| 摘 要： | 在常温下采用移动床生物膜反应器处理低C/N比废水.结果显示:在填料填充比为40%、进水氨氮质量浓度为25 mg/L条件下,出水氨氮质量浓度基本稳定在4 mg/L左右,氨氮去除率在80%以上,硝化效果突出;进水C/N不足1时,TN及COD去除率分别能达到55%、60%以上,说明移动床生物膜反应器用于处理极低C/N废水具有良好效果.

| Abstract: | The extremely low C/N wastewater is treated with moving bed biofilm reactor at the normal temperature.The results show that: With the 40% filling proportion of the packing and about 25 mg/L ammonia nitrogen of the influent,the ammonia nitrogen of the effluent water is stably 4 mg/L,and the removal efficiency of the ammonia nitrogen is above 80%,the nitrification effect is prominent;while the C/N of influent is below 1 the removal rate of TN and COD can reach over 55%,and 60% respectively.These facts show th... |
