摘　　要：常规生物脱氮除磷工艺存在相互影响和制约的因素 ,因此脱氮和除磷效果难以同时达到最佳。根据研究提出了生物膜与活性污泥结合的新工艺 ,可同时高效地脱氮、除磷和去除有机物。试验结果表明 ,氨氮去除率达 99%以上 ,TN、TP和COD的去除率分别达到 85%、95%和95%Some factors that are mutually affected and restrained exist in traditional processes for biological removal of nitrogen and phosphorus from wastewater. Therefore, it is difficult to obtain the optimum results of nitrogen and phosphorus removal at the same time. A new biofilm-activated sludge process is described in this paper. The high efficiencies of nitrification, denitrification and phosphorus removal can be simultaneously obtained by the new process. The experimental results showed that the efficiency of ammonia-N removal is over 99%, and the removal efficiencies of TN , TP and COD are 85%、95% and 95% respectively.ResearchonNitrogenandP
