摘　　要：皂素生产废水具有色度高、COD值大、可生化性差、酸度大等特点,一般通过二次处理很难达到排放标准。以活性炭吸附脱色的方法对二次处理过的水进行深度处理,通过实验,研究了活性炭的最佳投加量,最适pH值,最佳反应时间三个参数。实验结果表明,当活性炭投加量为0.7g/100mL,pH为2.5,反应时间为20min时,脱色率可达97%,COD的去除率为39.8%。The saponin wastewater which is characterized by high color, low pH and high organic concentration can hardly be treated only through twice treatments. The paper proposes that twice treated water can be deeply processed by using activated carbon adsorption. The experimental result indicates that optimal treatment effect can be achieved when the quality of activated carbon is 0.7g/100ml ; the pH value 2.5 ; and the reaction time 20 minutes, with the decolorant efficiency reaching 97% and the removal rate of COD 39.8%.
