| 中文摘要: |
| 采用厌氧-曝气生物滤池工艺处理工业水杨酸废水，研究了不同进水ρ[COD(NaAc)]/ρ[COD(SA)] 比值（表示乙酸钠与水杨酸COD浓度配比）对有机物去除和脱氮效果的影响。结果表明：当进水SA浓度低于187mg/L时，经AF工艺处理后，废水BOD5/COD由0.27增大至0.38，UV254/ORP由-7.68增大至-3.22，可生化性明显提高。最佳HRT为10h，当比值为300:300时， COD去除率最高（91.74%），SA去除率为91.4%；当比值为0:600时，COD去除率最低（42%），SA去除率为52.48%。进水碳源变化对NH4 -N去除影响较小，去除率可达99.83%。水杨酸功能菌依赖于非水杨酸功能菌分泌的代谢产物生存，失去非水杨酸功能菌分泌的代谢产物后，水杨酸功能菌的活性开始降低。 |
| 英文摘要: |
| An aerobic-biological aerated filter process was employed to treat industrial salicylic acid wastewater, and the impact of different influent ρ[COD(NaAc)]/ρ[COD(SA)] ( the COD concentration ratio of sodium acetate to salicylic acid) on removal of organic matters and nitrogen was investigated. The results showed that the biodegradation of salicylic acid wastewater could be improved significantly by AF process. BOD5/COD was increased from 0.27 to 0.38 and UV254/ORP was increased to -3.22 on -7.68 with the influent SA concentration lower than 187mg/L. The optimum HRT was 10h, COD removal rate was the highest (91.74%) and the removal rate of SA was 91.4% with the ratio of 300 to 300. However, COD removal rate was the lowest (42%) and the corresponding removal rate of SA was 52.48%. The changes of carbon source hardly affected NH4 -N removal and the rate was up to 99.83%. SA degradation microorganisms’ survival mainly depended on non-degradable ones’ metabolites. The microbial activity of SA degradation decreased when secreted metabolites were reduced. |
