摘要： To explain the detailed process involved in phosphorus removal by periphyton, the periphyton dominated by pho-toautotrophic microorganisms was employed in this study to remove inorganic phosphorus (P_i) from wastewater, and the removal kinetics and isotherms were then evaluated for the P_i removal process. Results showed that the periphyton was capable of effectively removing P_i that could completely remove the P_i in 24 h at an initial P_i concentration of 13 mg P L~(-1). Furthermore, the P_i removal process by the periphyton was dominated by adsorption at initial stage (~24 h), which involved physical mechanistic process. However, this P_i adsorption process was significantly influenced by environmental conditions. This work provides an insight into the understanding of phosphorus adsorption by periphyton or similar microbial aggregates.
