Abstract: Due to the pollutants from lots of industry sewage and organic solvents, they arelow solubility in water and hard to decompose in nature, didn.t treated adequately, itwill cause the ground water pollution. In light of above description, this study adoptsDNAPL Simulator (Guarnaccia and Pinder,1997) to improve this problem.First, we apply the k-S-P relationship of experiments (Cheng,1997) to buildvirtual sand-box. Then exploring the impact of scaling rule on transport simulation ofDNAPLs. Initial water content and scaling rule will influence the simulative results,especially scaling rule. On the other hand, when Water-Gas phase pair is adopted, theerror between experiments and values following scaling rule is the smallest of threepairs(Gas-Water Gas-NAPL Water-NAPL phase pair) and the amount of DNAPLinto sand-box is the most of three pairs for DNAPL whenever hysteresis consideringor not. Consequently, Water-Gas phase pair is suit of transport simulation ofDNAPLs.
