摘要
人工湿地是一种污水生态处理技术,具有投资省、运行管理方便、出水水质稳定的优势,且具有一定景观效果,因此被广泛应用于污水处理领域。然而,该技术在实际工程应用中仍存在一定的问题,比如设计不规范、易发生堵塞,致使湿地使用寿命及处理性能受限。人工湿地型式选择、基质类型和粒径、植物种类和配置以及进水方式和运行参数是影响人工湿地运行寿命及净化效果的主要因素。从以上四个方面对目前研究成果进行总结,阐述了各因素对人工湿地设计的影响及其机理,并对人工湿地的设计研究进行了展望,以期为人工湿地在实际工程设计中提供借鉴。
Constructed wetlands as a wastewater eco-treatment technology were widely used in sewage treatment because of less investment, less-operational-requirements, stabilization of water quality. However, many problems are found in the practical application of Constructed Wetland, such as substrates are easily plugged and non-standard design, result in shorten the life of the Constructed wetlands and decrease the performance.The main design parameters and operational conditions of Constructed wetlands including type of Constructed Wetlands, type and size of substrates, type and combination of plants, feeding mode and operating parameters affect the life and performance of Constructed wetlands, research achievement about above four aspects were summarized, and the influence of design parameters and operational conditions on the design of Constructed Wetlands and their mechanism were explained. In the end, the design and reasearch of Constructed Wetlands was summarized and prospected, in order to providing instruction for the Constructed wetlands design using in engineering.
