摘要
根据絮凝动力学和生物吸附理论,提出了“絮凝吸附—沉淀—活化”的城市污水强化一级处理工艺,即活化污泥法。工艺对污染物去除的强化作用主要包括污泥的絮凝作用、吸附作用和生物代谢作用,而以前两者的作用为主。对城市生活污水的处理试验结果表明,该工艺能够较大程度地提高SS、COD、BOD、SCOD 等污染物的去除率,具有明显的强化一级处理效果。
Based on the theories of flocculation kinetic and biological adsorption,a new process for enhanced primary treatment of municipal wastewater,flocculation-adsorption-sedimentation-activation process named as“activcation sludge process”,was developed and reported in this paper.The enhancement action of the process for pollutant removal included flocculation,adsorption and biological metabolism.Among them,the first two were predominant.The results showed that the process could increase removal efficiencies of SS,COD,SCOD,BOD and other pollutants in wastewater obviously.
