基于MIKE 11 Ecolab模型的梁滩河流域水污染问题探讨

基于MIKE 11 Ecolab模型构建了梁滩河流域水文、水动力和水质综合数学模型，分析了该流域河道的水质时空变化特征，研究了不同预案对该流域水质变化趋势及水质改善的效果。结果表明，生活污水的处理应是未来梁滩河流域治理的重点，应降低该流域水体的氨氮浓度，关注水体中总氮、总磷的含量，生活污水处理应采用集中和分散处理相结合的原则。

Research on Water Pollution Problem of Liangtanhe Basin Based on MIKE 11 Ecolab Model

Based on MIKE 11 Ecolab model, we build hydrological, hydrodynamic and water quality integrated model in Liangtanhe basin. And then it analyzes temporal and spatial characteristics of river channel water quality. Moreover, the effect of water quality changes and improvement is studied according to different counterplans. The results show that dealing with domestic wastewater is the key point of pollution control in Liangtanhe basin in the future; it is necessary to reduce ammonia nitrogen concentration of rivers and control total nitrogen and total phosphorus of water body; it is better to combine centralized treatment and decentralized treatment to deal with domestic wastwater.
