摘　　要：该文在大量试验的基础上,就水力负荷对填料表面生物膜挂膜的影响做出了较为详细的试验得出的氨氮的稳定去除率大于60%为挂膜成功的标志时的临界水力负荷为5m3/m2.h。On the base of experiments, the hydraulic load effect on biofilm developing on the surface of media in biological contact oxidation（BCO）technology was given in this article. A conclusion was obtained that the critical hydraulic load for developing biofilm on surface of PS media may be 5m^3/m^2·h, if ammonia removal rate of 60% as the index of biofilin being developed.

关 键 词：水力负荷 生物接触氧化工艺挂膜 氨氮去除率
