人工湿地基质研究进展

Research progress of substrates in constructed wetland

摘要:

人工湿地是处理不同领域复杂污染物的有效方法, 已经被广泛应用 。植物—基质—微生物三者之间协同作用是 人工湿地去除污染物的主要机理,其中基质是系统中重要的组成部分,但 日趋复杂的污染物组成对提高人工湿地性能和可 持续性的基质提出了新的要求 。本研究综述了人工湿地常用基质的理化性质、污染物去除效率,归纳了基质在人工湿地处 理过程中遇到的问题,进一步结合国内外学者提出的解决方案,总结并提出了人工湿地优化措施,为人工湿地构建及处理 效率优化提供了依据。

Abstract:

Artificial wetlands is an effective solution for addressing complex environmental pollutants . The synergy among plants, substrates, and microorganisms is the key mechanism driving the removal of pollutants in artificial wetlands, with the sub- strate playing a particularly vital role . However,the growing complexity of pollutants necessitates the development of sustainable substrates and more efficient artificial wetland systems . This study begins by conducting a comprehensive review of the physico- chemical properties, pollutant removal mechanisms, and efficiency of commonly used substrates . challenges faced by substrates during the treatment process in constructed wetlands are also brought to the forefront. By amalgamating the solutions proposed by both domestic and foreign scholars,this research outlines and proposes optimization measures for constructed wetlands . In conclu- sion,this study serves as a foundational resource for the construction of constructed wetlands and the enhancement of treatment efficiency in the face of evolving environmental challenges .
