好氧颗粒污泥的研究现状及应用前景

Literature review of aerobic granular sludge for wastewater treatment

简述了好氧颗粒污泥的国内外研究现状,介绍了好氧颗粒污泥的形成机制、特性及影响好氧颗粒污泥形成的关键因素,如微生物表面疏水性、水流剪切力、进水底物、有机负荷、DO、pH、沉降时间、进水中Ca2+的添加及温度等。并对好氧颗粒污泥的研究方向和应用前景进行了展望。

This paper presents a literature review of aerobic granular sludge （AGS） for wastewater treatment, focusing on the fundamentals of AGS formation, the physicochemical and biological characteristics of AGS, and the effects of hydrophobic surface of the sludge, hydraulic shearing, organic loading, feed composition （N/COD and Ca^2＋ supplement）, settling time and temperature on the AGS performance in several type of bioreactors （AAA, AUSB, MBR and SBR）. It also lists some common problems of applying AGS and the necessary research areas to address those issues with the aim to make the attractive AGS option a more practical alternative for biological treatment of select wastewaters.
