摘要
叙述了焦化废水生物脱氮的原理。着重介绍了先进有效的A/O、A—A/O和缺氧—好氧—接触氧化的工艺流程及运行效果,指出了影响焦化废水生物脱氮效果的因素。
The principle of biological denitrogenation in the coking - plant wastewater was explained in this paper. The advanced effective A/O, A-A/O process and anaerobic - aerobic biochemical and oxidation - contact biological degradation process and operational effectiveness were emphatically introduced. The factors that affected the biological denitrogenation in the coking - plant wastewater were pointed out.
