Review on plants selection and application effects in ecological floating beds based on water purification

Abstract

Due to the variety of plants and different types of polluted water quality, there is no unified standard for the application types of floating bed plants. Therefore, this paper summarizes and analyses 815 articles related to "ecological floating bed" and "plant water purification" that have been screened and identified in the search results of CNKI. According to plant types and water quality types, the purification effects of floating bed plants on different pollutants are comprehensively described to comprehensively evaluate the actual effects of plants in floating bed applications, which provides a useful scientific reference for the reader to screen and apply the plant in the floating bed.
