【摘要】：通過批次實(shí)驗(yàn)研究溫度對餐廚垃圾自由厭氧發(fā)酵(不控制pH)性能的影響�？疾炝耸覝�(25℃),中溫(35℃)和高溫(55℃)條件下發(fā)酵基質(zhì)的降解程度和有機(jī)酸的產(chǎn)量以及組成情況。結(jié)果表明,盡管高溫條件下顆粒態(tài)有機(jī)物有最快的水解速率,但室溫條件下有機(jī)酸濃度卻達(dá)到了最大值(8.85 g COD·L~(-1));乳酸和乙酸是自由發(fā)酵過程中最主要的有機(jī)酸,室溫下乳酸和乙酸的含量分別為總有機(jī)酸的72.86%和25.11%,而中溫和高溫時(shí)乳酸和乙酸的含量比值均在43.6%~50%之間。實(shí)驗(yàn)表明,自由發(fā)酵條件下,最佳的水解酸化溫度是25℃。
