title = "Study on treatment of ammonium nitrogen in desulfurization and denitrification wastewater with sodium hypochlorite",
abstract = "Based on the investigation of measurement method of ammonium nitrogen (NH4-N) desulfurization and denitrification wastewater (DDW) by distillation method, effects of pH, Cl/N and the initial concentration of NH4-N on the removal of NH4-N in DDW by sodium hypochlorite were studied. Results of parallel test and standard recovery test demonstrated good reliability and accuracy of the distillation method for the measurement of NH4-N in DDW. The NH4-N removal efficiency increased with pH from 5.0 and 8.0, and then decreased with pH higher than 8.0. Therefore, the optimum pH value was 8.0 with NH4-N removal efficiency of 74.7\%. NH4-N removal efficiency was increased from 16.9\% to 84.1\% with Cl/N molar ratio rose from 1 to 5. The initial concentration of NH4-N showed insignificant effect on the removal amount of NH4-N, and the removed NH4-N was about 12\textasciitilde{}13mg/L with the addition of 4.86mmol/L sodium hypochlorite.",
