摘要
好氧颗粒污泥具有沉降性能高、剩余污泥量少等优点,成为工业废水处理的一种新方法,探讨其稳定运行条件及在实际工业废水中的处理效果,有助于推动其工艺的基础性研究及工业化应用。文章概述了好氧颗粒污泥的特性,阐述了有机负荷率、底物组成、水流剪切力、间歇性饱食—饥饿喂养方式、进水组成等运行条件对好氧颗粒稳定性的影响,分析了其稳定运行条件,介绍了其在纺织废水、橡胶废水、牲畜废水和垃圾渗滤液等废水处理中的应用效果,并对深入研究好氧颗粒污泥形成机理的方法进行了展望。
Aerobic granular sludge technology has become a new mothod in the field of sewage treatment due to its excellent sedimentation performance and low residual sludge volume.By studying its instability in long-term operation and the application in industrial wastewater management,it will be help promote the foundational research and industrial application.The article summarizes the AGS characteristics,and discusses the formation and stable operation of AGS by factors such as organic loading rate,substrate type,water flow shear stress,intermittent feast-famine and influent composition,analyze the stable operating conditions,and lists the AGS in practical application of industrial wastewater treatment,including the textile wastewater,the rubber wastewater,livestock wastewater and municipal landfill leachate.Moreover,this paper states the study prospect of AGS formation mechanism.
