A^2/O生物脱氮工艺在焦化废水处理中的应用

Application of A^2/O Biological Denitrification Technology for Coking Waste Water Treatment

介绍了生物法处理焦化废水工艺的改进和对比,总结并讨论了影响去除COD、NH3-N的主要因素:进水水质、回流比、C/N比、溶解氧、pH值和温度等。生产实践证明,A2/O生物脱氮工艺对于处理焦化废水是有效的,可使COD、NH3-N等指标达到有关国标的二级标准。

The existing activated sludge process was modified into the A^2/O biological denitrification process for coking waste water treatment. Several factors that affect the removal of COD and NH3-N were discussed. Through the application in practice, it is concluded that the A^2/O biological denitrification process is efficient for coking waste water treatment.
