【 摘 要 】

In this paper, the numerical solution of concentration convection-diffusion equation is applied to the selection of emergency treatment schemes for water pollution, and the corresponding high-precision difference schemes are proposed. On this basis, taking the emergency treatment of oil spill in rivers as an example, the oil fence and the oil receiving device are corresponded to the first and second moving boundaries respectively. Four kinds of comparison schemes are given. Through numerical simulation of high-precision format, the time when oil spill is cleaned up in water area is obtained, and the efficient treatment scheme under the same parameters is selected. . The results show that the numerical simulation method presented in this paper is reasonable and reliable, and provides a quick and accurate solution case for the selection of emergency treatment schemes for water pollution.
