华容河水质模拟分析与调度方案研究

Water Quality Simulation Analysis and Scheduling Scheme of Huarong River

摘要: 根据文献数据及水环境监测数据，分析了华容河的污染源、水环境质量等水环境现状条件。采用一维水质数学模型，根据华容河调弦闸和六门闸的不同调度运行方式及华容河不同的运行水位，设定不同的数值模拟情景。分析了华容县城断面的水环境质量变化情况，以及调弦口闸引水对华容县城水环境质量的影响。由于华容河水环境质量较差，对于蓄水较低的26.06 m水位引水200 m3/s时，华容县城水质全断面达到长江水质需要300小时(12.5天)。由于长江水位在不断下降和调弦口进水条件不利，华容河水环境保护的可持续性还有待深入研究。

Abstract: According to the literature data and water environmental monitoring data, the present conditions of water environment such as pollution sources and water environment quality in the Huarong River are analyzed. According to the different operation modes of the Tiaoxian sluice and Liumen sluice and the different operation water levels of the Huarong River, different scenarios are simulated numerically using one-dimensional water quality model. The water environment quality at the Huarong county section is analyzed and the impact of Tiaoxiankou diversion gate on water environmental quality is evaluated. Because of the poor environmental quality, it takes 300 hours (or 12.5 days) for the Huarong county to reach the water quality of the Yangtze river when the water level is low. As the water level of the Yangtze River is declining and the intake condition of the tuning inlet is unfavorable, the sustainability of the environmental protection needs to be further studied.
