生物脱氮工艺在焦化废水处理中的应用

Biological Denitrogenation Craft in Coking-Plant Wastewater Processing Application

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工艺、A-A/O工艺和缺氧-好氧-接触氧化工艺的工艺流程和运行效果,给出了焦化废水生物脱氮效果的影响因素。

The principle of biological denitriflcation was introduced in this paper. Emphasis on introducing advanced effective A/O crafts, A - A/O processes and anaerobic biochemical reduction - aerobic biochemical oxidation- contact biological degradation processes , and operational effectiveness of the processes. It gives the factors which affect the＇ biological denitrification.
