【摘要】：人工湿地是处理受污染的公园景观水体的一种新型的、行之有效的方法,能够在去除水中的污染物的同时,兼具观赏性能和经济效益。北京园博湖人工湿地系统作为目前亚洲最大的潜流型人工湿地,是我国的湿地系统研究的重要研究对象,也是承载永定河丰台段再生水水源净化的重要工程项目。本研究以北京园博湖人工湿地系统作为研究对象,根据北京园博湖人工湿地系统在不同季节的情况,按照夏、冬两季选择合适的检测时间做好水质检测工作。在潜流湿地的四个分区中,每个区分别选取三个单元湿地进水阀井及与其相对应的出水阀井作为监测点,并取其平均值作为监测数据。对监测指标进行处理后进行数据分析、对比,结果表明,北京园博湖人工湿地系统对NH4-N、TP、COD、SS等指标能起到一定的净化效果,特别是对NH4-N的去除率最高可达到98.63%,平均总去除率达到73.17%。北京园博湖人工湿地系统的净化出水对指标的去除效率基本能够满足设计标准,但各区的净化效果存在差距、冬季和夏季的净化效果相差较大。因此需建立健全北京园博湖人工湿地系统的管理机制、加强对水生植物的管理和维护、加大对游人的宣讲力度以减小游人对北京园博湖人工湿地系统的影响。
[Abstract]:Constructed wetland is a new and effective method to treat the polluted park landscape water. It can remove the pollutants in the water at the same time as well as the ornamental performance and economic benefit.As the largest subsurface constructed wetland in Asia, Beijing Yuanbo Lake constructed wetland system is an important research object of wetland system in China, and also an important project to carry the reclaimed water source purification in Fengtai section of Yongding River.In this study, the Beijing Yuanbo Lake artificial wetland system is taken as the research object. According to the situation of Beijing Yuanbo Lake artificial wetland system in different seasons, according to the summer, winter and two seasons to select the appropriate detection time to do water quality detection.In each of the four subsurface wetland zones, three unit wetland intake valve wells and their corresponding outlet valve wells are selected as monitoring points, and their average values are taken as monitoring data.After processing the monitoring indexes, the data were analyzed and compared. The results showed that the constructed wetland system of Beijing Yuanbo Lake could purify NH _ 4-N ~ (2 +) TPCODSS and other indexes to a certain extent, especially the highest removal rate of NH4-N was 98.63 and the average total removal rate was 73.17%.The removal efficiency of the purified effluent from Beijing Yuanbo Lake constructed wetland system can basically meet the design standard, but there is a gap between the purification effect of each district and the difference between winter and summer.Therefore, it is necessary to establish and improve the management mechanism of Beijing Yuanbo Lake artificial wetland system, strengthen the management and maintenance of aquatic plants, and increase the propaganda to visitors in order to reduce the impact of visitors on the Beijing Yuanbo Lake constructed wetland system.
