摘要
采用升流式厌氧污泥床反应器(UASB)去除蛋氨酸合成时产生的恶臭有机硫废液的恶臭气味.试验结果显示,UASB可以有效地去除废水中的主要恶臭物质甲硫基丙醛.在进水中甲硫基丙醛浓度高达8000mg/L的情况下,经两级串联的UASB处理后,其去除率达100%,而且使废水的恶臭消失.
In this paper, upflow anaerobic sludge blanket (UASB) was used to remove malodor of wastewater containing high concentration organosulfur compounds in methionine chemosynthesis industry .The experimental results showed that UASB could effectively remove 3-(Methylthio) propionaldehyde which was main malodor component of wastewater. Even the concentration of 3-(Methylthio) propionaldehyde of influents reached 8000mg/L ,the removal rate of 3-(Methylthio) propionaldehyde was 100% after treated by two series of UASB, and the malodor of wastewater disappeared as well.
