Study on the Treatment of Wastewater from Cold Water Fish Breeding by an Integrated Wetland System
摘要
Abstract
In the study, an integrated wetland system ( IWS ) including constructed wetlands ( CWs) and modified natural wetlands( NWs) was established for aquaculture wastewater treatment located at the Bohai Town,Huairou District, Beijing. The results show that the removal efficiency of TN,TP, COD in the IWS is 61% ,57% and 66% , respectively. The overall removal efficiency of the IWS is greater than use a separately wetland treatment system. The correlation analysis show that significant relationship existed between the removal efficiency and influent concentration of TP and COD in NWs, and it also exist between the removal efficiency and influent concentration of TN and COD in CWs. As for the IWS,the removal efficiency of COD is positively correlated with that of TN and TP with the correlation coefficient of 0. 663 , 0. 689 respectively, under the significance level of 0. 05. However, the correlation between the removal efficiencies for TN and TP is not significant. IWS is integrating functions of NWs and CWs which could explore a new way to treat the wastewater discharged from cold water fish farming.关键词
