摘要
为研究MBR工艺处理城市污水的脱氮除磷效果,本试验采用A2/O-MBR组合工艺,对混合型城市污水进行中试研究.结果表明,系统正常运行情况下,TN,TP,COD,NH3-N的平均去除率分别为74.59%,95.10%,93.04%,93.70%,平均出水浓度分别为9.51 mg·L-1,0.28 mg·L-1,28.24 mg·L-1,1.69 mg·L-1,试验期间,取得了较好的脱氮除磷效果.
In order to investigate the effect of the MBR process in phosphorus and nitrogen removal for munici-pal wastewater, A^2/O- MBR is used on the mixed municipal wastewater to do the pilot study in the test. The results show that, when the system is working under the normal condition, the average removal rates of TN, TP,COD,NHa-N are 74.59% ,95.10% ,93.04% ,93.70% , respectively, and the average concentrations of TN,TP,COD,NH3-N are 9.51 mg·L^-1 ,0.28 mg·L^-1 ,28.24 mg·L^-1, 1.69 mg·L^-1, respectively. which achieves good effect in phosphorus and nitrogen removal.
