    摘要
  • 摘要: 对酸碱-微波耦合预处理后不同EPS组分在污泥厌氧消化行为中扮演的角色进行研究，通过产甲烷潜能实验评价其甲烷转化性能。结果表明：酸碱-微波耦合预处理通过溶出胞内有机物和改变EPS的分布来影响污泥产甲烷行为。甲烷累积产量最优预处理条件为pH=10，微波500 W，预处理时间120 s。此时，预处理后溶解型胞外聚合物（S-EPS）中的溶解性化学需氧量（SCOD）浓度达到11460 mg/L，是对照组浓度的184.5%，累积甲烷产量为89.08 mL/g，较对照组增加59.9%。碱处理（pH=10和12）时，S-EPS对累积甲烷产量的贡献率分别达到了16.6%和30.4%，远高于松散结合型胞外聚合物（LB-EPS）与紧密结合型胞外聚合物（TB-EPS）。在48 d的厌氧消化过程中，S-EPS对产甲烷的贡献率在1~4 d内快速升高，随后缓慢持续下降。因此，酸碱-微波耦合预处理通过强化污泥S-EPS中的多糖、蛋白质等有机质的溶出，促进污泥甲烷化。
    Abstract: Extracellular polymeric substances (EPS) are the essential components of sludge, which influence sludge dewaterability and methane productivity. In this study, the roles played by different EPS fractions in methane production of sludge were investigated. Results demonstrated that combined acid-alkali microwave pretreatment dissolved the intracellular organic matters and changed the distribution of EPS, and furthermore enhanced methanogenesis. The optimal conditions were observed to be pH=10, 500 W microwave and 120 s, and then the concentration of soluble chemical oxygen demand (SCOD) in S-EPS reached 11460 mg/L, increased by 84.5% compared with the control. The accumulative methane production approached 89.08 mL/g-VS, whose increase rate was 59.9%. At pH=10, 12, the contribution of S-EPS to methane production accounted for 16.6% and 30.4%, respectively, much higher than LB-EPS and TB-EPS. During the anaerobic digestion process, the contribution of S-EPS rapidly increased in the first four days and then slightly and constantly decreased in the following days. Therefore, acid-alkali pretreatment combined with microwave accelerated the methane production of sludge by enhancing the release of polysaccharide and protein from sludge flocs into S-EPS fraction.
