尽管近几十年来废水处理的发展主要集中在生物反应器上，但二沉池 (SST) 在实现日益严格的废水质量标准方面也发挥着重要作用。本报告整理了 SST 理论、设计、建模和操作方面取得的许多重大进展。早期的 SST 仅根据溢流率等经验水力标准进行设计，无法识别污泥浓度和沉降性。如今，不仅有大大改进的设计程序，还有用于模拟全尺寸海表温度中水和固体分布和流动的流体动力学模型。九章涵盖了广泛的主题，包括： 生物污泥的絮凝和沉降行为 SST 性能评估协议 不同设计程序的开发和评估，例如通量理论和 ATV 设计规则 一维、二维和三维建模的开发和应用 圆形、矩形和垂直 SST 的设计和操作的基于经验的方面。 2006年第6号科技报告转载
Although developments in wastewater treatment over recent decades have focused on the biological reactor, the secondary settling tank (SST) also plays a major role in achieving increasingly stringent effluent quality standards. This report collates many of the significant developments that have taken place in SST theory, design, modelling and operation. Earlier SSTs were designed only by empirical hydraulic criteria such as overflow rate, which do not recognize sludge concentration and settleability. Today, there are available not only much improved design procedures but also hydrodynamic models for simulating water and solids distribution and flows in full-scale SSTs. Nine chapters cover a wide range of subjects including: Flocculation and settling behaviour of biological sludges SST performance evaluation protocols Development and evaluation of the different design procedures such as the flux theory and the ATV design rules Developments in and application of one- two- and three-dimensional modelling Experience-based aspects of design and operation of circular, rectangular and vertical SSTs.
