摘要
研究表明 ,炼油厂外排污水采用悬浮载体生物接触氧化、砂滤和臭氧生物活性炭工艺深度处理 ,主要污染物都有良好的去除效果 ,总出水清澈、无色 ,可以满足多种回用要求 .分析表明 ,大部分还原性污染物通过生物深度处理而去除 ,而微量有机物主要由臭氧生物活性炭去除 .工艺系统具有除污染效率高、运行稳定。
It is showed according to the study that the process of suspended carrier biological contact oxidation (SCBCO), sand filtration, ozonation and biological active carbon (BAC) can be used to deep treat oil refinery wastewater effectively, pollutants are removed with high efficiencies. The effluent is limpid and colorless, can meet with many reuse field requirement. Through the analysis, most of the pollutants are removed by SCBCO, however, trace organic compounds are reduced at the stage of O 3+BAC treating. It is feasible to deep treat oil refining and petrochemical wastewater with this process.
