生物-微电解组合工艺处理染料废水研究

采用上流式污泥床过滤器（upflow blanket filter，UBF）＋曝气生物滤池（biological aerated filter，BAF）＋微电解的组合工艺，对盐度接近2％、色度和COD分别约为8000倍和600．5mg／L的染料废水进行处理。经过连续120d的稳定运行后，组合系统处理效果良好，脱色率和COD去除率分别达到99％和75％以上。UBF和微电解单元均可以大幅度提高废水的可生化性，有利于进一步的生物处理。UV—Vis扫描和GC—MS分析表明，该组合工艺能破坏染料的发色基团和共轭双键，并能高效降解原水中的酚类、氯代有机物和复杂的杂环类化合物。实验结果表明，UBF＋BAF＋微电解的组合工艺是处理染料废水的一种有效方法。     

A/O生物法处理石化废水的研究

为了处理水质组成复杂,毒性大、有机物浓度较高的石化废水,采用先厌氧后好氧（即A/O生物法）的处理方法。研究结果表明,石化废水经厌氧处理后,其好氧可生化性提高20％～40％;当厌氧反应器进水有机负荷为5.2kgCOD/m³·d,水力停留时间为24h时,BOD5去除率为85％,COD去除率为83％,油去除率为91.1％;当曝气池污泥负荷为0.45kgCOD/kgMLSS·d,水力停留时间为4h时,BOD₅去除率为94.1％,COD去除率为92.7％,油去除率为96.3％。系统COD总去除率为85％～96％,BOD₅总去除率为95％～99％。A/O生物法为石化废水处理提供了理论依据。
