摘要
现有临汾市污水处理厂设计规模为7万m3/d,采用氧化沟工艺,出水执行二级排放标准。在改扩建方案中,规模扩容至8万m3/d,生物处理部分采用改良A/A/O工艺,深度处理部分采用混合-沉淀-过滤工艺,并且使用高效沉淀池和活性砂滤池等节省占地的构筑物形式,此外在方案中充分考虑对现有设施进行合理有效及充分地利用。
The existing Linfen City sewage treatment plant has a designed capacity of 70,000 m3/d,using oxidation ditch process,whose effluent conforms the secondary emission standards. In the renovation and expansion program,its capacity is increased to 80,000 m3/d,a modified A/A/O process is used for biotreatment,and a mixed-sedimentation-filtration process is used for advanced treatment,High efficient sedimentation tanks and active sand filter are also used. In addition the reasonable and adequate use of existing facilities is taken into account in the program.
