摘要:研究了序批式反應(yīng)器（SBR）中，不同濃度全氟辛酸（PFOA）對(duì)好氧顆粒污泥（AGS）系統(tǒng)的影響機(jī)制。結(jié)果表明，隨著PFOA濃度的增加（0、0.05、0.5和2.0 mg/L），系統(tǒng)中的污泥濃度和生物量明顯減少，并伴有顆粒增大和沉降性能下降的現(xiàn)象。當(dāng)PFOA≥0.5 mg/L時(shí)，AGS對(duì)TP、TN的去除受到明顯抑制，去除率較空白組分別降低了11.01%、9.81% （PFOA=0.5 mg/L）和18.57%、14.96% （PFOA=2.0 mg/L）。水中PFOA主要通過(guò)污泥吸附作用去除，而受生物降解影響甚微。污泥通過(guò)增加胞外聚合物（EPS）的分泌以抵御毒性，三維熒光光譜顯示EPS中代表色氨酸和酪氨酸類(lèi)物質(zhì)的峰熒光強(qiáng)度增加，而芳香蛋白色氨酸類(lèi)物質(zhì)可能與PFOA發(fā)生反應(yīng)。高通量測(cè)序結(jié)果表明，在PFOA≥0.5 mg/L的脅迫下，除磷菌Pseudomonas和Acinetobacter的相對(duì)豐度分別從空白組的5.92%、10.69%降至3.86%、6.56% （PFOA=0.5 mg/L）和3.49%、3.49% （PFOA=2.0 mg/L），反硝化功能菌Thermomonas、Flavobacterium和Gemmatimonass豐度亦顯著下降，顆粒污泥的好氧吸磷、硝化和反硝化過(guò)程受到明顯抑制。綜合分析暴露于PFOA環(huán)境中AGS各項(xiàng)性能和微生物群落的響應(yīng)變化，提出了PFOA對(duì)AGS系統(tǒng)的抑制濃度為0.5 mg/L。
Abstract:The effect of different concentrations of perfluorooctanoic acid (PFOA) on aerobic granular sludge (AGS) in a sequencing batch reactor (SBR) was investigated. 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.
