| 摘 要： | 根据船舶清洗废水水质变化大,成分复杂,生物毒性高的特点,提出了混凝-臭氧氧化-曝气生物滤池(BAF)的组合工艺.该组合工艺的关键是采用臭氧进行氧化处理,去除色度和部分有机物,并且提高废水的可生化性,再通过后续的BAF工艺去除大部分有机物.中试结果表明,在原水CODCr为2 000～3 500 mg/L的情况下,最终出水的CODCr低于300 mg/L,能有效处理此类有机物浓度高,水质变化复杂的洗舱废水.

| Abstract: | According to the characteristics of cabin-washing wastewater with rapid changed quality,complicated composition and high biological toxicity,a combination process of coagulation-ozone-biological aerated filter(BAF)was used.The key of the combination process was using O3 for oxidizing pretreatment,which reduced the color degree and part of organic matter,and increased the biodegrade ability of the wastewater at the same time.Finally,most of the organic matter was removed by the BAF.The result in the pilot pl... |
