摘要
研究了不同碳氮比对碳氮硫同步脱除的影响。结果表明,C/N在0.75/1→1/1→1.26/1变化时,反应系统中碳氮硫脱除效果较好,硫化物、硝酸盐及乙酸盐去除率分别保持在92%～100%,90%～100%和100%。综合考虑碳氮硫同步脱除过程,最佳碳氮比为1/1。同时探讨了碳氮比影响碳氮硫同步脱除的机理。
The purpose of this paper is to study the effect of different C/N ratio on the simultaneous removal of carbon,nitrogen and sulfur.The results showed that the system was hightly efficient in removing carbon,nitrogen and sulfur simultaneously.The removal rate of sulfur,nitrate and acetate was 92%~100%,90%~100% and 100% respectively.But the optimal C/N ratio was considered 1/1.The paper also discussed the mechanism of the simultaneous removal of carbon,nitrogen and sulfur.
