人工湿地基质类型及其去污能力的影响因素

Influencing factors of Substrate Types of Constructed Wetland and their Decontamination Ability

人工湿地作为一种生态污水净化处理的系统技术,具有很高的生态环保价值,其中基质作为人工湿地中最重要的组成部分之一,对人工湿地净化污水的效果起重要作用。为人工湿地基质的应用提供参考,概述了基质的种类、去污特性,从基质粒径、填充类型、组合配置、污水性质、基质堵塞等方面分析了影响人工湿地基质去污能力的因素,同时提出了人工湿地基质今后的研究方向。

The constructed wetland is used as a sewage purification treatment technique with a higher ecological environmental value.The substrate is one of the most important components in constructed wetland,which plays an important role in sewage purification of constructed wetland.The types and decontamination characteristics of the substrates are reviewed and the factors influencing decontamination ability of the substrates in constructed wetland are analyzed from aspects of substrate size,filling type,combination configuration,sewage property and substrate clogging to provide a reference for substrate application in constructed wetland.The future research direction in substrates of constructed wetland is prospected at the same time.
