摘　　要：为了考察生物法治理污水处理场恶臭气体的实验效果,本研究采用生物滴滤、生物过滤和生物洗涤3种方法对某中石化公司化纤污水处理场4个恶臭气体挥发严重的污水池(生活污水提升池、氧化池、事故池和调节池)进行恶臭治理。实验结果表明,待生物塔稳定运行后,改变处理气量由0.1 m^3·h-1增大到0.2 m^3·h-1,相应的停留时间(EBRT)由172 s缩短到86 s,生物滴滤塔对甲醇、乙醇、环己烷和间-二甲苯这4种污染物的去除效率分别提升至96.80%、100.00%、92.15%和99.68%。此外,3台生物塔对于外界气温变化的适应性良好,但生物滴滤塔的压降始终未检出。根据小试实验结果,该化纤污水处理场恶臭的有效治理可以选用生物滴滤技术。To investigate the feasibility of a biological method for elimination of odorous gas from wastewater treatment plants, a biotrickling filter （BTF）, biofilter, and bioscrubber were used to treat the odorous gas, which was collected from four tanks （sanitary sewage lifting tank, oxidation tank, accident tank, and adjusting tank） of a Sinopec chemical fiber wastewater treatment plant.The results show that when the treatment capacity increased from 0.1 m3·h-1 to 0.2 m3·h-1, the corresponding empty bed residence time （EBRT） was cut from 172 s to 86 s.The BTF＇s removal efficiencies of methyl alcohol, ethyl alcohol, cyclohexane, and m-xylene increased to 96.80%, 100.00%, 92.15%, and 99.68%, respectively.Furthermore, the three biological reactors showed good adaptability to air temperature changes, but the BTF＇s pressure drop remained undetected.Hence, the odorous gas from this chemical fiber wastewater treatment plant was efficiently eliminated by BTF technology.
