Abstract

In order to investigate the feasibility of treatment of dairy farm wastewater by constructed wetland and to provide the operation parameters for a full scale constructed wetlands to improve the quality of effluent water, A pilot test was conducted with a plug flow constructed wetland to treat dairy farm wastewater in Ji´nan city. The results show that, under influent loading rate 3m³·d^-1, the average removal efficiency of chemical oxygen demand (COD), Total phosphorus (TP), total nitrogen (TN), and ammoniacal nitrogen(NH₄⁺-N) in the plug flow constructed wetland were 66.98%, 57.49%, 57.16%, and 55.09%, respectively. Temperature has a positive effect on the removal rate. The study indicates that t purifying dairy farm wastewater by constructed wetland is the combined actions of physical chemistry, plants and microorganism.
