Relating Analysis of Multi-Parameters of Constructed Wetland
Abstract:
In this paper, relations between multi-parameters of the tested wastewater before and after treatment by a constructed wetland were analyzed using Spearman Rank Correlation to get better understand of the processes taken in the system. The results show that COD level of the influent is positive related to DO concentration in the influent while slightly related to COD of the effluent. Concentrations of TN and ammonia in the influent are negative correlated to DO of effluent. DO and carbon source are the most important factors influencing the efficiency of the tested constructed wetland.
