Different Configurations Constructed Wetland Sewage Treatment Comparison

Under the same conditions, a comparative research of the dynamics of three different artificial wetland sewage treatment effects was carried out, and comparative analysis of the results of its sewage purification. The results showed that when the artificial wetland ran 7 d, the optimization group, the control group and the traditional group of three artificial wetlands on average removal rates of total nitrogen were 68.79%, 13.06%, 46.82%, respectively; the average removal rates of total phosphorus were 88.99%,74.98%,28.68%, respectively; the average removal rates of COD were 76.03%, 33.34%,38.22%, respectively. It was indicated that the optimal group was most effective on the removal of TN,TP and COD. It was proved that without antagonism,the optimized configuration the wetland system was superior to the traditional type. By optimizing the system each wetland unit consisting of synergies strength,it could further enhance the treatment capacity,which also revealed new research directions and broad application prospects of artificial wetland system.
