摘　　要：本试验对新开发的悬浮载体生物膜反应器进行了不同进水水质处理实验研究。考察了不同碳氮比进水对反应器的CODCr和氨氮处理效果的影响。进水碳氮比在5～15范围内变化时，COD去除率呈先上升后下降的趋势；进水碳氮比为10左右时，悬浮载体生物膜反应器COD去除率均最大；在进水碳氮比为5左右时，恳浮载体生物膜反应器氨氮去除率均出现最高峰。同时从生物活性的角度初步探讨了结果产生的原因.The purpose of this paper is to study effect of ratio of carbon to nitrogen on performance of new renovated suspended carrier biofilm reaetor. In this paper the operational experiments under different ratio of carbon to nitrogen ranging from 5 to 15 are eondueted for treatment of COD and ammonia nitrogen,when the ratio of earbon to nitrogen is 10, the earbon oxidation in the new suspended earrier biofilm reaetor is most effieient, when the ratio of earbon to nitrogen is 5, the ammonia nitrogen removal ratio reaehes maximum. And the discussion is made on the behaviour of the microorganisms.
