除磷微生物特性的研究是探明生物除磷机理的前提．本文通过菌属鉴别试验，分析了除磷生物膜中微生物的特点和其在生物除磷过程中所起的作用，确定出淹没式生物膜法除磷工艺中的优势菌属为假单胞菌属，其次依顺序为气单胞菌属、芽孢杆菌属、微球菌属、硝化杆菌属．%A Study on the characteristics of microorganism for phosphorusremoval is the premise of ascertaining the mechanism of biological phosphorus removal. Through the bacterial species identification test, the article analyzes the microorganism characteristics in phosphorus removal biofilm and the function in biological phosphorus removal process.Moreover, it is certain that the dominant phosphorus removal bacterial species is Pseudomonas and then Aeromonas, Bacillus, Micrococcus, Nitrobacter in the submerged biofilm process.
