摘　　要：研究了不同脱毒材料和处理方式对热解液中内醚糖及紫色光合菌利用热解液的影响.实验结果表明,脱毒处理能显著改善紫色光合菌对热解液的利用效率,不同的脱毒材料对热解液中的内醚糖吸附程度有较大的差异.以氢氧化钙和活性炭联用处理后,紫色光合菌对热解液的利用效果最好,对内醚糖的利用率在培养的第4d即达到77.7%,培养6 d对热解液的利用率达到94.1%,远高于未脱毒处理时的利用效率(61.9%,14 d).几种脱毒处理方式中,以氢氧化钙处理时对内醚糖的吸附最少(15.1%),而以717阴离子交换树脂处理时对内醚糖的吸附量最高(68.8%).Effect of different detoxification materials and treatments on the absorption of levoglucosan in pyrolysis liquid and utilization of pyrolysis liquid by Photosynthetic bacteria are studied. The results show that it greatly promotes the utilization of pyrolysis liquid after detoxification. Moreover, absorptions of levoglucosan in pyrolysis liquid are greatly different after treatment with different detoxification materials. Utilization of pyrolysis liquid is optimal by using activated carbon add Ca（OH）2 treatment method. The results show that utilization rate are 77. 7% and 94. 1% after cultured 4 d and 6 d respectively,which are much higher than those before detoxification（61. 9%,14 d）. In those treatment methods, absorption of levoglucosan is the lowest by Ca（OH）2 treatment method（15. 1%）,while 717 anion-exchang resin treatment method is hightest（68. 8%）.
