| 摘 要： | 针对DSD酸废水难降解,高氨氮,高色度以及含盐的特点,设计了微电解-吹脱-SBR工艺。试验结果表明,该工艺对DSD酸废水有较好的处理效果。当炭铁比1.6,采用曝气加搅拌方式微电解50min,在pH为11～12,气水体积比为4000条件下吹脱6h,在溶解氧浓度为3mg/L条件下,SBR法生化反应6h,最终该工艺对COD、NH4+-N、色度去除率分别约为86.5%,95.3%和97%。

| Abstract: | Production of DSD acid, a kind of dye intermediates generates effluent in the de-oxidation process, which is characterized with being refractory to bio-degradation. This paper introduces a series of bench-scale experiments including micro-electrolytic, air stripping and the activated sludge in SBR process. Removals of CODcr, ammonium and color are evaluated. |
