| 摘 要： | 采用生活污水和A2N-SBR工艺对反硝化除磷过程进行了研究.在进水COD浓度为325mg/L,磷浓度为9.1mg/L,氨氮浓度为65mg/L的条件下,出水氨氮浓度和磷浓度分别为3.3mg/L和0.17mg/L,氮和磷的去除率分别为95%和98%.进水C/N比对A2N-SBR反硝化除磷体系的除磷和脱氮效率都有重要影响,在进水C/N比为5时获得了最佳的脱氮和除磷效率;当C/N比小于5时,氮和磷的去除率都有大幅度的下降;当C/N比大于5时,氮的去除率未受到影响,而磷的去除率却有所下降.

| Abstract: | Experiments were conducted by using A2N-SBR process to treat the domestic wastewater.When the concentration of COD,phosphorus and ammonia of influent was 325 mg/L,9.1 mg/L and 65 mg/L respectively,the concentration of ammonia and phosphorus was 3.3 mg/L and 0.17 mg/L.The efficiency of nitrogen and phosphorus removal was 95% and 98%.The C/N of influent had important influence on the nitrogen and phosphorus removal of A2N-SBR process.The best efficiency of nitrogen and phosphorus removal could be attained at the C/N of influent was 5.When C/N was lower 5,the efficiency of nitrogen and phosphorus removal was all decreased.When C/N was higher 5,the efficiency of nitrogen removal was not influenced but the efficiency of phosphorus removal was decreased. |
