Abstract: A wastewater treatment plant that employs an activated sludge process and a method of operating the same is described. Wastewater influent is provided to a bioreactor configured to perform activated sludge processing to develop mixed liquor suspended solids (MLSS). The MLSS is passed from the bioreactor to a hydrodynamic separator (HDS) system, where separation operations are performed on the MLSS. The separation operations generate a low concentration MLSS stream and a high concentration MLSS stream. The low concentration MLSS stream is passed from the hydrodynamic separator system via a first output to a clarifier, and the high concentration wastewater stream is passed via a second output back to the bioreactor. The clarifier performs clarification operations on the cleaned wastewater stream and then outputs an effluent flow.

Abstract translation: 描述了采用活性污泥法的废水处理装置及其操作方法。 废水流入物被提供给生物反应器，其被配置为进行活性污泥处理以开发混合液悬浮固体（MLSS）。 MLSS从生物反应器传递到水力分离器（HDS）系统，其中在MLSS上执行分离操作。 分离操作产生低浓度MLSS流和高浓度MLSS流。 低浓度MLSS流从流体动力分离器系统通过第一输出传递至澄清器，高浓度废水流经第二输出返回生物反应器。 澄清器对清洁的废水流进行澄清操作，然后输出流出物流。
