| Abstract: |
| A Double-membrane method based on Ultra Filtration (UF) and Reverse Osmosis (RO) was applied to save water in one PCB enterprise. The concentrated water in RO with COD of 200 mg/L above was sent to wastewater treatment station. In this paper, a three-dimensional electrode electrochemical oxidation reactor was adopted to reduce COD to level of direct discharge. The results show that COD removal rate is 60% above and power consumption of per kilogram COD is about 85 kWh. |
