Summary:Recently constructed wetland have been widely used in wastewater treatment because of its low energy consumption and its simple operation. A research for removing nitrogen in the treated tannery wastewater by using constructed wetland have been conducted. Two unit of constructed wetland were used. Each unit was vegetated with Equisetum hyemale and Echinodorus palaefolius respectively. Both unit were then operated with subsurface flow system by varying the residence time at 3.125; 2.083; and 1.563 days. The results showed that the optimum effectiveness of nitrogen reduction were 83.67% with a residence time of 3.125 days and 70.29% with a residence time of 2.083 days for Equisetum hyemale and Echinodorus palaefolius respectively. Nitrogen reduction rate constant of 0.275 by using the formula of the USEPA was only suitable for wetland with Equisetum hyemale with R2 of 0.880.
