The article presents the algorithm for solving nonlinear partial differential equations, that describe the process of air contamination. The algorithm is based on an appropriate modification of the grid method. Boundary conditions and border values are considered, and a difference scheme construction method is proposed. As a result, problem is degenerated in two-dimensional one, and reliable algorithms for its solution are developed and approved.
