摘要：
针对混合(C4～C6)二元酸废水特点,以CODCr、色度作为评价指标,采用生物流化床-Ag/TiO2光催化氧化组合处理技术对其进行处理,并对反应条件进行优化。结果表明,采用该组合处理技术可有效去除二元酸废水CODCr及色度。当生物流化床水力停留时间10h,出水采用Ag/TiO2光催化氧化处理技术,反应器内停留时间45min,CODCr去除率96.1%,色度去除率>97.4%,完全达到二级排放要求。

Abstract:
Based on the characteristics of (C4 ~ C6) mixed diacid wastewater, it is treated by the combination of biological and photocatalytical methods, and the treatment condition is optimized. The result shows that this combination processing technology can remove CODCr and chroma efficiently, especially for chroma. When the retention time at biological fluidized-bed is 10 h, then the effluent is faced to photocatalytic treatment for 45 min, the removal rate of CODCr and chroma reaches 96.1% and 97.4% respectively.
