| 摘 要： | 分别研究了无机碳源和有机碳源对厌氧氨氧化反应脱氮性能的影响。接种稳定运行的复合式UASB厌氧氨氧化反应器污泥至ASBR反应器进行批式试验,考察不同碳酸氢钠浓度及COD浓度条件下的氮素转化情况,研究碳源对厌氧氨氧化脱氮效果的影响。厌氧氨氧化反应适宜的进水碳酸氢钠浓度为1.5～2.0 mg/L,超过30 mg/L时有机碳源的存在对厌氧氨氧化反应产生抑制作用,COD浓度超过60 mg/L时反应器表现出反硝化特性。无机碳源对厌氧氨氧化反应的影响表现在提供充足碳源和调节反应器pH的综合作用,较高浓度的COD对厌氧氨氧化反应具有抑制作用。

| Abstract: | This paper aims to estimate the impact of inorganic and organic carbon source on the nitrogen removal effect of ANAMMOX reactor.Batch experiment was conducted in ASBR reactors and ANAMMOX sludge was inoculated from compound UASB ANAMMOX reactor.The nitrogen removal effect was observed at different sodium bicarbonate and COD concentration,and the impact was discussed.The experimental result showed that ANAMMOX reactor performed preferably with 1.5~2.0 mg/L sodium bicarbonate in raw water,and more than 30 mg/L COD would restrain the ANAMMOX activity,while denitrification reactor was observed with more than 60 mg/L COD.Conclusion was that inorganic carbon source impacted the ANAMMOX on two aspects of carbon source supply and pH regulation,and high COD concentration restrainsed the ANAMMOX activity. |
