Abstract：BPA simulated wastewater was treated by Sequencing Batch Bioreactor( SBR) to investigate the effects of different BPA wastewater treatment methods on sludge acute toxicity and protein expression. The results showed that when the influent BPA concentration was 40 mg/L, the sludge activity in the BPAimpacted SBR was significantly inhibited, and the mass concentration of the effluent COD was significantly higher than that of the SBR gradually acclimated by the influent BPA. With the extension of running time, the mass concentration of BPA in the aqueous phase and mud phase increased first and then decreased until it was completely degraded. In the whole SBR operation, sludge and EPS acute toxicity in the SBR impacted by the BPA were both higher than that of the gradually acclimated SBR, but EPS acute toxicity had little effect on the acute toxicity of sludge; The protein expression in the sludge treated with different methods of BPA wastewater showed significant differences. The concentration of BPA and the way of degrading BPA had a significant effect on the protein expression in the sludge.
