A Study on Kinetic Experiment of Decarburization and Denitrification Reaction of Shallow Surface Flow Constructed Wetland

摘要：

　　In the shallow surface flow constructed wetland constructed in the laboratory,with domestic sewage as the study object,the most applicable conditions for removal of COD from the system are discussed to seek the rule of impact on denitrification capacity caused by hydraulic load.The optimal conditions for the removal of COD is obtained as 0.15m3/m2 · d hydraulic loading,the water height of 20 cm,COD influent concentration of 270mg / L.As the hydraulic load increases,the capacity of contaminant removal of the system firstly increases and then decreases.Based on such test data,a Level I reaction kinetic model is established.
