采用复合曝气生物滤池工艺(生物活性炭BAC+曝气生物滤池BAF)将常规生化过滤、活性炭吸附与生物膜氧化技术相结合,对微污染源水处理进行试验研究,以期为其工程应用提供理论依据。结果表明,在源水为Ⅳ类水的情况下,复合BAF反应器对水中COD_(Mn)和UV_(254)的平均去除率分别为25.8%和18.4%,对NH3-N及浊度的平均去除率分别为86.2%和53.6%。复合曝气生物滤池工艺作为微污染源水的预处理净水设施能有效改善饮用水处理水质。在进一步进行其他几项水质指标的试验研究以及优化运行参数后可应用于工程实践。
The combined biological aerated filter process (BAC plus aerated biological filter BAF) combines conventional biochemical filtration, activated carbon adsorption and biofilm oxidation technologies to conduct experimental studies on micro-polluted source water treatment in order to provide a theoretical basis for its engineering applications. in accordance with. The results showed that the average removal rates of COD Mn and UV 254 in the combined BAF reactor were 25.8% and 18.4%, respectively, when the source water was type IV water, and the average NH3-N and turbidity were calculated. The removal rates were 86.2% and 53.6%, respectively. The composite aeration biological filter process as a pre-treatment water purification facility for micro-polluted source water can effectively improve the quality of drinking water treatment. It can be applied to engineering practice after further carrying out experimental research on several water quality indicators and optimizing operating parameters.
