摘要
在渗滤液处理厂的二级A/O池+外置超滤处理工艺内应用短程硝化反硝化生物脱氮技术,进水C/N平均值为1.71的情况下,通过优化运行条件,使得短程工艺较全程工艺的需氧量减少26%;系统亚硝盐积累率达87%,AOB逐渐取代NOB成为优势菌种。
Short-cut nitrification and denitrification biological denitrification technology is applied in the secondary A/O pool+external ultrafiltration treatment process of leachate treatment plant.When the influent C/N average value is 1.71,by optimizing the operating conditions,The short-range process reduces the oxygen demand of the whole process by 26%;the system nitrite accumulation rate reaches 87%,and AOB gradually replaces NOB to become the dominant species.
