| Abstract: | Ammonia-nitrogen in influent and effluent of biological falling water aerated filter were determined by enzymatic determination and N-reagent spectrophotometry method.The comparisons between the two results were made by means of t test in mathematical statistics,which indicated that the enzymatic determination had advantages due to its accuracy,simplicity,rapidity,wide range of measurement and less interference,which was suitable for determining the ammonia-nitrogen in wastewater. |
