摘要
对于有污泥厌氧消化系统的污水处理厂,传统方法将污泥消化液直接回流到污水厂处理工艺前端。由于污泥消化液氨氮浓度高,C/N比低,旁侧处理后再回流到污水厂主反应区,可以节省投资和运行费用,提高污水厂脱氮效果。因此单独处理污泥消化液是常规工艺的有效补充。本文分析归纳了污泥消化液旁侧处理的必要性,阐述了目前各种消化液处理技术的优缺点和实际应用情况,并提出污泥消化液旁侧生物处理技术的发展趋势。
Reject water of digested sludge causes significant internal nitrogen loading to a wastewater treatment plant. Due to high concentration of ammonia it is more effective to treat the reject-water not directly in the main purification process to apply a separate biological treatment procedure. In this study the benefit of separate treatment for reject water is discussed, the development of research and application of novel special biological separate treatment processes. And at last the suggestion for future study has been introduced.
