| Abstract: | The nitrate nitrogen in the effluent after sewage treatment will enter the anaerobic zone through return sludge system,reducing the effectiveness of phosphorus removal.The best way to ensure the phosphorus removal efficiency is to control the content of nitrate nitrogen in the effluent.Ultraviolet spectrophotometry is a convenient and fast way for determining the content of nitrate nitrogen.By using it,the deviation between the measured value and the actual content of standard sample would be below 3.1%. |
