Method of measuring concentration of dissolved organic nitrogen in sewage |
| abstract |
A method of measuring concentration of dissolved organic nitrogen in sewage. The method includes: filtering a sewage sample using a filter membrane; measuring the concentrations of total dissolved nitrogen (TDN), ammonia nitrogen (NH4+), and nitric nitrogen (NO3−) in the sewage sample, respectively designated as CTDN(I), CNH4+(I) and CNO3−(I); calculating the ratios of (CNH4+(I)+CNO3−(I))/CTDN(I) and CNO3−(I)/CNH4+(I), and according to the ratios, calculating the concentration of dissolved organic nitrogen (DON) in the sewage sample. |
