Abstract

Based on the visual environment of Stella software, we developed a kinetic model of nitrogen cycle in the surface-flow constructed wetland, and complied it in R language. We integrated various algorithms and functions such as programming calculation, data analysis and spatial analysis with the dynamic model, and greatly improved the analysis and prediction performance, the practicability and application ability of the model. We applied our model to study the maximum reduction capacity of ammonia nitrogen pollution load in Dashahe constructed wetland. Our model successfully established the function relationship between the water quality and the water flow. Furthermore, the optimal water inlet water, water quality and the maximum effect of reducing the ammonia pollution load was also determined.

Key words： Stella R language constructed wetland model pollution load reduction
