چکیده
|
The effect of salinity on the membrane fouling characteristics was investigated in the intermittently aerated membrane bioreactor (iambr). five different salinity loadings were set from 0 to 35 g·l-1 (referring to nacl),respectively. the removal of total organic carbon (toc) and ammonia-nitrogen (nh4+n) was gradually decreased with increasing salinity. the variation of membrane filtration resistance,particle size distribution (psd),extracellular polymeric substances (eps),soluble microbial products (smp),and relative hydrophobicity (rh) analysis revealed that salinity has a significant effect on sludge characteristics in iambr. the results also indicated that the membrane fouling is often caused by the integration of sludge characteristics in saline wastewater. © 2014 kang xie et al.
