Abstract: Based on the lithological and hydrological characteristics at a typical petroleum contaminated site,and data collection and analysis of long-term observation and water pumping and dispersion experiments,a numerical model of groundwater flow and solute transport was developed and verified by a flow model.BTEX was used as the simulation factor,the convection-diffusion solute transport process in groundwater was simulated using MT3DMS module of GMS software,and the organic pollutant biodegradation process with the coexistence of a variety of mobile or immobile microorganisms in groundwater was simulated using RT3Dmodule of GMS software.The results showed that chemical reactions of biodegradation can decrease the peak values of contamination,and a large amount of aerobic microbes and denitrification exist in the study area,which suggested that in-situ bioremediation can be used to control petroleum pollution.
