| 摘 要： | 在以焦炭为填料的生物滴滤塔对挥发性脂肪酸臭气的处理研究中考察了空床停留时间、臭气浓度、体积负荷以及进气温度等参数对净化效果的影响。结果表明，空床停留时间较长时对臭气降解有利。在停留时间超过97 s时，能实现完全降解；此外，净化率随臭气浓度和体积负荷的不断增加呈先增加后降低的趋势。当臭气浓度为24.29 mg/m3即臭气的体积负荷为3 g/（m3·h）时，去除率约为96%；当臭气浓度增至1 345.74 mg/m3即体积负荷增至18 g/（m3·h），去除率达100%；然而，当臭气浓度增至4 934.38 mg/m3即体积负荷增至66 g/（m3·h）时，去除率降至73.1%。另外，进气温度对净化率也有一定程度影响。当进气温度较低时，净化效率相对较高。

| Abstract: | A biotrickling reactor packed with coke was performed to evaluate the effect of the empty bed residence times, odor concentration, mass loadings and inlet gas temperatures on the biodegradation of volatile fatty acids. The results showed that a longer residence time was beneficial to the biodegradation of volatile fatty acids and removal efficiency of 100% was obtained using a residence time of 97 s. Furthermore, the removal efficiency exhibited a increasing and then a decreasing trend with the increase of odorous concentration and mass loadings. The removal efficiencies of 96%, 100% and 73.1% were achieved at an odorous concentration of 224.29 mg/m3 with mass loadings of 3 g/(m3·h), an odorous concentration of 1 345.74 mg/m3 with mass loadings of 18 g/(m3·h) and an odorous concentration of 4 934.38 mg/m3 with mass loadings of 66 g/(m3·h), respectively. In addition, the removal efficiency is related to the inlet gas temperatures. When the inlet gas temperature was lower, the removal efficiency was relatively high. |
