摘　　要：本研究针对工业园区废水处理问题,采用序批式反应器(SBR)开展了好氧颗粒污泥(AGS)技术的性能研究,并探索了硅藻土投加对AGS颗粒化进程和污染物去除性能的优化作用。实验结果表明:在运行40 d后,硅藻土的添加促进了颗粒化进程,好氧颗粒污泥的平均粒径分别为193.541μm和230.421μm,两组反应器均实现了高效、稳定的污染物去除,化学需氧量(COD)、总氮(TN)、总磷(TP)去除率分别为95.95%、80.7%~82.5%、95.6%~95.8%,满足《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准。微生物群落分析显示,AGS系统中Bacteroidota和Gammaproteobacteria的显著富集促进了污染物去除,而硅藻土的投加进一步提升了颗粒化进程和抗污泥膨胀能力。本研究验证了好氧颗粒污泥技术在工业园区废水处理中的适用性,为实际工程应用提供了理论和数据支持。This study addresses the challenges of treating industrial park wastewater by employing sequencing batch reactors(SBR)to investigate the performance of aerobic granular sludge(AGS)technology and explores the optimization effect of diatomaceous earth addition on AGS granulation and pollutant removal.After 40 days of operation,the addition of diatomaceous earth significantly accelerated the granulation process,resulting in average particle sizes of 193.541μm and 230.421μm for the two reactors,respectively.Both reactors demonstrated high efficiency and stable pollutant removal,achieving chemical oxygen demand(COD),total nitrogen(TN),and total phosphorus(TP)removal rates of 95.95%,80.7%~82.5%,and 95.6%~95.8%,respectively,meeting the Class A discharge standard of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants(GB 18918-2002).Microbial community analysis revealed that the significant enrichment of Bacteroidota and Gammaproteobacteria in the AGS system facilitated pollutant removal,while the addition of diatomaceous earth further enhanced granulation and inhibited sludge bulking.This study validates the applicability of AGS technology for treating industrial park wastewater and provides theoretical and practical data support for its engineering application.
