Biofilm response and removal via the coupling of visible-light-driven photocatalysis and biodegradation in an environment of sulfamethoxazole and Cr(Ⅵ)
文献摘要：
The widespread contamination of water systems with antibiotics and heavy metals has gained much attention.Intimately coupled visible-light-responsive photocatalysis and biodegradation(ICPB)provides a novel approach for removing such mixed pollutants.In ICPB,the photocatalysis products are biodegraded by a protected biofilm,leading to the mineralization of refractory organics.In the present study,the ICPB approach exhibited ex-cellent photocatalytic activity and biodegradation,providing up to～1.27 times the degra-dation rate of sulfamethoxazole(SMX)and 1.16 times the Cr(Ⅵ)reduction rate of visible-light-induced photocatalysis.Three-dimensional fluorescence analysis demonstrated the synergistic ICPB effects of photocatalysis and biodegradation for removing SMX and reduc-ing Cr(Ⅵ).In addition,the toxicity of the SMX intermediates and Cr(Ⅵ)in the ICPB process significantly decreased.The use of MoS2/CoS2 photocatalyst accelerated the separation of electrons and holes,with·O2 and h+attacking SMX and e-reducing Cr(Ⅵ),providing an ef-fective means for enhancing the removal and mineralization of these mixed pollutants via the ICPB technique.The microbial community results demonstrate that bacteria that are conducive to pollutant removal are were enriched by the acclimation and ICPB operation processes,thus significantly improving the performance of the ICPB system.
