【摘要】 采用一体式臭氧催化氧化-曝气生物滤池组合工艺深度处理纺织印染废水,处理水量为6×10~4m~3/d,经一体式工艺处理后主要出水水质指标达到《纺织染整工业水污染物排放标准》(GB 4287—2012)表3排放限值(COD≤60 mg/L,色度≤30倍)。与分离式臭氧催化氧化-曝气生物滤池工艺相比,该工艺具有占地面积小、运行费用和投资成本低的优点。更多还原

【Abstract】 The integrated catalytic ozonation and biological aerated filter process was used for dyeing wastewater advanced treatment with the capacity of 6 × 104 m3/d. The effluent could meet the direct discharge limits( table 3) of Discharge Standards of Water Pollutants for Dyeing and Finishing of Textile Industry( GB 4287-2012),which requires COD to be no more than 60 mg/L and chroma no more than 30 times. Compared with separated process of ozonation and biological aerated filter,the integrated process had the advantages such as less footprint,lower operation and capitalized cost.更多还原
