Abstract

This paper presents the mathematical model of the nitrification process starting from the kinetic equations describing this process. The mathematical model was developed using Scilab-Xcos program and allows the visualization in time of the water concentration evolution of the following parameters: organic nitrogen (N_org), ammonia nitrogen (NH_3-N), nitrite nitrogen (NO_2-N), nitrate nitrogen (NO_3-N), oxygen (C) and biochemical oxygen consumption for the oxidation of organic substances containing carbon (L_C). Also in this work is presented an example of simulation of the above mentioned parameters.
