【Abstract】 A mathematical model of the transport and conversion of "triple-nitrogen" of water in a mixed reservoir (lake) is developed in this article and the analytical solution to the influent and effluent quantity of the reservoir, namely, the analytical expression of the "triple-nitrogen" transport and conversion rules is also given. According to the analytical expression, we can compute the metabolic situation of the "triple-nitrogen" at any given time, and give the computed formula of the constant of "triple-nitrogen" conversion velocity. The concentration of "triple-nitrogen" metabolic rule of water in a reservoir can also be forecast, providing a scientific basis for avoiding the eutrophication and pollution from domestic sewage in the reservoir.更多还原
