| Abstract: | This research investigates the ability and effect of nanoscale zero-valent iron (NZVI) particles in inactivating sulfate-reducing bacteria; and conjectures the mechanism through observing transformation of SRB and NZVI. According to the research results, when adding 0, 1, 2, 5, and 10 mg/mL NZVI to the injection water, the inactivating rate of SRB would be 0, 75.6%, 90.0%, 99.9% and 99.9%. The dyeing and ESEM results show that NZVI adsorbs closely to the SRB cell when inactivating SRB, and it is oxidated on the surface of the bacteria cells. 5 mg/mL NZVI kills SRB greatly and the inhibition may mainly through coating the cells, inhibiting cell proliferation, rather than destroying the cellular structure. |
