秸秆对有色废水的吸附实验

Straw Straw Used as Absorbing Agent in Colored Waste Water

该文以甘蔗渣和稻草粉为吸附剂，分别对染料配制的模拟废水进行吸附实验，结果表明：2种吸附剂均可以高效地吸附红、蓝和黑等3色染料，并且吸附时间短，吸附温度影响小，吸附剂用量低；pH在5～7范围内吸附率最高，pH低于5以后吸附率显著下降。实验结果可为纤维质类生物吸附材料在造纸有色废水吸附处理中的应用提供参考。

Bagasse and rice straw powder were studied as absorbing agent in colored waste water in the paper. The experimental results showed that both powder could absorb red, blue and black dyes efficiently and fast at low dosage. Both of them had little temperature influence, pH was an important factor for absorbing effect, and the best pH range were 5-7. The results provided an example for bio-absorbing agent in paper making colored waste water treatment.
