摘　　要：采用渗流式生物床处理北方某受严重污染河水,结果表明,在HRT为 8h的运行条件下,系统稳定运行后对NH+4 -N的平均去除率为 94. 4%,对COD的平均去除率为 51. 3%,对浊度的平均去除率接近 100%。生物床沿程污染物变化表明,在HRT为 8h条件下系统的处理能力还有较大的提升空间。自然条件下系统可在 40d左右完成启动,并在填料上形成稳定的生物膜。Use of seepage biological bed (SBB) for treatment of heavily polluted river water in north of China demonstrated that at HRT of 8 h, the system operates steadily, and the removal rate of NH^+_4-N and COD is averaged at 94.4% and 51.3% respectively, and the average removal rate of turbidity approximates to 100%. The variation of pollutant along the length of SBB shows that the system is capable of treating more pollutants at HRT of 8 h. Under the natural condition, startup of the system can be achieved in about 40 d, and stable biofilm is formed on the carrier.
