为了探究污泥造粒颗粒在曝气中培养过程中形态、粒径、含水率、污泥沉降比(SV)、污泥体积指数(SVI)、悬浮物固体含量(MLSS)的变化,以污水处理厂活性污泥为材料,进行人工造粒,对造粒颗粒进行好氧培养.结果表明:培养20 d,颗粒污泥粒径由450.21 μm增加到598.60 μm,MLSS由5373.01 mg/L上升到5576.02 mg/L,颗粒污泥的SV由24.31%下降到19.31%;SVI由45.23 mg/L下降到37.41 mg/L;含水率由96.10%下降到95.19%.说明污泥造粒颗粒在曝气中培养过程中稳定性增强.

In order to explore the change ofmorphology,particle size,water content,sludge settling ra-tio in aeration in(SV),sludge volume index(SVI),the solid content of suspended solids(MLSS) of the sludge granule in the aeration process,the activated sludge in the sewage treatment plant was used as ma-terial to carry out artificial granulation and aerobic culture for granulation particles.The results showed that:in 20 days of incubation,the size of sludge particle increased from 450.21 μm to 598.60 μm and MLSS from 5 373.01 mg/L to 5 576.02 mg/L,SV d...
