【摘要】 为了研究活性污泥培养及运行过程中微生物指示特性,依据微生物的生理特征,采用SBR工艺,以新鲜的生活污水作为营养液直接曝气,通过控制pH值、温度、溶解氧等条件逐步培养活性污泥,实验同时对微生物相的演变规律与污水处理效果之间的对应关系进行了分析研究,得出了活性污泥培养的不同阶段及运行异常时微生物相的特征.更多还原

【Abstract】 According to the physiological characteristic of microorganism,SBR process is used to gradually cultivate activated sludge by controlling pH、temperature、dissolved oxygen etc.with fresh domestic sewage directly aerated as nutrient liquid for studying indicative character of microorganism in the course of cultivating activated sludge and running.Meanwhile,corresponding relationship between evolution of microorganism and treatment effect is analyzed and studied. Characteristics of microorganism at different stages of cultivating activated sludge and in the abnormal running period are obtained.更多还原
