摘　　要：采用静态吸附方法,考察了不同条件下矿化垃圾对亚甲基蓝溶液吸附处理效果的影响,并用Langmuir、Freundlich等温吸附方程进行了拟合。结果表明,矿化垃圾处理初始浓度为10 mg·L^(-1)亚甲基蓝溶液的最佳的矿化垃圾用量为25 g·L^(-1)、最佳pH为10,震荡最佳时间为7 h,脱色率达到98.83%;矿化垃圾对亚甲基蓝的吸附能用Langmuir、Freundlich等温吸附方程进行较好的拟合。The effects of absorption treatment of methylene blue solution by aged-refuse and isotherm models are studied by means of static absorption under different conditions. In the meantime, Langmuir and Freundlich isotherm equation are fit. The results show that when the initial concentration of treated methylene blue solution is 10 mg.L^-1, the best parameters are as follows：the amount of aged-refuse is 25 g. L^-1, the best pH is 10, the best time for the shock is 7h, decoloring rate is up to 98.83 %. The equilibrium data in aqueous solutions is well represented by the Langmuir and Freundlich isotherm models.
