The occurrence and removal of ten bisphenol analogues (BPs) in municipal wastewater treatment plants (WWTPs) and laboratory scale activated sludge bioreactor (ASBR) were studied. All targeted BPs except for tetrachlorobisphenol A (TCBPA) were detected in the four WWTPs (W1, W2, W3 and W4) in the ng/L and ng/g dry weight range in wastewater and activated sludge, respectively, indicating that in addition to BPA, the BPA substitutes were widely used in our daily life and industrial production. Discrepant results regarding the removal efficiencies of BPs by different wastewater treatment processes were obtained. The removal rates were 55.6%, 24.4%, -10.1%, 71.4%, 38.9%, 58.0%, 39.1% and 6.4% in W1, 65.4%, 32.8%, 44.7, -13.5%, 20.1%, -29.6%, -25.1% and 99.4% in W2, 11.6%, 48.8%, 38.9%, 22.0%, 99.0%, -29.2%, -56.5% and 32.6% in W3, 33.9%, 30.5%, 17.4%, -47.6%, 62.9%, 83.0%, 4.4% and -4.3% in W4, for BPA, BPB, BPE, BPF, BPS, BPZ, BPAF and BPAP, respectively. The removal of ten targeted BPs in lab-scale continuous flow conventional ASBR and the key factors were investigated. The simulated laboratory-scale ASBR were highly effective in removing BPA, BPB, BPE, BPF, BPM and BPS with removal efficiencies of >94.3%, while BPZ, BPAP, BPAF and TCBPA were recalcitrant to elimination in the stimulated bioreactor with removal efficiencies of 71.3 ± 13.7%, 55.1 ± 21.2%, 47.4 ± 9.5% and 45.3 ± 16.6%, respectively. Protonation, hydrophobicity and molecular features of BPs were critical for their elimination in wastewater.
研究了十种双酚类似物（BPs）在城市污水处理厂（WWTPs）和实验室规模的活性污泥生物反应器（ASBR）中的产生和去除情况。在四个 WWTP（W1、W2、W3 和 W4）中，除四氯双酚 A（TCBPA）外，所有目标 BPs 均以 ng/L 和 ng/g 干重的范围在废水和活性污泥中被检出，这表明除 BPA 外，BPA 替代品在我们的日常生活和工业生产中被广泛使用。不同污水处理工艺对 BPs 的去除效率存在差异。在 W1 中，BPA、BPB、BPE、BPF、BPS、BPZ、BPAF 和 BPAP 的去除率分别为 55.6%、24.4%、-10.1%、71.4%、38.9%、58.0%、39.1%和 6.4%；在 W2 中，BPA、BPB、BPE、BPF、BPS、BPZ、BPAF 和 BPAP 的去除率分别为 65.4%、32.8%、44.7、-13.5%、20.1%、-29.6%、-25.1%和 99.4%；在 W3 中，BPA、BPB、BPE、BPF、BPS、BPZ、BPAF 和 BPAP 的去除率分别为 11.6%、48.8%、38.9%、22.0%、99.0%、-29.2%、-56.5%和 32.6%；在 W4 中，BPA、BPB、BPE、BPF、BPS、BPZ、BPAF 和 BPAP 的去除率分别为 33.9%、30.5%、17.4%、-47.6%、62.9%、83.0%、4.4%和-4.3%。考察了实验室规模连续流常规 ASBR 中十种目标 BPs 的去除情况及其关键因素。模拟实验室规模的 ASBR 对 BPA、BPB、BPE、BPF、BPM 和 BPS 的去除非常有效，去除效率大于 94.3%，而 BPZ、BPAP、BPAF 和 TCBPA 在模拟生物反应器中难以消除，去除效率分别为 71.3±13.7%、55.1±21.2%、47.4±9.5%和 45.3±16.6%。BP 的质子化、疏水性和分子特征对其在废水中的消除至关重要。
