The modified resin is used as a multifunctional biological carrier to treat phenolic wastewater (PW) in an anaerobic fluidized bed microbial fuel cell (AFB-MFC). First, the modified resin was prepared, and the conductive polyaniline (PANI) was polymerized in situ on the surface and pores of the macroporous adsorption resin (MAR) to prepare the modified resin composite material (MAR/PANI). A series of modified resins with different mass ratios of resin and aniline were prepared. The modified resins were characterized by Fourier-transform infrared spectroscopy, scanning electron microscopy (SEM), specific surface area, and pore structure analysis. Materials Studio (MS) software was used to study the internal interaction forces of PANI and MAR, and the molecular dynamics simulation method was used to analyze and calculate the cohesive energy density. The simulation results are qualitatively consistent with the experimental data. The sorption module in the MS software was used to study the adsorption behaviour of the modified resin to the organic components in the wastewater, and the adsorption mechanism was explained on the atomic scale. When the modified resin with m (MAR):m(An) = 1:0.6 was used in the AFB-MFC, the chemical oxygen demand removal efficiency of wastewater was increased by 26.2%–88.90%, the voltage was increased by 98.46%–489.2 mV, and power density was increased by 303.28%–131.43 ± 0.17 mW/m2.

聚苯胺-大孔吸附树脂多功能载体厌氧流化床微生物燃料电池处理含酚废水
该改性树脂用作多功能生物载体，在厌氧流化床微生物燃料电池（AFB-MFC）中处理含酚废水（PW）。首先制备改性树脂，将导电聚苯胺（PANI）原位聚合在大孔吸附树脂（MAR）的表面和孔内，制备改性树脂复合材料（MAR/PANI）。制备了一系列不同树脂与苯胺质量比的改性树脂。通过傅里叶变换红外光谱、扫描电子显微镜（SEM）、比表面积和孔结构分析对改性树脂进行了表征。利用Materials Studio（MS）软件研究了PANI和MAR的内相互作用力，并采用分子动力学模拟方法分析计算了内聚能密度。模拟结果与实验数据定性一致。利用MS软件中的吸附模块研究了改性树脂对废水中有机成分的吸附行为，并在原子尺度上解释了吸附机理。当m(MAR):m(An)=1:0.6的改性树脂用于AFB-MFC时，废水化学需氧量去除效率提高了26.2%~88.90%，电压提高了98.46% –489.2 mV，功率密度增加303.28%–131.43 ± 0.17 mW/m2 .
