| Abstract: | Effluent of electrodialysis concentrated wastewater was treated by photoelectrocatalytic oxidation in this paper. The results show when average CODCr,TOC and ammonia nitrogen of influent is 228. 4,92 and 2. 91 mg/L,the average CODCr,TOC and ammonia nitrogen of effluent is 47. 6,20 and 0. 51 mg/L,which meet the first grade standard of GB 8978-1996. COD removal rate increases with the increase of conductivity value. The consumption of photoelectrocatalytic oxidation for concentrated wastewater treatment is 3 yuan/t. |
