摘要:以山地城市污水處理廠未添加化學(xué)調(diào)理劑的濃縮污泥為原料，通過設(shè)置200、220、240、260 ℃這4個反應(yīng)溫度和2、4、6 h這3個反應(yīng)時間共12組實驗，探究反應(yīng)溫度和反應(yīng)時間對污泥水熱炭化固相和液相產(chǎn)物的影響。結(jié)果表明，隨著反應(yīng)溫度和時間的增加，污泥水熱炭產(chǎn)率從69.32%（200 ℃-2 h）降至59.49%（260 ℃-6 h），同時水熱炭中的官能團O—H、C—H和C=C逐漸降解，H/C值和O/C值（物質(zhì)的量之比）減小，水熱炭的脫羧和芳構(gòu)化反應(yīng)增強。整體而言，升高反應(yīng)溫度比延長反應(yīng)時間對污泥水熱炭化的影響更大。BMP（產(chǎn)甲烷潛力）實驗表明，隨著反應(yīng)溫度的升高，液相產(chǎn)物中難降解有機物含量增加，而且其中的苯酚和呋喃衍生物等復(fù)雜有機物對厭氧反應(yīng)具有抑制作用，累積甲烷產(chǎn)量隨之降低。隨著反應(yīng)溫度和時間的增加，C含量呈上升趨勢，而H、O和N含量反之，水熱炭的高位熱值（HHV）、能量密度和能量產(chǎn)率均低于污泥原料。污泥的高含砂量對水熱炭的元素含量和熱值影響顯著，建議對污泥含砂量進行有效控制。
Abstract:Effects of reaction temperature and time on solid and liquid hydrothermal carbonization products of the concentrated sludge without adding chemical conditioner in a wastewater treatment plant of a mountainous city were investigated.Twelve groups of experiments were set up by setting four reaction temperatures (200 ℃, 220 ℃, 240 ℃ and 260 ℃) and three reaction times (2 h, 4 h and 6 h). With the increase of reaction temperature and time, the yield of sludge-based hydrothermal charcoal decreased from 69.32% (200 ℃ and 2 h) to 59.49% (260 ℃ and 6 h), the functional groups of O—H, C—H and C=C were gradually degraded, H/C value and O/C value decreased, and the decarboxylation and aromatization reactions of hydrothermal charcoal were enhanced. Overall, increasing reaction temperature had a greater impact on hydrothermal carbonization of sludge than extending reaction time. Biochemical methane potential (BMP) experiments indicated that the content of refractory organics in liquid products increased with the increase of reaction temperature,complex organics such as phenol and furan derivatives inhibited the anaerobic reaction, and the cumulative methane production decreased accordingly.With the increase of reaction temperature and time, the carbon content showed an upward trend, while the contents of hydrogen, oxygen, and nitrogen decreased, and the high heat value (HHV), energy density, and energy yield of hydrothermal charcoal were all lower than those of the raw sludge. The high sand content of sludge had a significant influence on the element content and HHV of hydrothermal charcoal. It was suggested to control the sand content of sludge effectively.
