【摘要】：水系连通是解决区域水环境问题的一个重要措施,而调水量确定是水系连通工程的关键问题之一。提出多功能区河道自净需水量计算公式,并将其运用于海口市中心城区水系连通工程河道水功能区水质所要求的最小需水量计算中,应用MIKE11水动力水质模型进行模拟。结果表明,计算流量是满足河道水功能区要求水环境质量标准的最小自净需水量,可作为海口市中心城区水系连通工程的调水流量。秀英沟、龙昆沟及美舍河的自净需水量分别为2.9 m~3/s、2.3 m~3/s和3.0 m~3/s;TP为计算河道自净需水量的控制性要素;满足该水量条件下,秀英沟、龙昆沟和美舍河水质可达Ⅳ类、Ⅴ类、Ⅴ类要求。
[Abstract]:Water system connectivity is an important measure to solve the problem of regional water environment, and the determination of water transfer is one of the key problems in water system connectivity engineering. This paper presents a formula for calculating self-purification water demand of multi-function river channels, and applies it to the calculation of minimum water demand required by the watercourse water function area of the connected river system in the central urban area of Haikou City. The MIKE11 hydrodynamic water quality model is used to simulate the formula. The results show that the calculated discharge is the minimum self-purification water demand to meet the water environmental quality standard in the river channel water function area and can be used as the water diversion flow of the water system connectivity project in the central urban area of Haikou City. The self-purification water demand of Xiuying ditch, Longkungou and Meishe rivers were 2.9 mNW / 3 / s-1 / s and 3.0 mN3s / s respectively as the controlling factors to calculate the self-purification water demand of the river, and the water quality of Xiuying ditch, Longkungou and Meishe rivers could reach class 鈪，
