摘要：
Effects of magnetic Fe3O4 nanoparticles (Fe3O4 NPs) on the decontamination performance and the EPS components of sludge were studied during short-term exposure experiments. Results showed that compared with the control, the COD removal efficiency reduced from 92.8% to 84.5% with the abrupt short-term addition of excessive Fe3O4 NPs. The content of TB-EPS increased from 64.8 mg/gVSS to 74.5 mg/gVSS. The absorption peak of amine in LB-EPS became sharp in the FTIR spectra. In the EEM spectra, the intensity of coenzyme F-420 peak in LB-EPS was slightly enhanced.
