A new method to determine the scale range of environmental damage caused by water pollution accidents

Recently, water pollution accidents have happened frequently and have caused serious environmental damage. The purpose of this study was to propose a new method to determine the scale range of environmental damage in water pollution events. In this study, taking Fen River in Shanxi Province as an example, a computer simulation system was used to simulate the diffusion and migration process of phenol at different concentrations, so as to determine the curve series of the scale range of environmental damage caused by the simulated water pollution event. At the same time, taking the incident of water pollution caused by phenol leakage in Jingle County as an example, the actual scale range of environmental damage was compared with the simulated scale range, so as to determine the error of the scale range of environmental damage. The results showed that the maximum error of the curve series of the scale range of environmental damage was 22.4%, and the minimum error was 7.5%, which indicated that the error of the scale range of environmental damage was small, and proved that this method of quantitatively determining the scale range of environmental damage had certain scientific nature.
