基于QUAL2K模型的农田排水沟水质模拟研究

Study on water quality simulation of farmland drainage ditches based on QUAL2K model

水质模型是研究农业非点源污染、进行水质评价及预测的重要手段。根据实地调查与监测数据,利用QUAL2K模型模拟了农田排水沟塘对于排水中氨氮、总磷2种污染物的去除情况。QUAL2K模型可用于农田排水沟水质变化过程的模拟预测,为优化排水沟塘系统的污染物去除能力提供理论依据。

Water quality model is an important method to study agricultural non-point source pollution,evaluate and predict water quality.According to the field investigation and monitoring data,QUAL2K model was used to simulate the removal of ammonium nitrogen and total phosphorus in the drainage of farmland drainage ditches and ponds.QUAL2K model could be used to simulate and predict the water quality change process of farmland drainage ditches and provide theoretical basis for optimizing the pollutant removal capacity of drainage ditch and pond system.
