尾水人工湿地中水生植物的应用研究进展

人工湿地因环境效益显著、经济效益好、应用范围广等特点,近年来在污水处理中得到广泛应用。植物作为生态系统的生产者,是湿地系统最为核心的要素。基于国内外人工湿地植物的研究和应用情况,阐述了植物在尾水人工湿地中的应用情况、影响植物净化能力的因素,以及湿地植物应用中存在的问题等,并对尾水人工湿地植物的研究和应用做出了展望。在参考大量文献基础上对湿地植物选择的原则方法、影响因素及主要问题进行了系统性的总结,为实际工程应用提供依据和参考。

Study on Application of Aquatic Plant in Tail Water Constructed Wetland

Sponge city is a new design idea, is aimed to control and store up the partial surface runoff, and then to utilize it. Thereby, it can let a city as a sponge fully absorb or supply the water resource for the urban environment when in need. The implementation of sponge city idea can not only satisfy the demand of ecological environment benefit of urban development, but also bring the good landscape effect to the urban construction. Taking a semi-underground wastewater treatment plant WWTP in Hainan Province as an example, the design idea of sponge city is used to in the ecological design of rainwater and sewage systems in WWTP, which can reduce the influence of urban WWTP construction on the surrounding ecological environment. The sponge rainwater drainage system mainly includes the permeable pavement, gravel drain, conveying-type grassing ditch and sunken greenbelt.
