Abstract :
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, 81.0% of TN and 97.3% of TP. Moreover, the proportion of biological and abiological effects in pollutants removal was also investigated through different reactor, and abiological effect against organic removal was 53-62%. In a long-term performance, the VMSI system exhibited excellent ability and stability in pollutants removal.
