摘要
针对氨基酸发酵厂废气产生量大、组成复杂且各工序气体分布不均、污染物特性各异等特点,对氨基酸发酵厂废气进行全过程处理。对发酵、脱色和提取、板框压滤和蛋白烘干废气,分别采用两相生物、酸碱喷淋、洗涤-生物和文丘里-碱洗电除雾-低温等离子组合工艺。重点介绍了各工序废气处理工艺选择和工程设计参数。工程运行结果表明,各工序废气处理系统处理后的废气污染物指标均能达到《大气污染物综合排放标准》(GB 16297-1996)中要求的排放标准。
In line with the characteristics of waste gas from amino acid fermentation plant,such as a large emission amount,complex composition,uneven gas distribution in each process and different pollutants characteristics,full process control technology is used to treat with the waste gas. The two-phase biology,acid-base spraying,washing-biology and venturi-alkali washing electrostatic fog removal-low temperature plasma technologies are respectively used to treat with the waste gas generated in the four different process units including fermentation,decolorization/extraction,plate-frame filter pressing and protein drying.Review is focused on the selection of treatment technology for the waste gas generated in each process unit and engineering design parameters of treatment technology.The engineering operation results show that the pollutant index in waste gas of each process unit after the treatment can meet the emission standard value in China’s Comprehensive Emission Standard of Atmospheric Pollutants( GB 16297-1996).
