用于焦化废水处理的焦粉综合利用技术

Comprehensive Utilization of Coke Powder in Coking Wastewater Treatment

焦粉具有与活性炭相似的性质,可作为活性炭的替代材料应用于焦化废水处理。文章介绍了关于焦粉改性为焦粉活性炭以及直接作为吸附剂处理焦化废水的研究,总结了各研究焦粉投加量、焦粉粒径、吸附时间、废水pH值对焦化废水处理效果的影响,同时分析了该技术在工程应用中存在的问题。结果表明该技术有待优化,其巨大的潜力应引起更多的关注。

Coke powder can replace activated carbon as the adsorbent applied in coking wastewater treatment because of the similar properties. Study on modifying coke powder into activated coke and conducting coke powder as adsorbent directly was both introduced. Influence factors of treatment effect concerned by many studies like coke powder dose,coke powder’ s grain diameter,adsorption time and coking wastewater p H was evaluated. In addition,the problem of such application in practice was studied. It is indicated that more researches should be attracted on coke powder applied to coking wastewater treatment as its great potential.
