摘　　要：雨水管网是城市关键基础设施,出现突发性水体污染事件时,通过溯源分析方法查询源头具有重要意义。以陕西省西咸新区空港新城南排水分区为例,采取人工采样方法收集并分析24条主干道管段雨水井内水流与水质情况,探究污染原因与机制。结果证明:张裕酒庄门口处的检查井内设有流量调节阀且该阀门开度几乎为零,致使老民航路段4-11号污水管道长期满流运作,维持有压状态,最终使中隔墙开裂渗漏,使雨水井室内充满污水。该研究结论为后续空港新城及其他地区管网水污染溯源分析与处理工作提供了理论科学依据。Stormwater pipe network is a key urban infrastructure.It is of great significance to search the source of water pollution by traceability analysis method when sudden water pollution events occur.Taking the drainage area of Konggang New city South in Xixian New District of Shaanxi province as an example,the water flow and water quality in the stormwater Wells of 24 main road sections were collected and analyzed by manual sampling method to explore the pollution causes and mechanisms.The results show that there is a flow regulating valve in the inspection well at the entrance of Changyu Winery,and the opening of the valve is almost zero,which causes the sewage pipe No.4-11 of the old civil aviation section to operate at full flow for a long time and maintain a state of pressure,and finally cracks and leaks the middle partition wall and fills the rainwater well with sewage.The conclusion of this study provides a theoretical and scientific basis for the follow-up analysis and treatment of water pollution in Airport New city and other areas.
