摘　　要：青霉素生产及产品提纯过程中产生的挥发性有机废气(VOCs)污染问题一直难以解决.采用生物滴滤塔对青霉素车间精馏残液中挥发出的含醋酸丁酯、正丁醇和苯乙酸等有机物的废气,进行了3个多月中试规模的连续处理.结果表明,在青霉素车间正常排放废气(控制生物滴滤塔的进气流量为7.5 m3/h),且醋酸丁酯的进气质量浓度Ci<2 000 mg/m3,正丁醇Ci<2 400 mg/m3,苯乙酸Ci<370 mg/m3时,其去除率分别>95%、92%和接近100%,此时废气总VOCs的Ci<6 800 mg/m3,其去除率>94%.在有人为添加污染物的高负荷状态下,醋酸丁酯、正丁醇和苯乙酸的去除率保持在90%以上的最大进气容积负荷分别为:373.4 g/m3.h、317.2 g/m3.h和209.5 g/m3.h.生物滴滤塔内微生物相丰富,有很强的耐冲击负荷能力,操作容易,长期运行稳定,易于实现工业化.It is difficult to solve the pollution of volatile organic compound （VOCs） from the production and purification of penicillin. In this study, biotrickling filter was used to treat waste gases （VOCs） which were made up of Butyl acetate, n - Butyl alcohol and Phenylacetic acid and were volatilized from the raffinate in the penicillin workshop. The field pilot experiment was carried out continuously for more than three months. The results showed that when waste gases were discharged normally and inlet flow was monitored to 7.5m^3/h, removal efficiency of Butyl acetate, n - Butyl alcohol and Phenylacetic acid were 95%, 92% and 100% in the case of their maximum inlet concentrations of 2000mg/m^3, 2400mg/m^3 and 370mg/m^3, respectively. And meanwhile, the concentration of VOCs was less than 6800 mg/m^3 and its removal efficiency was more than 94%. Furthermore, when pollution materials were appended factitiously in order to achieve higher loading, removal efficiency of Butyl acetate, n - Butyl alcohol and Phenylacetic acid were all more than 90% in the case of their maximum inlet loading of 373.4g/（ m^3 · h）, 317.2g/（ m^3 · h） and 209.5g/（ m^3·h） , respectively. The biotrickling filter had abundant microorganism colony and stronger ability to resist shock of high inlet loading. Therefore, the biotrickling filter could be operated easily and steadily for long-term. It was a potential technology for removing VOCs and easy to realize industrialization.
