Chemical kinetic characteristics of phosphorus migration in aqueous background of wetland


Warianty tytułu

Języki publikacji



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.
