摘要

为研究甘蔗渣在处理印染废水脱色中的实际效果，以亚甲基蓝模拟废水为研究对象，考察了甘蔗渣在不同的实验条件下如吸附剂投加量、pH、振荡时间、初始质量浓度、温度等，对亚甲基蓝的吸附效果和规律.结果显示：在温度为30 ℃，pH为6～7，震荡时间为15 min的条件下，3 g甘蔗渣可使100 mL质量浓度为100 mg/L的亚甲基蓝的去除率达95%以上，30 ℃下甘蔗渣理论饱和吸附量为12.71 mg/g.甘蔗渣对亚甲基蓝的吸附过程可以用Langmuir、Freundlich、Temkin 等温吸附方程和二级吸附速率方程进行很好的描述，主要表现为物理吸附.

Abstract

In order to explore the effects of bagasse on the absorption of dye waste water

simulated wastewater of methylene blue used as the main pollution composition

it investigated the absorption effects of the bagasse on the methylene blue in aqueous solution under different conditions

such as different bagasse dosage

shaking time

initial concentration of methylene blue and temperature.The results indicate that the absorption rate of methylene blue is up to 95% in solution with initial methylene blue concentration of 100 mg/L

bagasse dosage of 3 g/100 mL

pH of 6～7

shaking time of 15 minutes and temperature of 30 ℃. The theoretical saturated absorption amount of bagasse is 12.71 mg/g at 30 ℃. Langmuir

Freundlich

Temkin models and secondary absorption rate equation can be used to suitably describe the absorption process of bagasse to methylene blue in aqueous solution

and the main absorption pattern is physical absorption.
