干旱地区市区性河流水质研究

Water Quality Study for Urban River in Drought Area

通过对市区性河流玉门河现场调查和水质现状监测,分析了该河流的水质特点,得知本河流污染物耗氧机制主要为碳化耗氧。应用定量分析方法,将河段进行概化,建立了BOD-DO耦合模型,并结合历年的水文资料和实测资料确定模型的参数,经模型验证和模拟结果与该段河流的实际水质监测数据对比其结果基本吻合,表明该模型具有一定的合理性和实用性。

On the basis of Based on the field investigation and long period regularly monitoring on the Yu Men River,the water quality characteristic was analyzed,indicating that the carbonaceous material in river predominated the oxygen consumption in pollutant degradation process.The system engineering method was used to Abstract the urban river and to build the water quality couple model on BOD and DO.With historical hydrological data and monitoring data,the models were validated and proved to be suitable to simulate water quality on Yumen river.
