Treatment of High Concentration Wastewater Containing Phenols and Aldehyde from a Small Phenolic Resin Plant

Abstract:

Wastewater from Phenolic resin production contains high concentration of phenol and formaldehyde. A combining process consisting of secondary condensation, fenton oxidation, coal fly ash adsorption and sand filter was adopted in the treatment of wastewater from phenolic resin factories. The feasibility of the process was already demonstrated by its practical operation results. After treatment by this method, not only did the effulent water reach the first order of Integrated Wastewater Discharge Standard (GB 8978-1996) and a certain amount of phenolic resin was also satisfactorily recovered.
