摘要: 通过正交实验对海泡石改性条件及在酱油废水处理中的应用进行了实验研究。结果表明,酸度是海泡石改性的主要影响因素,海泡石在酸度4%,温度120℃,时间 12 h下改性,对酱油废水的脱色效果较好;当酱油废水浓度为1.033 mg/L,改性海泡石投加量为3 g(液固比70∶1),pH 5,反应时间90 min,改性海泡石对废水COD和色度的去除率分别达到59.6%和76.4%。Abstract: The influence factors of sepiolite modification and application in sauce wastewater treatment by orthogonal test were studied. The results showed that acidity was the main factor of sepiolite modification, and the decoloration effects of sauce wastewater was efficiency at acidity of 4%, reaction temperature of 120℃, time of 12 h. When COD concentration was 1.033 mg/L, the dosage of modified sepiolite was 3 g(the liquidsolid ratio was 70∶1), the reaction time was 90 min, the pH value was 5, the removal rates of COD and color could reach 59.6% and 76.4%, respectively.
