铁碳微电解—A/O组合工艺处理精细化工废水

Study on treatment of fine chemical wastewater by the combination of the ferric-carbon micro-electrolysis and the A/O process

嘉兴某精细化工厂采用铁碳微电解—A/O组合工艺处理生产废水。运行结果表明,出水水质稳定,COD去除率可达79.12%,出水可稳定达到《污水综合排放标准》(GB 8978—1996)三级排放标准,工艺处理成本为1.1元/m3。该工艺具有处理效果好、耐冲击负荷能力强、经济效益高等特点,在精细化工废水的处理中具有很好的应用价值。

The combination of the ferric used to treat the fine chemical wastewater in carbon micro-electrolysis and the A/O process was some fine chemical factory in Jiaxing. The operation results showed, the water quality in effluent from this combined process was stable; the COD removal rate could reach 79. 12%. the effluent could meet the third discharge grade of the Integrated wastewater discharge standard （GB 8978-1996）; the cost was 1.1 RBM/m^3. This process had the advantages of good treatment effects, strong resistance of impact load, high economic benefits and so on. There should be a wide application of this process in fine chemical industrial wastewater treatment.
