污泥沉降比(SV)是指将混匀的曝气池活性污泥混合液迅速倒进100ml量筒中至满刻度,静置沉淀30分钟后,则沉淀污泥与所取混合液之体积比为污泥沉降比(%),又称污泥沉降体积(SV30)以mL/L表示。该指标反应曝气池运行过程的污泥量,可控制、调节活性污泥的排放量,它还是污泥膨胀等异常现象的直观反应。
沉降性能及其评价指标 (1)污泥沉降比(Settling Velocity):SV% 又称30min沉降率,混合液在100ml量筒内静置30min后所 形成沉淀污泥的容积占原混合液容积的百分比,以% 表示。

污泥沉降比是污水处理过程中的主要分析项目之一,传统污泥沉降比的测量是人工操作,误差较大。
Sludge settlement ratio is one of the main analysis items. The traditional detection of sludge settlement ratio is operated manually, which may make too much deviation.
当回流比、 溢流率和絮体沉降特性处于变化中时,可用“状态点”的概念对活性污泥— 沉淀系统进行设计工作和系统分析。
The state point analysis can be used in the design and operation analysis of the activated sludge system as the RAS ratio, overflow rate and settling characteristics of flocci are varying.
对生物活性污泥的絮凝脱水性能的研究结果表明,LSDC在提高沉降速度、降低污泥含水率和污泥过滤比阻方面有明显效果,优于对比样CPAM。
It could be concluded that LSDC can obviously speed up the sedimentation rate of sludge, decrease moisture content and specific filtration resistance of sludge, which was superior to CPAM.
