| Abstract: | Combined process is one of the development directions to treat PCB wastewater. The optimal technological conditions of acidification, Fenton oxidation and coagulation processes have been ascertained by single factor experiments separately. According to the optimal conditions, the development wastewater from PCB production is treated by the combined process. The conclusion shows that the total COD removal rate of acidification-Fenton -coagulation is up to 94%, treatment effect is good, and the effluent COD is only 46 mg/L, better than the acidification-coagulation-Fenton oxidation process. The turbidity is reduced from 619 NTU to 3 NTU, and removal rate is about 99.5%. The experiments provide reference for the application of the process. |
