Research on the optimum backwashed cycle and the backwashed methods of the biological aerated filtrated reactor
曝气生物滤池最佳反冲洗周期及反冲洗方式研究
TMP of all the six membranes recovered well after backwashed periodically. It is shown that it is possible to pretreat high turbidity seawater by the ultrafiltration.
不同类型的超滤膜通过周期性的反洗可以使跨膜压差有较好的恢复率，这表明了超滤作为高浊度海水反渗透预处理是可行的。
Biomass and microbial activity in backwashed biofilter
生物滤池反冲洗过程中生物量和生物活性的分析
If the lower section of the first filter which the loading was higher was backwashed singly, the requirement of backwashing water and gas should be saved 6.7% and 16.7%, respectively, and the stability of whole procee should be enhanced.
将一级上向流滤池下部高负荷段设置单独的反冲洗，不仅可以节省6.7%的用水量和16.7%的供气量，而且有利于提高系统稳定性。
