采用序批式生物反应器SBR系统，考察反应阶段的间歇曝气和连续曝气对模拟生活废水中氮和磷的去除效果。研究表明： IASBR和SBR对NH4＋－N的去除率分别为99?30％和98?73％；对PO3－4－P的去除率分别为97?02％和67?47％。间歇曝气SBR对氨氮和磷酸根的去除率比连续曝气SBR高，有利于实现强化生物脱磷过程。间歇曝气SBR出水中氮、磷和COD浓度均达到了我国城镇污水处理厂污染物排放标准（GB 18918—2002）一级标准。

Biological nitrogen and phosphorus removal was investigated by an intermittently aerated sequencing batch reactor IASBR and a sequencing batch reactor SBR . The removal efficiencies of ammonium?nitrogen NH4+?N were 99?30% and 98?73% respectively in IASBR and SBR in steady operation while phosphorus PO3-4 ?P removal efficiencies were 97?02% and 67?47% in IASBR and SBR respectively. The intermittent aeration pattern has better effect for biological phosphorus removal. Effluent NH4+?N PO3-4 ?P and COD concentrations in the IASBR meets ChinaⅠEmission Standards.
