摘要
通过对汾河太原城区段河流现场调查和水质现状监测,分析了该河段的主要水质特征,确定了汾河太原城区段的主要污染物和污染控制因子为BOD和NH3-N。应用系统的方法,将河段进行概化,在BOD和DO耦合模型的基础上,加入NH3-N对水体溶解氧影响的作用,建立了该河段的水质模型,结合历年的水文资料并应用实测资料进行模型的参数率定,经模型验证,模拟结果与该段河流的实际水质监测结果基本吻合,表明该模型具有一定的合理性和实用性。
Based on the field investigation and long period regularly monitoring on the main section in Taiyuan reach of Fen River, the water quality characteristic was analyzed and it was ascertained that the main pollutes and controlled factor are BOD and. NH3-N. The system engineering method was used to abstract the Talyuan reach of Fen River and build the water quality model with the BOD and NH3-N effects on DO. With historical hydrology data and monitoring data, the models were validated and proved to be suitable to simulate water quality on Taiyuan reach of Fenhe River.
