| 摘 要： | 针对生活污水低碳氮比的水质特点,采用SBR反应器接种低温储存的强化生物除磷颗粒污泥,来启动除磷亚硝化颗粒工艺,通过控制曝气强度及污泥龄实现除磷亚硝化的稳定运行,为后置CANON或厌氧氨氧化工艺(ANAMMOX)提供进水.污泥龄为30 d的条件下实现了出水TP小于0. 5 mg·L~(-1),COD浓度小于50 mg·L~(-1),亚硝酸盐氮积累率达到了90%以上.实验还得出,过高的曝气强度使除磷亚硝化性能恶化,可采用降低曝气强度和减小污泥龄的方式来改善除磷性能.污泥龄为40 d可以实现生活污水除磷亚硝化中的亚硝化性能进一步恢复,最终实现出水磷浓度保持在0. 5 mg·L~(-1)以下,COD及TP去除率分别稳定在80%及95%,亚硝酸盐积累率保持在90%以上,SVI值从初始的63 m L·g~(-1)降低到35 m L·g~(-1),颗粒污泥沉降性能良好,颗粒粒径在整个运行过程中保持在1 000μm以上.
