文章摘要

The influence of emulsified oil, suspended solids, Fe3+, Fe2+, cationic water clarifier and sulfate-reducing (SR) bacteria on the aggregation behavior of residual hydrophobic modified polyacrylamide in treated oily wastewater from polymer flooding was studied by fluorescence spectroscopy and dynamic light scattering. The result of I1/I3 showed that the polarity of hydrophobic microdomains increased, whereas the size of the hydrophobic microdomains may be decreased, where the value of I1/I3 represents the ratio of the intensity of peak I1 (374.0 nm) to that of peak I3 (385.0 nm) of the vibration fine structure of pyrene monomer emission in residual polymer solution. The results of the ratio of I1 at 48 h to I1 at 0 h (I1,48h/I1,0h) indicated that oil and cationic water clarifier could inhibit the aggregation to some extent, while Fe2+ and suspended solids were helpful for aggregation, and Fe3+ and SR bacteria had no significant influence on the aggregation of polymer.
