联合NaOH和Ca(OH)2强化剩余污泥厌氧发酵生产挥发性脂肪酸OA北大核心CSCDCSTPCD
Enhanced volatile fatty acids production from waste activated sludge anaerobic fermentation using combined NaOH and Ca(OH) 2
以剩余污泥为研究对象,在序批式厌氧反应器中探究了NaOH和Ca(OH)2联合作用对污泥厌氧发酵产挥发性脂肪酸(VFA)的影响.结果表明,相较于NaOH单独发酵,NaOH和Ca(OH)2的联合作用能够进一步促进VFA的积累,且NaOH和Ca(OH)2的质量比例为50∶50时,VFA的最大积累量为286 mgCOD·g-1VSS.机理研究表明,NaOH和Ca(OH)2联合作用能够促进污泥溶解过程,并且溶解性COD(SCOD)的最大含量为3 650 m…查看全部>>
The combined effects of NaOH and Ca (OH)2 on the volatile fatty acids (VFA) production from sludge anaerobic fermentation were investigated in the anaerobic reactor with waste activated sludge as the research object.The results showed that the combined effect of NaOH and Ca(OH) 2 can further promote the accumulation of VFA and the mass ratio of NaOH and Ca(OH) 2 is 50 ∶ 50,the maximal accumulation of VFA was 286 mg COD · g-1 VSS.Mechanism studies suggested t…查看全部>>
