[Objective] The research aimed to study the influences of different factors on the removal effect of phosphorus in the substrate of constructed wetlands. [Method] Through the static-shaker experiment and dynamic-adsorption column experiment, the influences of types of substrate, temperature, particle diameter of substrate on phosphorus removal of the substrate were investigated. [Result] The phosphorus removal efficiency of various substrates differed dramatically, with the maximum adsorption amount of steel dregs > shale > zeolite > gravel. Phosphorus absorption parameters obtained by different experimental methods were different. The adsorption capacity of phosphorus by substrate was enhanced gradually with the increasing of temperature. There was a negative relationship between particle diameter of substrate and phosphorus adsorption. [Conclusion] The research provided theoretical guide for the selection of substrate in constructed wetlands and wetland operation.
