中文摘要:
      [目的]了解引黄济青干渠水质安全风险,为干渠安全管理提供依据,保障青岛居民饮水安全。[方法]基于干渠沿线监测数据,识别出决定黄济青干渠水质的关键控制因子,并通过进一步的分析筛查风险因子,确定水质安全风险清单。[结果]干渠水质先好转后恶化,营养物质是影响干渠水质的主要指标,但南水北调水明显缓解了干渠的富营养化。宋庄分水闸至棘洪滩水库进水处之间的供水干渠存在较大的铁和磷污染源。[结论]关键控制因子识别法应用于长距离调水工程是可行的;干渠现有安全风险包括黄河水中氮磷营养物质及南水北调水中有机物和硫酸盐,以及干渠后半段铁、磷和有机物污染;潜在安全风险为南水北调水汇入量的变化或湿地系统失效可能造成富营养化和金属离子释出。
英文摘要:
      [Objective] To understand the risk of water quality safety in main canal for water diversion from Yellow River to Qingdao City, in order to provide basis for the safety management of main canal, and to ensure the the drinking water safety of Qingdao City.[Methods] Based on the monitoring data obtained along the main canal, the key control factors which determine the water quality in the main canal were identified, and a list of the water quality safety risks was determined by further analysis of the risk factors.[Results] The water quality of the main canal was improved firstly, and then deteriorated. Nutrients were the main indexes affecting the water quality of the main canal. The south-to-north water diversion project alleviated the eutrophication of the main canal obviously. There were larger sources of iron and phosphorus pollution in the main trunk canal between Songzhuang water diversion and water inlet of Jihongtian reservoir.[Conclusion] It is feasible to apply the key control factors identification method in the long distance water diversion projects. The existing safety risks in the main canal include total nitrogen and total phosphorus from the Yellow River, organic matter and sulphate from the south-to-north water diversion project, and iron, phosphorus and organic pollutants in the latter half of the main canal. The potential safety risks are eutrophication and release of metal ions caused by the changes of water intake volume in south-to-north diversion or the Yellow River and the failure of the wetland system.
