以含高氨氮的上海淀浦河水为原水，对填充有YSI型填料的悬浮填料床进行挂膜中试的启动性能试验。结果表明，在试验的第33d，氨氮去除率达80％以上，亚硝酸盐浓度没有积累，化学需氧量（CODMn）的去除率达10％左右，表明对于氨氮的去除挂膜已经成功。%Abstract: To investigate the start-up biofilm culturing process of suspended packing reactors, a pilot plant experiment was carried out with the raw water from Dianpu River in Shanghai. The result indicated that the removal rate of NH3-N was over 80% on the 33% day of the experiment, that the removal rate of CODm was about 10%, and that the nitrite accumulation was not observed. The start-up biofilm culturing process of suspended packing reactors has been proven successful in removal of NH3-N.
