Abstract:

The adsorption performance of different resins for the phenols and the regeneration performance of the resin are investigated based on the phenol-containing wastewater produced in needle coke production.The results show that the styrene-based macroporous resin has the best adsorption performance for the phenolic compounds in the waste water.Moreover,it can effectively remove the aniline in the waste water,i.e..850 mL waste water can be treated by 60 mL resin and the treated water can conform to effluent discharge standard.The resin after 3 times of adsorption-desorption experiments,still remains effective,which can be repeatedly used in continuous operation.This treatment is proved simple in process,economic and efficient in operation and environment-friendly,showing a broad prospect in utilization.
