不同填料对减缓A/O-HMBR系统膜污染的试验研究

Experiment Study of Different Filler Mitigation on Membrane Fouling of A/O-HMBR

为了考察投加悬浮填料与组合填料的2组缺氧/好氧-复合式膜生物反应器(A/O-HMBR)系统减缓膜污染情况,对2组反应器的跨膜压差(TMP)、膜面胞外聚合物(EPS)平均含量、填料表面EPS平均值以及各种膜阻力进行比较,结果表明投加组合填料相对投加悬浮填料更有利于降低A/O-HMBR系统膜污染速率。

In order to observe the membrane fouling cases of two groups of A/O-HMBR system added with suspended packing and combined packing,the transmembrane pressure difference（TMP） and the average content of extracellular polymeric substances（EPS） of membrane and the average content of packing surface EPS and various membrane resistances were compared. The results showed that the effect of reducing membrane fouling rate of combined packing was better than the suspended packing.
