摘要
论述了基于MIKE11/21和Ecolab模型建立的邕江、南湖和竹排江水系的水质水量耦合模型,分析南湖环水系水质变化特征,研究不同的外江引水方式和截污减污程度下,该区域总氮、总磷和氨氮水质变化趋势及水质改善的效果。结果表明,凤岭截污和竹排江生活污水的处理应是未来南湖环水系治理的重点。
Nanhu Lake ring water system consists of Yongjiang River, Nanhu Lake and Zhupaijiang River. A water quality-quantity coupling model was established based on MIKE 11/21 and Ecolab to analyze the water quality vari- ation characteristics of Nanhu Lake ring water system. In view of various water diversion modes from external river and different pollutants interception or reduction degrees, water quality improvement effects and change trend of water quality indexes such as total nitrogen, total phosphorus and ammonia nitrogen, were studied. The results of study demonstrate that interception of pollutants at Fengling and treatment of domestic sewage in Zhupaijiang River will be key points for Nanhu Lake ring water system.
