为检验流域/区域水量水质联合配置理论方法的可行性,在湟水干流进行实例应用研究。进行了基准年的供需平衡、耗水平衡分析和水质模拟,对当地水质型缺水进行了识别。构建需水方案和工程方案集,以需水中方案和工程方案3为推荐方案。以改进的“三次平衡”思想为指导,模拟现有污染治理水平下,2030年水功能区纳污量;分析了耗水平衡和水功能区纳污能力的变化趋势,进行了污染物总量控制分配。结果表明,随着本研究方案的实施,各水资源分区生态用水比例均在60%以上;水质型缺水率仅为0.4%;2030年 COD和氨氮纳污量分别为4585.51 t和244.63 t,污染物总量得到控制;各水功能区水质均达标。证实流域/区域水量水质联合配置理论方法可行。
In order to test the feasibility of basin/regional water quantity and quality of joint configuration theory, taking the main stream of Huangshui River for example, this study analyzes the supply-demand bal- ance and water consumption balance, simulates the change of water quality and identifies the water short- age type, constructs the water demand scheme and engineering scheme, and puts forward the recommended scheme. Taking the improved three-time balance as the guidance, the quantity of pollutants received in wa- ter function area in 2030 were simulated under the current pollution control level, the trend of water envi- ronment capacity was analyzed and the controlling pollution amount was allocated. The results show that with the scheme implementation, the proportion of water ecology for each water resources district will be above 60 % with only 0.4 % of water shortage induced by water pollution; the quantity of COD and ammo- nia nitrogen will be 4,585.51t and 244.63 t into the main water functional areas in 2030 respectively, and the pollution amount will be controlled, meeting the water quality requirements for each water functional ar- ea. Basin/regional water quantity and quality joint configuration method is feasible.
