Bioenhancement of NAPL pool dissolution: experimental evaluation

摘要

Experiments were conducted to quantify nonaqueous phase liquid(NAPL)pool dissolution and its enhancement by in situ biodegradation. The experiments were performance using square cross-section, glass-bead packed column reactors with a small pool of a toluene-in-doecane mixture(toluene mole fraction, X_tol≈0.02 or 0.09). experimental quasi-steady-state toluene dissolution fluxes were de- termined using a ~14C-carbon mass-balance approach during water flushing with and without bio- degradation.
