With the increase of PFOA concentration (0 mg/L, 0.05 mg/L, 0.5 mg/L and 2.0 mg/L), the sludge concentration and biomass in the system decreased significantly, the particle size increased, and the settling performance decreased. When the concentration of PFOA was greater than or equal to 0.5 mg/L, it had obvious inhibitions on the removal of TP and TN. Compared with the blank group, the removal rates of TP and TN were decreased by 11.01% and 9.81% respectively when the concentration of PFOA was 0.5 mg/L, and 18.57% and 14.96% respectively when the concentration of PFOA was 2.0 mg/L. PFOA was mainly removed from water by sludge adsorption, while biodegradation had little effect on it. The sludge resisted the toxicity by secreting more extracellular polymer substances (EPS). Three-dimensional fluorescence spectra showed that the peak fluorescence intensity which represented tryptophan-like and tyrosine?like substances in EPS increased, and aromatic protein tryptophan substances in EPS might react with PFOA. High-throughput sequencing results showed that the relative abundance of Pseudomonas and Acinetobacter in the blank group decreased from 5.92% and 10.69% to 3.86% and 6.56% respectively when the concentration of PFOA was 0.5 mg/L, and 3.49% and 3.49% respectively when the concentration of PFOA was 2.0 mg/L. The abundance of Thermomonas, Flavobacterium and Gemmatimonass also decreased significantly, and the aerobic phosphorus absorption, nitrification and denitrification processes of granular sludge were significantly inhibited. After a comprehensive analysis of the changes in the properties of aerobic granular sludge and the response of the microbial community under PFOA exposure, the inhibitory concentration of PFOA on aerobic granular sludge system was proposed to be 0.5 mg/L.类似文献/References:[1]张莹,王昌稳,李军,等.投加微粉强化低浓度糊口污水活性污泥好氧颗粒化[J].中国给水排水,2018,34(21):12.
