  • 摘要: 采用光催化氧化联用技术对电镀有机废水进行深度处理工程化实验。探讨了UV、UV+H2O2、UV+H2O2+TiO2、UV+H2O2+FeSO4、UV+H2O2+FeSO4+TiO2、UV+O3+TiO2 和 UV+O3+TiO2+H2O2等体系对废水有机污染物去除率的影响。结果表明,相较于其他反应体系,UV+O3+TiO2+H2O2体系具有更好的氧化效果,经碳滤处理后去除率达到90%以上,最终出水水质满足GB18918-2002一级标准(A标准)的要求。实际运行项目偿还期5.33年,NPV>0,内部收益率大于基准值10%。研究表明,UV+O3+TiO2+H2O2体系能降低加药量,工作量及运行成本。可为电镀企业实际废水处理提供现实依据,为优化电镀废水的处理工艺提供参考。
    Abstract: Photocatalytic oxidation coupling techniques were used in engineering experimental study of electroplating organic effluent advanced treatment.The various effects of COD removal by different systems:UV,UV+H2O2,UV+H2O2+TiO2,UV+H2O2+FeSO4,UV+H2O2+FeSO4+TiO2,UV+O3+TiO2 and UV+O3+TiO2+H2O2 were discussed. It shows that the UV+O3+TiO2+H2O2 system has the best oxidation effect compared with other systems. With the eventual effluent filtered by activated carbon, the COD removal rate can reach as high as 90%, which meets the GB18918-2002 standard (A Level). Actual project repayment period was 4.31 years, NPV > 0, internal rate of return is greater than 10% benchmark. Experimental investigation shows that, the adoption of UV+O3+TiO2+H2O2 system can reduce the raw materials dosage, workload and running cost,which will provide realistic basis and reference to electroplating wastewater treatment process optimization.
