| 摘要: |
| 为研究阿莫西林对制药园区污水厂脱氮除磷的影响,采用小试A2O工艺处理生活污水,分别在进水投加阿莫西林前后,考察A2O工艺对COD、氮、磷的去除效果．结果表明:随着生活污水受到2～5 mg·L-1阿莫西林冲击,有机物降解菌活性受到明显抑制,COD平均去除率从86.9％下降至79.5％;系统硝酸细菌未受到明显抑制而亚硝酸细菌受抑制,导致硝化活性下降,氨氮平均去除率从95.5％下降至85％;系统缺氧区反硝化速率及厌氧区释磷速率影响不大,对总氮及总磷的平均去除效率影响较小． |

| Abstract: |
| A laboratory-scale A2O process treating domestic wastewater was carried out to investigate the influence of amoxicillin on nitrogen and phosphorus removal in pharmaceutical park wastewater treatment plant. The removal efficiency of COD, nitrogen and phosphorus had been studied before and after adding amoxicillin to influent. The result revealed that the activity of organism degrading bacteria was significantly inhibited and the average removal efficiency of COD decreased from 86.9％ to 79.5％ by the impact of amoxicillin (2-5 mg·L-1). The activity of nitrate bacteria was not inhibited while nitrite bacteria was significantly inhibited that the nitrification activity had been declining. The average removal efficiency of ammonia decreased from 95.5％ to 85％. The anaerobic phosphorus release, the denitrification performance and the removal efficiency of total phosphorus and total nitrogen was slightly affected. |
