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.
