| 摘 要： | 水质预报预警对于防范水污染、降低水污染风险及其带来的损失、保障用水安全及水环境质量等具有重大意义。提出了一种基于QUAL2K模型的水质模拟预警方法,包括水质模拟预测、预警指数计算和警情确定,以海河流域鹤壁市卫河为例进行实证研究。研究结果表明:基于QUAL2K模型模拟精度分别为COD 97.7%、NH_3-N 98.5%,水质模拟效果较好;所选河段预警时段内COD基本处于无警和轻警2个级别,氨氮大多是巨警,浓度严重超标,是导致监测断面预警指数高的主要原因。

| Abstract: | Water quality forecasting and early warning is of great significance to prevent water pollution, reduce the risk of water pollution and its loss, and ensure water safety and water quality. The water quality forecasting and early warning method based on QUAL2K model was put forward, simulating and forecasting of the water quality, including simulation and prediction of water quality, calculation of early warning index, and determination of warning situation. Taking the Hebi Wei River in Haihe Basin as an example, the results showed that:the simulation accuracy of COD and NH3-N based on QUAL2K model was 97.7% and 98.5%, and the effect of water quality simulation was better; during the warning period of the selected river, the COD sounded normal or a little alert, while the concentration of ammonia nitrogen was seriously exceeded, which was the main reaseon for the high alert index in the study area. |
