摘要
好氧颗粒污泥(Aerobic Granule Sludge,AGS)具有生物保有量高、致密程度强、沉降性能好等优点,但因其启动周期长、难以长期稳定等缺点,限制了该技术的广泛应用。本文概述了AGS的理化性质及形成假说,综述了有机负荷、反应器类型、接种污泥、水力剪切力等参数对AGS形成的影响,总结了AGS应用于实际污水处理的部分中试案例,对AGS技术的推广应用提出了建议及展望。
Aerobic granular sludge(AGS)technology is a promising wastewater treatment technology of interest to many researchers with the advantages of good settling properties,compact structure,and a rich variety of microbial communities.It has been widely used in the treatment of urban wastewater,landfill leachate,printing and dyeing wastewater,and other effluents.However,long start-up time of granulation and poor stability of granules limit the popularity and application of AGS.This study reviewed the state of research on the physicochemical properties,formation mechanism,major factors affecting granulation of AGS.The application status of AGS process treating real municipal wastewater was also included.Finally,we proposed suggestions and prospects for the promotion and application of AGS technology.
