewater treatment. The VMSI was of 30cm*20cm*50cm column, in which combined stuffing consisted of soil, quartz sand, active carbon and scrap irons were packed. As a result, VMSI system exhibited excellent removal efficiency with 91.7% of COD, 98.4% of NH4+--N,...
Soil infiltration treatment was proved to be an effective and low-cost treatment technique for municipal wastewater in many areas. This system was intensified by combined stuffing (with zeolite, active carbon, sawdust and scrap iron) set for multilevel and named Vertical Multilevels Soil infiltration system (VMSI). Bench-scale soil column experiments were performed in laboratory to investigate effects...
