焦化A/A/O废水处理系统运行中存在的问题及优化措施

Problems and optimization measures in the operation of coking A/A/O wastewater treatment system

A/A/O(厌氧/缺氧/好氧)工艺是废水处理常见的工艺流程之一。在传统的A/A/O工艺中,厌氧池对于焦化废水的可生化性效能有待进一步增强。通过对传统工艺流程的分析,找出废水可生化性处理过程中的问题和不足之处,并提出在厌氧池与缺氧池之间增加新的装置,促进消化污泥的循环效率,进而实现焦化A/A/O废水处理系统运行中的优化。

A/A/O(anaerobic/anoxic/aerobic)process is one of the common processes of wastewater treatment.In the traditional A/A/O process,the biodegradability and efficiency of anaerobic tank for coking wastewater need to be further enhanced.Through the analysis of traditional process flow,the problems and deficiencies in the biochemical treatment of wastewater are found out,and it is proposed to add a new device between anaerobic tank and anoxic tank to promote the circulation efficiency of digested sludge,so as to realize the optimization in the operation of coking A/A/O wastewater treatment system.
