Abstract:

针对感潮河网区水系、水动力以及水利工程特点，以网河区一维水动力数学模型、一维水质数学模型以及闸泵控制模拟模块为基础，建立了基于闸泵群调度的感潮河网区水量水质调控模型，开展了珠江三角洲典型研究区的水量水质调控方案研究。结果表明，调度时段为小潮至中潮、采用单一水闸排水时水量水质调控效果最优；调度后内河涌蓄水量增加242.9万m³，COD平均浓度由40 mg/l降至29.7 mg/l，采用科学的闸泵群调度，有效改善了感潮河网区内河涌水环境、显著增加了淡水资源量；该模型与珠江三角洲一维潮流模型、水质模型、盐度模型以及人类活动影响下的典型区陆面水量水质模型的耦合有待进一步完善。
In view of the characteristics of the river network, hydraulic and structures, a water quantity and quality operation model based on sluice-pump group control in tidal river network is developed which is coupled with 1D hydrodynamic & water quality model, and sluice-pump control module. The established model is used for regulating the quantity and quality in the typical area of Pearl River Delta. The results suggest that the best operation period is from neap tide to moderate tide with one drainage pump, and a scientific operation will significantly improve water environment and increase water storage in tidal river network which increases the water storage by 2.429 million m³ and reduces the COD concentration from 40mg/l to 29.7mg/l. The coupling of this model, 1D hydrodynamic & water quality & salinity model in the Pearl River Delta, and land water quantity quality model considering the effect of human activity needs further study.
