摘要
在试验条件相同的情况下,进行了序批式膜生物反应器SBBR与SBR的清水充氧试验,氧传质特性比较研究结果表明:当曝气强度为0.3m3/h时,SBBR的(KLa)20和Eo2值均为SBR的1.59倍。SBBR具有更好的氧传质能力和更高的氧转移效率。
Aeration tests of clean water with SBBR and SBR were made under the same testing conditions.It is shown by the results of a comparative study of oxygen mass transfer performances that when the intensity of the aeration was0.3m 3 /h the values of(K L a ) 20 and Eo 2 of SBBR were respectively1.59times the values of the(K L a ) 20 and Eo 2 of SBR and that SBBR has a better oxygen mass transfer capability and a higher oxygen transfer efficiency.
