摘要
A^2/O(A/O)生物脱氮工艺在太原市北郊污水净化厂工艺改造中得到成功的应用,不增设处理构筑物,对原生物吸附——再生工艺进行改建,氨氮去除率>90％,处理出水供太原钢铁公司作为冷却水的补充水,系统排出的剩余污泥量也明显减少。工程改建费50万元,每天可回收1.0万m^3回用水。
The application of A2/O (A/O) biological denitrification process in the reformation of The Northern Suburb Sewage Purification Plant in Taiyuan is successful. The original bioadsorption - regeneration has been reformed without any additional structures,the removal efficiency of NH4 -N is enhanced to 90% and higher. Effluent is reused as make-up water of cooling water in Taiyuan Iron and Steel Corporation, and the quantity of excess sludge is reduced apparently. The expense of the engineering reformation is 0. 5 million RMB. but 10000 m3/d reused water is obtained.
