摘要
采用光电催化氧化处理电渗析浓水,当CODCr、TOC和进水氨氮的平均浓度分别为228.4、92和2.91 mg/L时,出水平均浓度分别为47.6、20、0.51 mg/L,达到《污水综合排放标准》(GB 8978—1996)中的一级标准。COD去除率随电导率值的提高而提高。光电催化氧化处理电渗析浓水耗电3元/t。
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.
