摘　　要：化学生物絮凝工艺是利用化学和生物的协同作用对污水进行强化一级处理的深度集成工艺。由于化学絮凝、沉淀和生物絮凝、吸附、降解的共同作用,化学生物絮凝工艺对污水的处理效果优于单独的化学絮凝效果。但一些研究表明,投加量小时,二者的协同性能比投加量大时较佳,表明二者的协同作用不是简单的数学叠加,在高投加量时,二者还存在一定的抑制作用。本文对化学生物絮凝工艺中的化学和生物的抑制作用进行了探讨。The chemical biological-flocculation process is a highly enhanced primary treatment process that integrating the chemical flocculation and biological flocculation. The treating efficiency of the chemical-biological process is higher than that of chemical enhanced primary treatment process alone due to the cooperation of chemical flocculation, precipitation, biological flocculation, adsorption and degradation. Some researches indicate that the integrating effect is more obvious when the dosage is lower as compared to the higher dosage, implying there is not a mathematical synthesis,but an inhibiting effect between chemical flocculation process and biological flocculation process , especially under higher dosage. This study has a further probation into the inhibiting effect on chemical-biological flocculation nrocess.
