A laboratory-scale completely autotrophic nitrogen removal over nitrite (Canon) biofilm reactor was applied to remove nitrogen and organic carbon from swine digester liquor for 150 d. A stable nitrogen removal rate was reached after a three-week adaptation period. The nitrogen loading rate of influent were 0.20±0.04, 0.26±0.04, 0.26±0.07 kg N m(-3) d(-1) in period I, II and III, respectively. Nitrogen removal rates reached 0.096, 0.133 and 0.104 kg N m(-3) d(-1) when the C/N ratios of liquor… CONTINUE READING
