| 摘 要： | 以污水处理厂二沉池的活性污泥为种泥,采用SBR反应器初步完成了反硝化聚磷菌(DPB)的培养与驯化.在第1阶段的30 d里,污泥进行了厌氧-好氧驯化,聚磷菌好氧吸磷最终可基本稳定在85%左右,然后转变驯化条件进行第2阶段的厌氧-缺氧驯化,60 d后磷的去除率稳定在70%左右.通过实验得出,硝酸盐的消耗量与磷的吸收量基本呈线性关系,认为系统基本完成了污泥的驯化.

| Abstract: | The enrichment and cultivation of denitrifying phosphorus removing bacteria(DPB) using activated sludge from a full scale wastewater treatment plant were studied in a set of sequencing batch reactor(SBR) system.Firstly,the sludge mixtures were operated under anaerobic-aerobic(A/O) condition.30 days later,the removal rate of TP was about 85%.Then,the activated sludge was cultivated under anaerobic-anoxic(A/A) condition.During the experiment period of more than 60 days,the removal rate of TP was 70%.In this research,the relationship between phosphorus removal and NO~-_3-N consumption was also discussed.The result showed that two-phase cultivation was feasible. |
