Research on application of electrochemistry-biological contact oxidation in PCB wastewater disposal

This paper introduces a engineering application of electrochemistry-biological contact oxidation in PCB wastewater disposal. The running outcome of the project application indicates that the removal percentages of Cu²⁺ and CODcr reach 99% and 87% respectively. The operation of this project is ease in application, stability in running with constant up-to-par outcome.
