Abstract
This research was performed to evaluate the effectiveness of one- and dual-stage recycled-water systems in slurrybioreactor treatment for coal tar-contaminated soil. Silty loam soil was used for this research. Coal tar and 14 targetPAHs (Polycyclic Aromatic Hydrocarbons) concentration in the soil were determined with gas chromatography. Therewas no significant difference between removal efficiencies of one- and dual-stage recycled water systems in case ofabout 4,000 mg coar tar/kg. However, the dual-stage system increased significantly the removal efficiency in case ofabout 20,000 mg coar tar/kg and the first-order kinetic constant of the system was over 1.5 times higher than that ofone-stage recycled water system. 3-Ring compounds in PAHs was removed completely within 30 days of operation.Coar tar was removed in over 96% through biodegradation and removed in about 4% by evaporation. High correlationcoefficient (r2 = 0.91) was found between water solubility and removal efficiency of the cyclic compounds.
