摘　　要：为解决腌制皮蛋工业废水的脱色问题,利用正交实验研究方法,对聚丙烯酰胺、聚合氯化铝、过氧化氢、硅藻土和活性炭的脱色效果进行研究,确定在室温PH=7的条件下,按0.9%比例加入碘值为950的粉末活性炭,对腌制皮蛋工业废水脱色60分钟,可使其色度由4800降为32,达到国家污染物一级排放标准要求,为皮蛋加工企业处理工业废水脱色问题提供解决方案。In order to solve the decolorization problem of the industrial wastewater from preserved preserved eggs,the orthogonal experiment method was used to study the decolorization effects of polyacrylamide,polyaluminum chloride,hydrogen peroxide,diatomaceous earth and activated carbon.It is determined that under the condition of room temperature PH=7,powder activated carbon with an iodine value of 950 is added at a ratio of 0.9%to decolorize the industrial wastewater from preserved preserved eggs for 60 minutes,and its color can be reduced from 4800 to 32.So as to meet the requirements of the national first-level pollutant discharge standard,and provide solutions for the decolorization of industrial wastewater treatment by preserved egg processing enterprises.
