制糖厂的蔗渣飞尘(bagasse fly ash)可以作为吸附剂经济有效地降低制浆造纸工业的废水色度,而且这项技术已经开始应用于生产实践。该文研究讨论了生产中各种操作变量对吸附效果的影响,包括接触时间、初始浓度、吸附剂用量以及吸附剂粒径大小。研究结果表明:在蔗渣飞尘吸附剂用量为2g/L、接触时间为60min时,该吸附材料表现出良好的吸附能力,并且符合朗格缪尔和弗伦德利希吸附模型。
Bagasse fly ash from sugar mills can be used as an adsorbent to cost-effectively reduce the wastewater color of the pulp and paper industry, and the technology is already being used in production practices. This paper discusses the effects of various operating variables on the adsorption performance, including contact time, initial concentration, adsorbent dosage, and sorbent particle size. The results show that the adsorbent exhibits good adsorption capacity when the amount of sorbent is 2g / L and the contact time is 60min, which accords with the Langmuir and Freundlich adsorption model.
