摘要
在好氧条件下，向反应器添加悬浮填料进行同时硝化反硝化的试验研究，研究影响生物膜同时硝化反硝化脱氮性能的因素。结果表明，在填料填充率为30％～40％、溶解氧为2～3mg/L、停留时间为6～8h时，系统对污染物的去除效果较好。
The research is about the experiment of adding suspended carrier in reactor for simultaneous nitrification and denitrification under aemblc condition. It is conducted to study the factors affecting the performance of simultaneous nitrifica tion and denitrification with biofilm in nitrogen removal. The result indicates that the contaminant removal efficiency is better when the filling rate of carrier is 30% ～ 40%, DO is 2 ～3 mg/L and retention time is 6 ～ 8 h.
