摘要

  • 摘要: 为研究中水消毒过程,对次氯酸钠消毒中水的折点加氯反应与消毒效果之间的关系进行研究。通过探讨加氯量位于折点曲线不同位置的消毒效果,分析接触时间和氨氮浓度的影响,得出了根据氨氮浓度确定的接触时间和加氯量公式。结果表明,氨氮浓度2 mg/L时,将加氯量控制在峰点附近接触反应60 min均可实现中水消毒要求。
    Abstract: The relationship of break point chlorination reaction and disinfection effects was studied to reveal process of reclaimed water disinfection using sodium hypochlorite as disinfectant. Contact time and chlorine dosage formulas according to ammonia nitrogen concentration were obtained through analyzing the relationship of positions of chlorine dosage on break point curve and corresponding disinfection effects, contact time and ammonia nitrogen concentration. The results showed that ensuring chlorine dosage enough to exceed that of break point with 30 minutes of contact time when ammonia nitrogen concentration was less than 2 mg/L, or chlorine dosage nearby that of peak point with 60 minutes of contact time when ammonia nitrogen concentration was more than 2 mg/L, both could achieve disinfection effects.
