人工湿地基质研究进展

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。本文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。

Research Development of Substrates in Constructed Wetland

Artificial wetlands represent 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 substrate 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 physicochemical properties, pollutant removal mechanisms, and efficiency of commonly used substrates. Challenges faced by substrates during the treatment process in artificial 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 artificial wetlands. In conclusion, this study serves as a foundational resource for the construction of artificial wetlands and the enhancement of treatment efficiency in the face of evolving environmental challenges.
