污废水处理中好氧颗粒污泥技术研究进展

Review of the Aerobic Granular Sludge Technology Applied in Sewage Treatment

综述了好氧颗粒污泥技术在污废水处理工程中的研究情况.好氧颗粒污泥在实验室的阶段的研究主要集中于在高浓度有机废水处理、有毒有机物降解及脱氮除磷方面的研究,研究成果较为突出,多侧重于用各种模拟废水研究好氧颗粒污泥的形成条件.在实际污废水处理工程中的应用主要集中于对生活污水和工业废水的处理研究,侧重于工程中的处理效果,缺少对形成机理和运行条件方面的研究.在阐述国内外已有研究成果基础上,从多方面展望好氧颗粒污泥的研究方向和应用前景.

This paper reviews the researches of the aerobic granular sludge technology in wastewater biological treatment. Lab studies of aerobic granular sludge focus on the mechanism of high concentration organic wastewater treatment and toxic compounds ＇ degradation and nitro- gen and phosphorus removal. Research emphasis is put on the formation conditions of aerobic granular sludge in simulated wastewater. Field studies focus on the treatment of household wastewater and industrial wastewater. The emphasis is on the treatment effect rather than the theoretical basis and operation environment. We give a review of the status quo of research findings at home and around the world and predict the future researches and applications of aer- obic granular sludge.
