  • 摘要: 以人工配水启动SBR，逐步提高进水苯酚浓度，探究好氧颗粒污泥对苯酚的降解能力，同时分析苯酚对好氧颗粒污泥特性的影响。经过55 d的运行，进水苯酚浓度逐渐增到3 000 mg/L，苯酚、COD及NH4+-N去除率分别达到了98.33%、97.27%和57.58%，好氧颗粒污泥表现出对苯酚的良好的去除能力。扫描电镜照片显示投加苯酚后的颗粒污泥表面更加光滑，结构更为紧凑。胞外聚合物红外光谱分析表明投加苯酚前后好氧颗粒污泥EPS的主要组分没有明显改变。苯酚毒性刺激了颗粒污泥分泌更多胞外聚合物，胞外聚合物中多糖含量由初始的12.70 mg/g VSS增加到35.17 mg/g VSS，蛋白含量由4.93 mg/g VSS增加到8.01 mg/g VSS。投加苯酚后的污泥粒径明显增大，主要污泥粒径由0.5~2.0 mm增大到2.0 mm以上。
    Abstract: The SBR started up with synthetic water,the ability to degrade phenol by aerobic granular sludge and the effect of phenol on aerobic granular sludge characteristics were investigated by increasing the influent phenol concentration gradually. After 55 days of operation, the influent phenol concentration reached 3 000 mg/L, while removal efficiencies of phenol,COD and NH4+-N were 98.33%,97.27% and 57.58%, respectively and aerobic granular sludge showed an excellent phenol removal ability. The scanning electron microscope image illustrated the granular sludge surface becomes more smoother and the granular has a more compact structure after adding phenol. The infrared spectrum analysis of extracecellular polymers (EPS) showed that the components of EPS have no obvious change after adding phenol.The phenol toxicity stimulated the granular sludge to secrete more EPS, the polysaccharide in EPS increased from 12.70 mg/g VSS to 35.17 mg/g VSS while the protein in EPS increased from 4.93 mg/g VSS to 8.01 mg/g VSS. Sludge particle size increased significantly for the phenol addition, the main particle size increased from 0.5~2.0 mm to above 2.0 mm.
