乙二醛脱色用活性炭的重复利用

对乙二醛脱色用活性炭进行了再生和重复利用实验研究，结果表明，通过简单的方法难以使活性炭再生，但一次脱色后活性炭仍具有较好的吸附能力，可重复使用，可大幅减少活性炭的使用量和产品的带损量，同时减少了脱色后活性炭的处理量，由此每年能为企业创造经济效益100万元。

Reuse of Decolorizing Carbon and Recover of Product

Reuse and recycling of decolorizing carbon were studied. The results indicated that recycling of the activated carbon was difficult through normal methods,but the carbon could be reused. When the carbon was reused,the total amounts would be substantially reduced,and the product loss was also lowered. Thus more than 1million yuan was saved per year,and the pressure of environmental protection was also reduced.
