摘要
人工湿地是污水处理和城市景观营造的有效手段。文中以一个景观水域配套人工湿地污水处理系统为例,阐述了湿地设计及景观布设的基本情况,采用水质监测、植物长势评估、藻类生长情况观测等方式,分别对湿地建成运行后初始50天运行效果和3年间运行效果进行了分析和评估。结果表明,初次运用人工湿地系统时,除总磷外,景观水域各项水质指标均由V类变为Ⅳ类水质,效果理想;人工湿地系统应用于景观水域水质净化时也形成了可循环的生态系统,即使景观水域水位降低,需要补给附近市政河道水体时,人工湿地也会迅速净化水质降低总磷量,避免水源再次污染。该人工湿地技术在景观水体净化中具有良好的实际效果和应用推广价值。
Artificial wetland is an effective means of sewage treatment and urban landscape construction. Taking the constructed wetland sewage treatment system as an example,the paper expounds the basic conditions of wetland design and landscape arrangement,and adopts the methods of water quality monitoring,plant growth assessment and algae growth observation. This paper analyzes and evaluates the running effect of wetland in the first 50 days and 3 years respectively. The results showed that the water quality index of landscape water was changed from V to IV in addition to total phosphorus. When the artificial wetland system is applied to the water quality purification of landscape waters,it also forms a recycling ecosystem. Even if the water level of landscape waters is reduced and it is necessary to supply nearby municipal river bodies,the constructed wetlands will quickly purify the water quality and reduce the total phosphorus content,avoiding water source pollution. The artificial wetland technology has good practical effect and application value in landscape water purification.
