摘要
提出了一种化工生产中废水处理的新工艺──Anoxic／Oxic（A／O）工艺。实验室研究结果表明，该工艺能通过硝化-反硝化作用使吉化混合化工废水中COD、NH3－N和TN同时得到有效降解，为废水达标排放提供了一条有效途径。
A new wastewater treatment process consisting of anoxic and oxic unit (A/O process) has been developed in this study for chemical plants wastewater. The experiment for chemical plants wastewater of JCGC carried out in a laboratory has proved this process to be an effective way for reducing COD. NH3-N and TN Simultaneously by nitrification and denitrification. By this way,parameters of the effluent including COD and NH3-N may meet the discharge standards issued by national EPA.
