摘要
针对传统活性污泥法生物脱氮除磷功能较差 ,中试试验采用投加悬浮填料增加其脱氮能力。试验结果表明 ,在原水力停留时间不变的条件下 ,投加悬浮填料 ,不仅系统硝化效果明显 ,而且总氮去除率也能得到显著提高。投加悬浮填料增加传统活性污泥法的脱氮功能是经济。
The biological nitrogen and phosphorous removals of activated sludge process are very limited.In order to enhance the denitrification capability of the system,suspended fillers are added to the pilot-scale reactor which remains the same HRT as the on-site activated sludge process.The result of the experiment shows that not only the nitration of the system but also the removal of total nitrogen are improved sharply,which manifests that the method is economical and feasible.
