| 摘要: |
| 为进一步提高佛山某污水厂(CASS工艺)出水水质使其达到中水回用标准,以该厂污水为对象进行中试规模研究,探讨回流比和回流方式对间歇式缺氧/好氧膜生物反应器（A/O-MBR）脱氮除磷的影响. 结果表明:回流方式和回流比对间歇式A/O-MBR去除CODCr和NH+4-N效果无显著性影响,出水CODCr和NH+4-N均达到《城镇污水处理厂污染物排放标准》 (GB18918—2002)一级A标准;回流比和回流方式对系统去除TN和TP的效果均有显著影响,连续回流且回流比较大(350 ％)时,系统对TN和TP的去除效果均较差;回流比为130 ％时,连续回流有利于系统对TN的去除,去除率可达（48.00±10.05）％,出水TN可达一级A标准;回流比为130 ％时,间歇回流更有利于系统对TP的去除,去除率可达（78.27±23.41）％,出水TP满足一级B标准． |

| Abstract: |
| To enhance the quality of wastewater treatment plant’s (CASS process) effluent in Foshan to satisfy the water reuse standards, the impact of reflux ratios and reflux modes on nitrogen and phosphorus removal performance of a pilot scale of intermittent A/O-MBR fed with municipal wastewater was studied in this paper. The results showed that the reflux ratios and reflux modes had no remarkable influence on removal of CODCr and NH+4-N, and the concentrations of CODCr and NH+4-N in the effluent both reached the primary standard A of (GB18918—2002). The reflux ratios and reflux modes had significant influence on removal of TN and TP. The removal efficiencies of TN and TP were poor with a continuous reflux and a larger reflux ratio (350 ％); When the reflux ratio was 130 ％, the continuous mode was propitious to TN removal, and the removal efficiency could reach (48.00±10.05) ％, what’s more, the concentration of TN in the effluent reached the primary standard A, while the intermittent mode was also propitious to TP removal, the removal efficiency could reach (78.27±23.41) ％, and the concentration of TP in the effluent reached the primary standard B. |
