摘　　要：为了降低合成革废水的毒性,提高废水的可生化性,采用臭氧紫外催化氧化+化学沉淀组成预处理,后经生物法处理,取得了较好的处理效果。结果表明:化学需氧量(COD)、二甲基甲酰胺(DMF)和二甲胺(DMA)的平均去除率分别达到99%、96%%和96%左右。该工艺克服了传统生物处理中废水的可生化性差、无法提供足够的碳源供生物脱氮等问题,而且简单、经济,对于该废水治理具有推广应用价值。This study was undertaken with the aim of reduce the toxicity of synthetic leather wastewater, improve the biodegradability of wastewater. We applied UV/O3 and chemical precipitation as pretreatment and later bio- logical treatment. The results showed that the chemical oxygen demand （ COD）, dimethylformamide （DMF） and dimethylacetamid （DMA） average removal rate is 99%, 96% and 96%. This process overcome wastewater low biodegradability, lack of carbon sources for biological nitrogen removal and other issues of the traditional biological treatment. This method is simplicity and economical, has application value for the wastewater treatment.
