无泡曝气技术在水处理中的研究进展

Research on Bubbleless Oxygenation Technology in Water Treatment

无泡曝气技术是一种很有发展前景的新型的供氧方式,具有传氧效率高、无泡沫形成、设备体积小、能耗低等优点,但由于曝气材料的成本高等原因并未大规模应用。目前对该技术的研究主要集中在充氧性能,反应器处理效果以及所形成的生物膜的研究,在曝气材料及与其他水处理工艺的结合方面都有待于进一步发展。

Bubbleless Oxygenation technology is a promising oxygen aeration technology,and it has the advantages of high oxygen mass transfer rate,no foam formation,small size of equipment and low energy exhausting,but it isn＇ t applied in large-scale because of the high cost of membrane material.At present,research on the Bubbleless Oxygenation technology focused on oxygenation properties,the treatment effect of reactor and biofilm it forms,the future development of this techonology will focus on oxygenation materials and combining with other water treatment reactor.
