摘要
采用臭氧预氧化-BAF工艺对某钞票纸厂废水进行深度处理。结果表明,臭氧预氧化处理能提高废水的可生化性,废水经臭氧预氧化-BAF工艺处理后(臭氧用量100 mg/L,臭氧与废水接触时间5 min,BAF水力停留时间2.0 h)出水CODCr浓度约40 mg/L,色度几乎完全去除,能够达到较高的废水排放标准或作为中水回收利用。
The combining processes of ozone pre-oxidation and biological aerated filter were applied in the advanced treatment of one paper mill＇s wastewater. The result showed that： biodegradability of the wastewater can be improved by ozone pre-oxidation. COD of the effluent is less than 40 mg/L, and color of the effluent is almost removed completely by the subsequent biological aerated filter treatment, which meets the requirement of recycling or the more strict discharge regulation.
