| 摘 要： | 焦化废水生物处理存在的主要问题是系统运行稳定性差、难降解有机物和氨氮去除率低.为此,采用新型好氧-缺氧-好氧生物(O1-A-O2)工艺处理实际焦化废水.实验结果表明,该系统在处理焦化废水过程中运行稳定,系统中O1是有机污染物去除的主要处理单元,而O2是氨氮去除的主要处理单元.系统COD(Chemical Oxygen Demand)总去除率为86%,NH+4 -N去除率为61.3%,强化了普通活性污泥工艺处理效果.

| Abstract: | The main disadvantages of biological treatment for coking wastewater are not effective in removing the refractory organics and NH 4N,and poor stability.Aerobic(O1)Anoxic(A)-Aerobic(O2) biological process was put forward for the wastewater treatment.The experiments showed that the new system isstable in operation.The COD and NH 4N are mainly removed in the first and second aerobic unit respectively.The COD and NH 4-N removals of the O1-AO2 systems are more than 86% and 61.3% respectively and the efficiency of conventional activated sludge process is impro Ded for the wastewater treatment. |
