摘　　要：研究了基于生物填料的染料废水脱氮工艺,考察了温度、停留时间、碳源等因素对生物填料脱氮性能的影响。试验结果表明,在脱氮温度为35℃,添加醋酸500 mg/L作为反硝化细菌的营养物质条件下,停留时间可缩短至2 h,废水总氮质量浓度从80 mg/L降至30 mg/L左右,总氮去除率达到60%以上。The denitrification process of dye wastewater based on biological filler is studied.The effects of temperature,residence time,carbon source on the denitrification performance of biological fillers are studied.The results show that when the denitrification temperature is 35℃and 500 mg/L of acetic acid is added as a nutrient for denitrifying bacteria,the residence time can be shortened to 2 h,and the total nitrogen concentration of wastewater can be reduced from 80 mg/L to 30 mg/L,the removal rate of to⁃tal nitrogen reaches more than 60%.
