纯氧曝气在城市污水处理中的应用前景

摘要

Tbe paper introduced the working principle of the pure oxygen aeration technology. Because of pure oxygen pressure was higher than the air oxygen partial pressure, pure oxygen aeration can significantly improve the oxygen transfer rate. Combination of microporous aeration technology and oxygen aeration technology can significantly improve the sludge concentration and improve sludge settling performance when it was applied to open aeration tank. In additionally, due to the pure oxygen microporous hose aeration technology having the advantages of both small workshop area, and low productive cost, it's especially used for the improvement of existing activated sludge treatment plant.%文章介绍了纯氧曝气技术的工作原理。由于纯氧的压力高于空气中氧的分压，纯氧曝气可显著提高氧的转移速率。将微孔曝气和纯氧曝气的优点结合起来。应用于敞开曝气池，可显著提高污泥浓度和改善污泥沉降性能。此外，由于占地面积小、运行成本低，故特别适用于现有活性污泥处理厂的升级改造。
