Svi30/svi5
Websvi30既是衡量污泥沉降性能的指标，也是衡量污泥吸附性能的一个指标。一般来说，svi30值越大，沉降性能越差，但吸附性能越好；反之svi30越小，沉降性能越好，而吸附性能越差。 http://eekw.rcees.ac.cn/article/doi/10.12030/j.cjee.202405080

WebTwo sequence batch reactors (SBRs) with airflow rates of 4 (R1) and 6 (R2) 1 min(-1), respectively, were used to develop aerobic granules. Granules were well developed with excellent settleability in terms of SVI30 (sludge volume index,) of about 50 ml g(-1) in both reactors at the beginning. Web1 dic 2024 · The wet biomass density, SVI30, and SVI30/SVI5 of the kenaf granules were 1035 g L⁻¹, 30.6 mL g⁻¹, and 1.0, respectively, which met the standards of aerobic granules.
WebSVI＝混合液30min沉降后污泥容积／污泥干重＝（SV％×100）／MLSS. SVI反映了污泥的松散程度和凝聚性能, SV%是污泥沉降比,指曝气池混合液在量筒中静止30min后,污泥所占体积与原混合液体积的比值.它是控制活性污泥法运行的重要指标. MLSS是混合液悬浮固体浓 … WebWhen the volume exchange ratio decreased from 90% to 50%, the SVI30/SVI5 of R1 and R3 remained above 0.85, and the SVI30/SVI5 of R2 decreased, which may be caused by slight sludge bulking because of high suspended particles in the influent. Sludge samples (S1, S2 and S3) collected from three main reactors were used for high throughput analysis.
Web1 set 2024 · Fig. 1 d shows that the SVI5 and SVI30 significantly reduced in the first 40 days, and kept stable in the following 60 days. The ratio of SVI30/SVI5 increased to higher than 0.93 after Day 30, which indicated a strong settleability of AGS in the system.
