抄録

Removal efficiencies of Simazin, Fenitrothion, Napropamid, and tetrachloroethylene, PCE, from synthetic wastewater by the multi-soil-layering, MSL, method were studied. Volcanic ash soil (<i>Kuroboku</i>) was generally more effective than sandy soil (<i>Masa</i>) for removal of pesticides. Fenitrothion could be effectively removed by even sandy soil only or zeolite only. Addition of 2 weight % of activated carbon to an MSL system using volcanic ash soil significantly improved its performance for Simazin, Napropamid and PCE removal. Removal efficiencies of the above-mentioned toxic chemicals from wastewater containing mean concentrations (<i>μ</i>g·<i>l</i><sup>-1</sup>) of 350 for Simazin, 800-1300 for Fenitrothion, 2000-3500 for Napropamid, and 140 for PCE were 73-100%, 95-97%, 71-100%, and 95-99%, respectively, at their steady state with the loading rates of 270-400 l·m<sup>-2</sup>·day<sup>-1</sup>. In terms of PCE removal, an MSL system using sandy soil with the addition of metal iron also showed a high removal efficiency of more than 90%. In this MSL system and that with added activated carbon at the rate of 0.2 weight %, PCE was removed not only by sorption but also by degradation. Chemical degradation by metal iron added to the MSL system and biodegradation of PCE into TCE and cis-1,2DCE seemed to occur simultaneously.
