人工湿地是一种以生物膜原理为主的污水处理技术，基质选择是其关键技术之一。近年来，许多替代衬底已被研究和应用于化学武器，并进行了综述，有助于提供最新的信息化学武器的研发。本文在总结近10年来国内外对人工湿地出水基质（土壤、砂和砾石三种常规基质除外）研究进展的基础上，对人工湿地出水基质的研究现状进行了综述。根据基质在污染物去除中的主要作用，将其分类为离子交换基质、P吸附基质和电子供体基质。其中，由于其竞争性的污染物去除效率和最小化的废物处置，建议重复使用各种废物作为基质。关于基板的发展，未来的研究，以避免基板堵塞，以延长其在CW的寿命是必要的。
Substrate selection is one of the key technical issues for constructed wetlands (CWs), which works for wastewater treatment based mainly on the biofilm principle. In recent years, many alternative substrates have been studied and applied in CWs, and a review is conducive to providing updated information on CW R&D. Based on the intensive research work especially over the last 10 years on the development of emerged substrates (except for the three conventional substrates of soil, sand, and gravel) in CWs, this review was made. The substrates are categorized depending on their main roles in pollutant removal as ion-exchange substrates, P-sorption substrates, and electron donor substrates. Among these, reuse of various waste products as substrates was suggested due to their competitive pollutant removal efficiency and minimized waste disposal. Regarding substrate development, future research on avoiding substrate clogging to extend their lifetime in CWs is needed.
