摘要： 应用高径比为3.67的SBR反应柱R1培养好氧颗粒污泥，结果表明，经90 d培养即可获得粒径主要分布在0.5~1.0 mm、形状规则、结构密实的好氧颗粒污泥。R1中颗粒污泥MLSS为5 500 mg/L，SVI₃₀为36 mL/g，好氧颗粒污泥沉降性能明显优于常规活性污泥。应用培养的好氧颗粒污泥处理实际集成电路工业综合废水，废水COD、氨氮、TP和TN去除率分别在85%、80%、60%和47%以上。通过污泥产率分析得出，好氧颗粒污泥比活性污泥污泥原位减量41.5%。

Abstract: The sequencing batch bioreactor(SBR)reaction column R1 with height-to-diameter ratio of 3.67 has been used for cultivating aerobic granular sludge(AGS). The results show that after cultivated for 90 days,the AGS which mainly distributes on 0.5-1.0 mm,and have regular shape and dense structure can be obtained. The R1 granular sludge MLSS is 5 500 mg/L and SVI₃₀ 36 mL/g,the sedimentation performance of AGS is obviously better than that of conventional activated sludge. Since the cultivated AGS has been applied to the treatment of real integrated circuit industrial comprehensive wastewater,the removing rates of wastewater COD,ammonia nitrogen,TP and TN are 85%,80%,60% and 47% above,respectively. Obtained by means of sludge yield analysis,41.5% of insitu AGS is reduced,in comparison with activated sludge.
