摘要：无论在污水处理还是净水处理，使用沉淀池来分离固体和液体。虽然沉积池形式各不相同，但在水中去除颗粒物的基本的理论依据是一样的。平面沉淀池因其构造简单、方便管理、操作成本低、适应水质变化能力强，至今仍广泛应用于各种水处理工程和污水处理厂，同时又由于斜管沉淀池的处理效果较理想，占地面积较少，有着其自有的优势。本次毕业设计课题是净水厂固液分离结构的设计，主要包括絮凝池、斜管沉淀池设计原理的概述和有关的计算。79931

The design of the reservoir of the water purification plant

Abstract:In the process of water treatment，It is often used to separate the solid liquid from the sediment ，Although the sedimentation pond forms a variety of forms But the basic principle of removing particulate matter in water is the same 。 The flat flow sedimentation pool is simple to construct ，Convenient management，Low running cost ，To adapt to the strength of water quality ，It is still widely used in all kinds of water purification plants and sewage treatment plants。 At the same time, the processing effect of the inclined tube is ideal, Less area ，With its own advantages, So it is based on the requirement of water treatment to determine which precipitation pool is used。 This graduation design project is the design of the water purification plant, The calculation of the sedimentation ponds of the flat flow and the sedimentation of the inclined tube, and the calculation of the sedimentation ponds and the inclined tube sedimentation pools, This paper compares the requirements of the water treatment of the sedimentation tank and the settlement of the inclined tube ，Finally, the solution of the sedimentation pond is determined。

KeyWords:Water treatment works ; Tank process; Inclined tube sedimentation tank; Advection sedimentation tank
