| 摘 要： | 以热处理后的餐厨垃圾和市政污泥为底物, 采用高温两相厌氧发酵工艺, 在外加热源条件下, 研究不同进料负荷(OLR)对两相厌氧产氢、产甲烷系统的产气性能影响. 结果表明 随着产氢相OLR的增加, 系统平均VS产气率、氢气体积分数、容积产气率呈先升后降的趋势, 并在OLR为·(L·d)-1时取得最大值, 分别为·g-1、 45.61%和·(L·d)-1; 当产甲烷相OLR为·(L·d)-1时, 甲烷体积分数最大, 为49.54%, 当产甲烷相OLR为·(L·d)-1, 系统平均VS产气率和最大容积产气率最大, 分别为·g-1和·(L·d)-1, 且此时两相系统VS去除率与能量产率最高, 分别为65.37%和30.93kJ·L-1. 因此, 高温、高含固率餐厨垃圾协同市政污泥厌氧两相产氢产甲烷不仅能同时获得产量与体积分数均较高的氢气与甲烷, 而且能够有较高的VS去除率.

| Abstract: | Taking thermally treated kitchen waste and municipal sewage sludge as substrates and using a thermophilic two-phase anaerobic fermentation process, under the condition of external heating source, the effects of different feed loads (OLR) are investigated on gas production performance of two-phase anaerobic hydrogen production and methane production. The results indicate that, with the increase of OLR of hydrogen-producing phase, the average VS gas generation rate, hydrogen volume fraction and volume gas generation rate of the system increase first followed by decreasing. The maximum values are obtained at OLR=·(L·d)-1, which read ·g-1, 45.61% and ·(L·d)-1, respectively. When OLR of methanogenic phase is ·(L·d)-1, the content of methane climbs to the highest (49.54%). When OLR of methanogenic phase is ·(L·d)-1, the average gas production rate of VS and the maximum volume gas production rate of the system reach the highest (·g-1 and ·(L·d)-1, respectively). In addition, the removal rate and energy yield of the two-phase system VS are found to be at the highest, being 65.37% and 30.93kJ·L-1, respectively. Therefore, anaerobic two-phase hydrogen and methane production from thermophilic and high solid content kitchen waste combined with municipal sewage sludge can not only obtain hydrogen and methane with high yield and content, but also have a high VS removal rate. |
