| 摘 要： | 在常规水处理工艺前增加生物预处理工艺,研究接触氧化沟和BAF分别作为混凝沉淀工艺的预处理工艺对石油类污染物的去除效果。原水石油类含量平均值为0.19mg/L,在三氯化铁投加量80mg/L时,接触氧化沟+常规混凝沉淀出水石油类含量平均值为0.07mg/L;BAF+常规混凝沉淀出水石油类含量平均值为0.039mg/L。结果表明,BAF作为给水生物预处理工艺对石油类污染物的去除能力优于接触氧化沟工艺,实验期间其后续混凝沉淀出水达标率为86.7%。

| Abstract: | Adding biological pretreatment unit,oxidation ditch or biological aerated filter at conventional water treatment process,and the removal efficiency of petrochemical pollutants with the process was separately studied.Average petroleum content in raw water was 0.19mg/L,and was reduced to 0.07mg/L by oxidation ditch and conventional coagulation and sedimentation process,in which the dose of PFC was 80mg/L.Under the same condition,effluent of biological aerated filter(BAF)and conventional process averaged to 0.... |
