摘要
针对家具制造企业涂装过程产生的低浓度、大风量含挥发性有机物(VOCs)废气,提出了基于生物法处理该类废气.本方法通过在生物滴滤反应器中接种已培育的不动杆菌属(Acinetobacter sp.),重点解决现有涂装废气中主要成分--二甲苯3种同分异构体的降解效率问题,同时降低当前涂装废气治理技术存在的运行费用高等弊端.试验研发出1套设计气量为120 m^3/h的生物滴滤塔净化装置,并对本装置降解二甲苯的效果及其工艺参数优化进行了研究.结果表明,进口质量浓度为600 mg/m^3时,该装置处理二甲苯3种同分异构体的降解效率可分别达到92.54%,94.18%和90.53%. 3种同分异构体的降解效果从好到差依次为:间二甲苯,对二甲苯,邻二甲苯.因此,该装置可作为解决家具制造行业涂装废气污染问题的新途径.
For low-concentration, high-volume air emissions containing volatile organic compounds(VOCs) generated during the painting process of furniture manufacturing companies, this type of waste gas is treated based on biological methods. In this method, the inoculated Acinetobacter sp. were inoculated in the bio-trickling filter reactor, and the main components in the existing coating exhaust gas, xylene, were mainly addressed. The problem of degradation efficiency of isomers, while reducing the operating costs of the current coating exhaust gas treatment technology and other disadvantages. The experiment developed a set of biotrickling filter purification equipment with a designed gas volume of 120 m^3/h, and studied the effect of the degradation of xylene by this device and the optimization of its process parameters. The results show that when the inlet concentration is 600 mg/m^3, the degradation efficiency of the three isomers of xylene treated by the device reaches 92.54%, 94.18% and 90.53%, respectively. The degradation effects of the three isomers are m-xylene>p-xylene>o-xylene. Therefore, the device can be used as a new way to solve the problem of paint pollution in the furniture manufacturing industry.
