摘要
好氧颗粒污泥较传统絮状活性污泥而言,拥有更加规则的形状表观,更为紧凑致密的结构,更好的沉降性能,较强的抗冲击能力,富含丰富的微生物量,同时具备多种微生物功能。得益于众多特点,其已成为近些年的研究热点。但目前在好氧颗粒污泥的培养和应用方面还存在一些问题,例如好氧颗粒污泥初期颗粒形成速度缓慢,培养的条件较为苛刻,好氧颗粒污泥的形成机制尚未有明确的定论,成熟期的好氧颗粒污泥的结构不够稳定容易发生颗粒解体等,这些现存的问题在很大程度上阻碍了好氧颗粒污泥在实际工程应用中的推广。文章主要从好氧颗粒污泥的形成机理和影响因素两方面进行阐述,并对好氧颗粒污泥技术今后的发展进行展望。
Compared with traditional flocculent activated sludge,aerobic granular sludge has more regular shape appearance,more compact and dense structure,better sedimentation performance,stronger impact resistance,rich in microbial biomass and multiple microbial functions.Thanks to many characteristics,it has become a research hotspot in recent years.But at the moment,to the cultivation of aerobic granular sludge and applications also exist some problems,such as good a granular sludge particles forming speed is slow,the early training conditions are harsh,the formation mechanism of aerobic granular sludge is not yet clear,the structure of mature aerobic granular sludge unstable particles are prone to collapse and so on,these problems seriously hinder the application of aerobic granular sludge in engineering practice.This paper mainly discusses the formation mechanism and influencing factors of aerobic granular sludge,and prospects the development prospect of aerobic granular sludge technology.
