Study on the Law of Carbon Tetrachloride Migration in Groundwater System

Abstract

Carbon tetrachloride (CCl 4 ) has a lot of toxic effects on the human body. According to our survey, the pollution of carbon tetrachloride in groundwater in the eastern part of Jinan City is serious. In this study, 40 sampling points were selected in the study area of 100km 2 , and carbon tetrachloride was detected in all sampling. The highest sampling point concentration as high as 20.87μ g / L . The concentration of carbon tetrachloride detected in 40 sampling points ranged from 1.68 to 20.87 μ g / L, and most of them exceeded the standard value of 2 μ g / L. In order to control the carbon tetrachloride pollution, a solute transport model was established by GMS software to predict the carbon tetrachloride pollution in the study area in the next 15 years. The results show that the concentration of carbon tetrachloride in the groundwater system will decrease to a certain extent, but there is still a considerable distance from the national standard, and the pollutants have tendency to migrate to the southeast and northwest.
