The Research about Prediction of Environment Impact of Ethylene Project on Groundwater

This paper takes Wuhanpsilas "800ths tons ethylene project" as an example. According to the involved model parameters, which are obtained from the saturated soil column test of one-dimensional infiltration, and the law of the pollutant concentration in soil column from sewerage leaching experiment, the basic equation of contaminant transport in the porous soil was established, and then, we have predicted and evaluated the vertical leakage time of the contaminant from surface to the underlying aquifer. The impact of the project on groundwater environment with HYDRUS1D was predicted, and the ranges were divided by different polluted extent. Finally, we put forward some measurements and tactics, to prevent the pollutants from leaking downward.
