【摘要】 人工湿地是一种污水生物处理技术,因其具有独特的优势,而得到广泛的应用.其中,湿地植物在这个过程中扮演了重要的角色.湿地植物通过吸收、利用和吸附污染物,传输氧气,影响微生物和酶的分布,积累有机物等途径而起作用,从而降低污水中的氮、磷以及重金属等物质的含量,达到污水净化的目的.本文就湿地植物的作用及其机理进行了全面的论述.更多还原

【Abstract】 Constructed wetland is the biological technology of wastewater treatment,because it has particular predominance,it has been applied widely.In this process,wetland plants play an important role.By assimilating,utilizing and adsorbing pollutants,transmitting oxygen,influencing the distribution of microorganisms and enzymes,accumulating organic substances,wetland plants reduce nitrogen,phosphorus and heavy metals in wastewater and so on,which achieve the goal of purification of wastewater.The functions and mechanisms of wetland plants are discussed in this paper.更多还原
