| 摘 要： | 反硝化菌和聚磷菌在同一系统中竞争少量可溶性有机物引起的矛盾一直是传统生物脱氮除磷工艺的焦点问题．在污水处理系统中碳源的缺乏会影响整个系统的脱氮除磷效果．分析了碳源缺乏的原因，提出了着重从两个方面解决碳源缺乏问题：一方面是在时间或空间上将脱氮除磷分开的工艺改进，另一方面是寻找快速可替代有机碳源，并对有代表性的Biowin工艺的运行情况作了分析．

| Abstract: | It is a focal problem in conventional biological nutrient removal that denitrifying bacteria compete with phosphate accumulating organisms(PAO) for limited dissolved organisms.In a sewage treatment system,the shortage of the element of carbon may lessen the effect of biological nutrient removal.Upon the basis of an analysis of the factors causing the insufficiency of carbon content,two modes of technological improvement are recommended to settle the problem of carbon sources:one is to separately arrange the processes of biological nutrient removal,the other,represented by Biowin method,which is discussed much here,is to seek available rapid substitute carbon sources. |
