  • 摘要: 研究了Fe/AC內电解-H2O2联合技术在降解浮选废水中浮选药剂苯胺黑药（DDA）的效果及可行性。通过正交和单因素实验，考察了其工艺条件参数对DDA和COD处理效果的影响。结果表明，在初始pH=3，Fe/AC质量比为2：1，H2O2投加量为0.6 mmol·L-1，Fe/AC IME和Fenton氧化工段HRT分别为60 min和20 min的条件下，模拟废水DDA和COD浓度由200 mg·L-1、395 mg·L-1分别降至28.7 mg·L-1和32.9 mg·L-1，去除率分别高达85.6%和91.7%。Fe/AC IME-H2O2连续处理实际浮选废水（COD 880~910 mg·L-1）96 h后，COD去除率仍维持在88.0%以上，残留浓度低于《污水综合排放标准》（GB 8978-1996）二级标准值。
    Abstract: The feasibility and efficiency of the Fe/AC internal micro-electrolysis/H2O2 (Fe/AC IME-H2O2) process for the degradation of dianiline dithiophosphoric acid (DDA) in flotation wastewater was investigated. With the aid of orthogonal and single factor experiments, the influence of process parameters on the removal of DDA and COD was discussed. Results indicate that the concentrations of DDA and COD in simulated wastewater decreased from 200 mg·L-1 and 395 mg·L-1 to 28.7 mg·L-1 and 32.9 mg·L-1, respectively. Furthermore, a removal efficiency of DDA and COD of 85.6 and 91.7%, respectively, was achieved with a pH of 3, Fe/AC mass ratio of 2:1, dosing quantity of 0.6 mmol·L-1 H2O2, and a hydraulic retention time (HRT) of the Fe/AC IME and Fenton-oxidation sections of 60 min and 20 min, respectively. The removal efficiency of COD in actual flotation wastewater with a COD of 880 to 910 mg·L-1 could reach as high as 88.0% after 96 h of continuous Fe/AC IME-H2O2 processing. The residual concentration of COD in the outlet wastewater satisfied the secondary standard of the Integrated Wastewater Discharge Standard of China (GB 8978-1996).
