摘　　要：颗粒污泥相对于传统活性污泥,具有沉降性好、稳定性强和脱氮效率高等优点,备受研究者关注。传统自凝形成的颗粒污泥具有周期长、稳定性差和成本高昂等问题,限制了其在硝态氮废水处理领域的大规模应用。金属阳离子的加入会影响颗粒污泥的形成、加速污泥造粒及提高系统长期运行的稳定性。笔者通过查阅相关文献,总结了颗粒污泥形成的机理以及增强颗粒污泥结构的相关措施,旨在为硝态氮废水的达标排放提供技术指导。Compared with traditional activated sludge,granular sludge has a series of advantages,such as good settling,strong stability and high nitrogen removal efficiency,which give it a wide application prospect and attracted much attention from researchers.The pellet sludge formed by traditional self-coagulation has the problems such as long period,poor stability and high cost,which limits its large-scale application in the field of sewage treatment.The addition of metal cations affects the formation of granular sludge,accelerate sludge granulation,improve the stability of long-term operation of the system.By reviewing relevant literature,we summarized the formation mechanism of granular sludge and relevant measures to strengthen the structure of granular sludge,aiming to provide technical guidance for the standard discharge of nitrate wastewater.
