【摘要】 人们已经认识到反硝化聚磷菌(DPB)也是一种很重要的除磷菌.为了有效地评价除磷脱氮工艺,有必要研究污泥中微生物的特性.笔者在试验中所用污泥混合液取自纪庄子污水处理厂,对反硝化除磷菌(DPB)厌氧释磷、好氧/缺氧吸磷行为进行了可行性研究,比较了好氧除磷污泥与缺氧除磷污泥中微生物的不同特性和不同除磷活性.更多还原

【Abstract】 People have known that the DPB is also an important phosphorus removal.It is necessary to study the characteristics of microorganisms in the sludge in order to efficiently evaluate the biological nutrient removal(BNR)process.The miscible liquids of sludge for the experiment are taken from Tianjin Jizhuangzi WWTP.The feasibility of DPB releasing phosphorus in anaerobic conditions and adsorbing phosphorus in aerobic/anoxic conditions is studied.The different characteristics and different phosphorus removal activity of microorganisms in the aerobic phosphorus removal sludge and anoxic phosphorus removal sludge are compared.更多还原
