摘要：
Rotating biological contactor (RBC) has good effect for treating wastewater, while it is rarely reported to be used for treating canteen wastewater in frigid area as in this paper. After having cultivated the biofilm, this article studied the purification effect on disposing of sewage from dinning hall by RBC and its affecting factors such as input organic loading, stages and temperature. The results indicated that even in low ambient temperature, the COD removal rate can achieve an average value of 70% and NH4-N elimination rate is over 80% in average which displayed better effects. Microscopic observations showed that there were plenty of and varies kinds of microorganisms displayed in order in bio-discs.
