改性膨润土对造纸废水的吸附作用

The Adsorption of the Modifiable Bentonite for Paper Making Wastewater

采用多种实验方法、对膨润土的改性进行研究，并对改性膨润土用干造纸废水处理，进行了条件实验．实验结果表明：经改性制得的ＭＭＨ－膨润土对造纸废水的ＣＯＤ去除率有明显提高．

The modification of the bentonite were studied by various experimental methods. The conditional tests for treating the paper making wastewater by the modifiable bentonite are carried out.The experimental results show that the removal rate of COD of the paper making wastewater has been improved obviously after bentonite was modified.
