摘要
针对目前国内大部分焦化厂排放的废水中NH3-N和CODCr超标的问题，介绍一种在普通活性污泥法基础上改进的焦化废水处理工艺O-A—O（好氧-兼氧-好氧）工艺，该工艺对焦化废水处理具有明显效果．是解决焦化废水污染的有效途径。
To deal with excess NH3-N and CODcr in wastewater of internal coking plants an O-A-O tcchnology was introduced in this article, which was improved on the hasis of ordinary active sludge process. This technology has an obvious effect on the treatment to coking wastewater, and it is the best way to solve the problem of coking wastewater.
