Eco-river channel building is an effective remediation technology for water body. Selecting appropriate matrix material to build eco-river channel can improve its purification capacity on the pollutants. In this paper, we conducted a comparative study on the adsorption capacity of gravel, sand and zeolite on nitrogen and phosphorus and made an initial analysis on its adsorption mechanism. The results show that, Freundlich isotherm equation can better describe the adsorption properties of those three materials, shown as follows: zeolite>gravel> sand. Thus, we should select gravel or zeolite with greater adsorption ability as matrix material to build eco-river channel, for it will not cause secondary pollution for water environment.
Key words: Eco-river channel, natural materials, repair, secondary pollution, , ,
