Self-purification mechanism and empirical analysis of pollutants in rivers
By appropriate assumption and simplification, the law of the movement and dispersion with water and the attenuation and transformation of pollutants in rivers is described, with mathematical models given respectively, based on which, the one-dimensional mathematical equation of pollutants in rivers is obtained, the turbulence self-purification model of pollutants in rivers is discussed, and finally the example is given.
