生物脱氮处理过程中氮素转化规律的研究

STUDY ON THE TRANSFORMING RULES OF NITROGEN IN THE BIOLOGICAL NITROGEN REMOVAL TREATMENT

以肉类加工废水为研究对象,采用ABR改-进型SBR组合工艺分析其脱氮处理过程中的氮素转化规律,确定ABR最佳水力停留时间为6—8h,氨氮增长速率在90%—196%及SBR最佳运行工况.

This paper studied the meatpacking wastewater treatment for nitrogen removel by combined ABR with sequencing batch reactor. The transform among various forms of nitrogen in the biological meatpaking wastewater treatment for nitrogen removal was investigated and discussed. The experimental result shows, to pull off nitrogen the most power period is between 6 and 8 hours, the best operation conditions of SBR is also confirmed. The study will give some theoretical instruction to biological nitrogen removal in the treatmeatment of meatpacking wastewater.
