摘要
富氧曝气活性污泥法是当前废水生化处理较先进方法之一,各国都在推广应用。但它的生化机理及污泥性能研究报导甚少。本文通过对富氧曝气与空气曝气的生物相及污泥活性较系统地对比实验研究,得出富氧曝气在上述方面均优于空气曝气,并从机理上进行了初探。
Activatet sludge process with high purity oxygen aeration is one of more advanced systems for wastewater treatment and has been used in many contries. But so far there are a few reports about the biochemical mechanism and sludge characteristics of this process. Using parallel experiments, the microbial community and the activity of sludge in traditional activated sludge process and in high purity oxygen aeration process are compared. The results show that high purity aeration process is better than traditional activated sludge process. The mechanism of high purity oxygen aeration process is also discussed in this article.
