北方地区A/O法与SBR法冬季运行特性分析

通过对生化法（SBR、A/O）处理低温生活污水的研究,结果表明：在常温条件下培养的污泥随着水温的降低,微生物的种属经过自然的筛选和淘汰,能够逐步适应低温的自然环境,A/O处理低温污水的效果可接近正常温度的水平,SBR低温运行由于泥水分离效果变差导致有机物去除率有所降低。

Analysis on the Operation of A/O Method and SBR Method in the North of China in Winter

The study of the treatment of domestic sewage at low temperature with biochemical method（SBR,A/O） shows that with the lowering of the water temperature,the sludge cultured at normal temperature may gradually adapt to the natural environment of low temperature after the natural selection of microbial species,the treatment effect of low-temperature sewage with A/O is close to that at normal temperature,the removal of organic matters decreases because of the variation of the separation efficiency of mud from water when SBR is applied at low temperature.
