Bioremediation of diesel-contaminated soil using pilot-scale biopiles

摘要

Three pilot scale biopiles and a landfarm to treat diesel contaminated sandy loam soil were constructed, operated and monitored for 113 days. The effects of vermiculite addition, increased bulking agent addition and tillage compared to forced aeration on contaminant reduction were examined. Samples were taken twice a week. Parameters monitored included total petroleum hydrocarbon (TPH) and microorganism concentrations, moisture content, temperature and pH. A degradation of 90 to 94
