- 摘要:
- 污泥與餐廚垃圾含有豐富有機(jī)質(zhì)，將其進(jìn)行生物產(chǎn)氫具有處理固體廢棄物和開發(fā)氫能的雙重意義。生物反應(yīng)器的高效啟動(dòng)是該技術(shù)的關(guān)鍵因素。采用SARD和CSTR反應(yīng)器并輔以血清瓶，以污泥和餐廚垃圾作為反應(yīng)基質(zhì)，考察不同運(yùn)行時(shí)間、投配比(回流比)下的氫氣濃度及比產(chǎn)氫速率，以確定各反應(yīng)器的最佳運(yùn)行條件并篩選出較優(yōu)的反應(yīng)器。結(jié)果表明，SARD和CSTR在10~15 h內(nèi)先后達(dá)到了50.34%和53.43%的氫氣濃度最大值，最大比產(chǎn)氫速率分別為18.09、?14.98 mL/?（gDS·h）。投配比為50%、進(jìn)料時(shí)間間隔為8 h是較理想的進(jìn)料方式。SARD與CSTR反應(yīng)器半連續(xù)運(yùn)行的比產(chǎn)氫速率在穩(wěn)定階段分別維持在4.40、2.37 mL/（gDS·h）左右。相比較而言，SARD的運(yùn)行效果優(yōu)于CSTR，且半連續(xù)運(yùn)行比批式運(yùn)行的效果更佳。
- Abstract:
- Sludge and food wastes are rich in organic matter, and can be used as the substrate of bio?hydrogen production, which has a double significance for solid waste treatment and development of hydrogen energy. How to start the reactor efficiently is the key factors. SARD (semi?continuous anaerobic rotary drum) and CSTR(continuous stirred tank reactor) were used as hydrogen production reactor to investigate the influence of operation time and reflux ratio by adding sludge and food wastes, and analyzing hydrogen concentration and specific hydrogen yield. The results indicated that the hydrogen concentration reached the maximum value of 50.34% and 53.43% after 10-15 h in SARD and CSTR, respectively; the maximum specific hydrogen yield was 18.09 mL/(gDS·h) and 14.98 mL/(gDS·h) respectively. The better feeding mode was 50% adding ratio and interval 8 h. The specific hydrogen yields of SARD and CSTR were stable at 4.40 mL/(gDS·h）and 2.37 mL/(gDS·h) respectively. In comparison, semi?continuous operation was better than batch one, and SARD was better than CSTR.
