ENHANCED METHANOGENESIS OF WASTE ACTIVATED SLUDGE FERMENTATION BY DOSING AN ALGINATE-DEGRADING CONSORTIUM

  • 摘要: 厌氧消化生产甲烷是实现剩余污泥(WAS)资源化的重要技术,水解阶段是WAS厌氧资源化的限速步骤。WAS中的酸性多糖(如藻酸盐和半乳糖醛酸等)能够与水中Ca2+等二价阳离子形成凝胶类物质,具有维持污泥结构并阻碍微生物水解的作用,被认为是结构性胞外聚合物的主要组分。首先利用藻酸盐为底物经过恒化器培养得到高活性的藻酸盐降解菌群(ADC)。结果表明:投加ADC菌群能够明显提高剩余污泥(WAS)厌氧消化的功能,即在接种比[m(ADC)∶m(VSS)]为0.03 g/g时,污泥的甲烷产量提高了53.6%。进一步分析表明,该菌群对WAS的几种典型有机成分(聚半乳糖醛酸、葡聚糖和酪蛋白等)均具有较好的厌氧降解能力。Illumina Miseq高通量测序结果表明该ADC菌群以拟杆菌属(Bacteroides,96.3%)为主。该成果为强化剩余污泥厌氧发酵产甲烷提供了一种新的微生物方法。
