本研究旨在探讨电化学氧化与臭氧氧化耦合，以快速有效地去除工业废水中的高有机负荷。单独的臭氧化仅显示出将废水的COD降低约45%。使用掺硼金刚石电极的电化学氧化将COD降低99.9%，但每0.7L批次需要超过2h。当两种工艺耦合时，在约1小时内，COD去除率可达沿着99.9%，同时色度和浊度去除率最高。该耦合工艺几乎消除了COD，颜色和浊度，而无需添加化学试剂或改变pH值，并且不会产生任何污泥，因此它既有效又环保。
This work evaluates the coupling of electrochemical oxidation and ozonation to reduce the high organic load of industrial wastewater quickly and effectively. Ozonation alone is shown to only reduce the COD of wastewater by about 45%. Electrochemical oxidation using boron-doped diamond electrodes reduces the COD by 99.9%, but requires over 2h per 0.7L batch. However, when the two processes are coupled, the COD is reduced by 99.9% along with most color and turbidity in about an hour. The coupled process practically eliminates the COD, color, and turbidity without the addition of chemical reagents or changing the pH and doesn't generate any sludge, so it is both effective and environmentally friendly.
