摘　　要：以城市污水处理厂的消化污泥为原料,通过干化处理制备成生物吸附剂,对模拟亚甲基蓝废水进行吸附研究。结果表明:污泥对亚甲基蓝的吸附效果明显,去除率达到90%以上,吸附过程符合Langmuir方程;温度越高吸附效果越好,pH值越高吸附效果越好;盐的存在对吸附产生抑制作用。Absorption of Methylene Blue dyes in water by dried digestion sludge was studied, which was easily made from the material of digestion sludge of municipal waste water treatment plant. The results showed that sludge as absorbent may be used effectively in removal of Methylene Blue waste water, and the rate of removal is up to 90% ;the higher the temperature or the higher the pH, the better the effect of absorption;but the existence of salt will restrain the process of absorption.
