| 摘 要： | A-A-O工艺,即厌氧-缺氧-好氧组合工艺,由三段生物处理装置组成。通过细菌的生物化学作用,将废水中的氨氮经硝化和反硝化反应转变成无害的N2而脱除的过程,能较好的去除焦化废水中NH3-N,COD及酚。A-A-O工艺在处理焦化废水的过程中的影响因素是溶解氧、温度、pH或碱度、有机物与氨氮比值及泥龄等。虽然影响因素较多,但A-A-O工艺仍是目前国内较先进的处理焦化废水的生物脱氮工艺。

| Abstract: | A-A-O process, that is anaerobic - anoxic - aerobic combined process, from three sections of bio-processing unit. By bacteria bio-chemical effect of ammonia nitrogen wastewater by nitrification and denitrification into harmless N2 and the removal process can be better to remove the coking wastewater NH3-N, COD and phenol. A-A-O Technology in Treatment of Coking Wastewater process factor is dissolved oxygen, temperature, pH or alkalinity, organic matter and ammonia nitrogen ratio and sludge age and so on. Although many factors influence, but the A-A-O process is still more advanced treatment of domestic coking wastewater biological nitrogen removal process. |
