| 摘 要： | 在常温条件下,采用生物滴滤塔处理模拟甲硫醚废气,考察了气体空床停留时间(EBRT)、容积负荷、喷淋密度及营养液pH对生物滴滤塔性能的影响。实验结果表明:当EBRT为90 s、进气甲硫醚质量浓度为150 mg/m~3、喷淋密度为0.65 m~3/(m~2·h),营养液pH为6.8时,甲硫醚去除率为90%;容积负荷高于15 g/(m~3·h)时,对生物滴滤塔的性能产生抑制作用;EBRT为90 s及60 s时,最佳喷淋密度分别为0.56~0.65 m~3/(m~2·h)及0.65~0.75 m~3/(m~2·h);降解甲硫醚的微生物对pH的变化较敏感,最适营养液pH为6~7。

| Abstract: | The simulated waste gas containing dimethyl sulphide was treated in a biotrickling filter at room temperature. The factors affecting the performance of the biotrickling filter were studied. The experimental results showed that：Under the conditions of EBRT 90 s,mass concentration of inlet dimethyl sulfide 150 mg/m3,spray density 0.65 m3/（m2·h）and nutrient solution pH 6.8,the removal rate of dimethyl sulphide was 90%;When the volume loading was higher than 15 g/（m3·h）,the performance of the biotrickling filter was inhibited;When EBRTs was 90 s and 60 s,the optimum spray density was in the range of 0.56-0.65 m3/（m2·h）and 0.65-0.75 m3/（m2·h）,respectively;The dimethyl sulphide biodegrading microorgansims were sensitive to the change of pH,and the optimum nutrient solution pH was 6-7. |
