高污泥浓度下A/A/O工艺及其改良工艺运行效果对比

Comparison of Operation Effect between A/A/O and Improved A/A/O Processes under High Sludge Density Condition

在阐述A/A/O工艺及其改良工艺的技术原理基础上,对A/A/O工艺及其改良工艺在实际生产中的应用及其脱氮除磷处理效果进行对比分析,实际生产应用结果表明,在高污泥浓度低污泥负荷的条件下,两种工艺均能保持较为理想的脱氮除磷效果。

The technical principle of A/A/O process and the improved A/A/O were explained. Removal efficiency of nitrogen and phosphorus were analyzed in the application of A/A/O process and improved A/A/O in actual production. The application results show that the two processes both can reach the desired removal efficiency of nitrogen and phosphorus with high sludge density.
