| Abstract: | A combined physicochemical water treatment process of"coagulation-demulsification and activated clay adsorption"is developed to degrade polyurethane PU process wastewater from an automobile air filter plant.This combined process degrades the wastewater COD from 9500 mg/L down to 200 mg/L,the removal rate accordingly reaches over 95%and the effluent can subsequently be discharged directly into the biological treatment tank in the factory.The operating cost of the integrated process is low. |
