摘要
随着近几年地下式污水厂建设的增多,不同形式及类型的矩形二沉池得到了广泛应用。目前常用的矩形二沉池类型有双层平流式沉淀池、周进周出沉淀池和单层平流式沉淀池。结合相关文献、设计规范及多个实际工程案例,总结了矩形二沉池选择的设计选型原则,可供类似污水处理厂设计参考。
With the increasing construction of underground wastewater treatment plants in recent years,different forms and types of rectangular secondary sedimentation tanks have been widely used.At present,the commonly used types of rectangular secondary sedimentation tank are double-deck horizontal sedimentation tank,sedimentation tank with peripheral feed and peripheral outflow and single-deck horizontal sedimentation tank.Combined with references,design specifications and a number of practical engineering cases,the design and selection principles of rectangular secondary sedimentation tank are summarized,which can be used as a reference for the design of similar wastewater treatment plants.
