Modelling and Simulation Eutrophication of Water Rivers

Abstract

In this paper presents the mathematical modelling of the flowing river eutrophication process based on model kinetic equations QUAL2E and developed using Scilab-Xcos program. This can be seen graphically by the evolution over time of: algal mass, organic nitrogen, ammonia, nitrite nitrogen, nitrate nitrogen, organic phosphorus, soluble phosphorus, dissolved oxygen concentration and Biochemical oxygen demand for the oxidation of organic substances containing carbon in water of a river, in the case of discharge of a certain wastewater flow untreated, having a certain organic loading.

Eutrophication of Water Body Based on Ecological Simulation Technology

“…The commonly used methods include pre reservoir interception, artificial wetland and natural wetland [5][6]. The second is to treat the polluted water body, including the absorption of nutrients, the utilization of various ions, the precipitation of heavy metal ions and the reduction of algae in the water body [7]. In recent decades, the rapid economic development and rapid population expansion have affected the natural landscape, weakened the self-regulation ability of the water ecosystem, and disrupted people's normal production and life [8].…”
