摘要
水质模型的应用,是水质评价及预测的重要手段。依据调查与监测数据,建立了苏子河的QUAL2K水质模型,对该河BOD、COD、NH3-N三种水质参数进行验证,结果表明:苏子河5个监测点的水质指标模拟的相比误差均在10%以内,计算值与实测值相关性较好,能够达到模型精度的要求;对苏子河水质参数模拟精度最高的是NH3-N,其次是BOD和COD;对苏子河中游模拟误差最大,而大伙房水库入库口模拟误差最小。
Application of water quality model is of an important means of water quality evaluation and prediction. Based on the data of investigation and monitoring, this paper established the QUAL 2k water quality model of HunHe river tributaries- Suzi River, completed parameters estimation between simulation and monitoring values, and verified through the water quality parameter such as BOD, COD and NH3 - N. The results show that the error amount of calculated and measured values is less than 10% about the 5 monitoring points of Suzi River. The pertinence between calculated and measured values is better, and able to meet the requirements of model accuracy. The highest precision is NH3 - N about Snzi River water quali- ty parameters simulation, and then are BOD and COD. The simulation error is maximum in Suzi River middle reaches, and minimum in downstream into estuaries.
