ABSTRACT
For this paper we simulated wastewater containing organic phosphorus degradation process across the
wetland via organic phosphorus containing solutions of different pH values slowly passing the simulation
groove so as to explore the chemical kinetic characteristics of phosphorus migration in the aqueous
backgrounds of different wetlands. Our study shows that the migration performance of organic phosphorus
in the wetland declines while pH value increases, and that the mineralization of organic phosphorus in clay
pan increases with enhanced pH value. The mineralization rate of organic phosphorus in the eighth day
may reach over 74% (pH≥7) or above 90% when pH = 9.0. The concentration of PO43-, which is the direct
product of mineralization of organic phosphorus, decreases somewhat when the pH value increases or as
time passes. Our study provides the parameter basis to explore the purification mechanism and determine the
chemical kinetic mode of organic phosphorus migration in aqueous background of the wetland.
