摘　　要：通过实验室小试,以人工模拟生活污水为研究对象,考察了基于反硝化除磷理论开发的双泥膜法SBR工艺的脱氮除磷效果。长期试验结果表明:双泥膜法SBR工艺能使硝化菌和除磷菌各自在最佳的环境中生长,解决了传统工艺中脱氮和除磷的矛盾,节省了碳源和能源,并取得了稳定高效的脱氮除磷效果。在进水C∶N∶P为25∶5∶1,换液比为75%的情况下,系统对COD,TP和NH4+-N的平均去除率分别为89.13%、96.12%和86.78%。The ability of biological nitrogen and phosphorus removal by using synthetic wastewater was in- vestigated in biomembrane two-sludge SBR system based on the theory of denitrifying phosphorus removal. Long- term experiments showed that biomembrane two-sludge SBR system could enable nitrobacteria and denitrifying phosphorus removing bacteria to obtain their own optimal conditions, thus solving the contradiction of nitrogen and phosphorus removal in conventional process. So the better nitrogen and phosphorus removal efficiency with less carbon source and power source was achieved. Under the condition of C： N： P being 25： 5：1 and ratio of water exchanging 75% , the removal rates of COD, TP and NH4 -N were 89.13% , 96.12% and 86.78% , respectively.
