生物慢滤工艺对COD、 SCOD和浊度去除率分别可达到49％、46％和77％；对COD、 SCOD和浊度，系统表层填料对COD、 SCOD和浊度的去除贡献较大；在填料5 cm以下装置对有机物和浊度的去除曲线斜率基本一致。生物慢滤池对于TP和溶解性磷酸盐可达到70％以上；系统对总氮去除率一般只有18．0％～30．0％，对氨氮去除率可达33％～67％。沿不同深度，磷和总氮的去除率基本呈不断增大的趋势；而氨氮的去除率呈现先增大后减小的规律。

The removal efficiencies of COD, SCOD and turbidity can reach 49%, 46%and 77%, respectively.The surface layer had larger contribution than the lower layers for COD, SCOD and turbidity removal.The curve slopes had no conspicuous variation for organic and turbidity removals behind 5 cm filler.The removal efficiencies of TP and dissolved phosphate can reach 70%.In addition, the removal rate of TN was only 18.0%~30.0%, however, the removal rate of ammonia nitrogen can reach 33%~67%.The TP and dissolved phosphate removal efficiencies had the increasing trend along the different depth, but for ammonia nitrogen removal, it was decreased first then increased.
