| 摘 要： | 葡萄酒废水的季节性波动常造成生化处理系统不稳定,使传统的生化处理工艺难以满足新的污水排放标准的要求。研究了臭氧预处理工艺对葡萄酒废水的处理效果及主要控制参数,结果表明,单独的臭氧预氧化对COD几乎无去除效果,但对色度的去除可达到90%;采用O3/H2O2组合工艺可使COD的去除率提高4倍。经臭氧预处理的出水再采用SBR进行好氧处理时,出水COD能降至80 mg/L以下,COD的降解速度及程度都高于未经臭氧处理的稀释原水。高效液相色谱(HPLC)分析显示,经臭氧处理后,除麦芽糖成分被完全去除外,其他各种成分的数量变化不大;GC/MS对废水中多酚类有机物的分析显示,臭氧预处理可将大量难降解的多酚类有机物分解,从而有助于后续生化处理的出水达到更高的污水排放标准。

| Abstract: | Seasonal fluctuation of winery wastewater (WW) discharge always makes WW treatment system unstable and traditional biological treatment process is difficult to meet the new standards.The effect of pretreatment of winery wastewater by ozone and the main control parameters were studied in the experiment.Results showed that the increase of COD removal efficiency by O3 could be neglected,while the color removal efficiency could reach up to 90%.The removal efficiency of COD increased 4 times when O3/H2O2 combination systems were used to treat WW.When the effluent from O3 pre-oxidation system was treated by SBR,the COD is bellow 80 mg/L and its degradation rate is much higher than diluted raw water.HPLC analysis reveals that the main components of WW changed little after O3 oxidation,but maltsugar was completely removed.GC/MS analysis indicates that most polyphenols organics were degraded by O3 oxidation,and this is helpful to meet the new wastewater discharge standards. |
