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.类似文献/References:[1]刘常青,陈琬,曾艺芳,等.SARD与CSTR反映器半持续发酵产氢能力对照[J].中国给水排水,2018,34(21):7.　LIU Chang qing,CHEN Wan,ZENG Yi fang,et al.Hydrogen Production Capacity of Semi continuous Fermentation of SARD and CSTR Bio hydrogen Production Reactor[J].China Water & Wastewater,2018,34(21):7.[2]李胜海,陈思,白静,等.山地城市市政道路低影响开辟雨水系统设想与建立[J].中国给水排水,2018,34(20):60.　LI Sheng hai,CHEN Si,BAI Jing,et al.Design and Construction of Stormwater Systems for Low-Impact-Development of Municipal Roads in Mountainous City[J].China Water & Wastewater,2018,34(21):60.[3]颜莹莹,梁远,沙雪华,等.新冠肺炎疫情下关在削减污泥中病原体的思虑[J].中国给水排水,2020,36(6):22.[4]郭波,田瑜,范晨,等.绿色纳米铁/H2O2联用两性脱水剂调度污泥研究[J].中国给水排水,2020,36(13):62.　GUO Bo,TIAN Yu,FAN Chen,et al.

  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 t����APPime, 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.
