Abstract

Abstract:

Based on simulated experiment research, this paper discusses the main rules and effect factors of nitrobenzene's transport and fate in riverside groundwater field. And based on the data of the simulated experiment, the numerical model of nitrobenzene's migration and transformation in riverside groundwater field has been built. The simulated result has indicated that the adsorption capability of nitrobenzene transporting in silt medium is better than that in sand medium. The adsorption coefficients of silt medium and sand medium are 0.526 cm³/g and 0.123 cm³/g respectively. Moreover, nitrobenzene's biodegradation rate constants of silt medium and sand medium are 0.043 h^-1 and 0.002 h^-1 respectively. This study has indicated that the numerical simulated result of experiment is better, then it can be used in field simulation and forecast in the near further.

Key words: nitrobenzene, riverside groundwater field, migration and transformation, numerical simulation
