| 摘 要： | 根据旅游区公厕污水水质水量特征,采用常规A/O工艺以武汉市动物园公厕化粪池污水为实例进行研究.试验证明A/O工艺虽能有效去除水中COD,但NH 4-N的去除率较低,难以超过60%.针对此问题,本研究提出了该工艺的改进措施,将好氧段按功能分为二级,即碳氧化段和硝化段.试验结果表明,A/O工艺经改进后,在有效去除COD的同时,NH 4-N去除率由60%上升为80%以上.

| Abstract: | Conventional A/O process provided adequate COD removal yet only 60% removal of ammonia-nitrogen when it was employed for treating the septic tank effluent of public washrooms in Wuhan Zoo. Based on the wastewater characteristics, a two-stage aerobic treatment, consisting of the first stage of COD removal and the second stage of nitrification, was developed. The improved A/O process removed more than 80 % of ammonia-nitrogen in the raw wastewater. |
