内容简介：

摘要摘要完成絮凝过程的絮凝池(一般常称反应池)，在净水处理中占有重要的地位。天然水中的悬浮物质及肢体物质的粒径非常细小。为去除这些物质通常借助于混凝的手段，也就是说在原水中加入适当的混凝剂，经过充分混和，使胶体稳定性被坏(脱稳）并与混凝剂水介后的聚合物相吸附，使颗粒具有絮凝性能。而絮凝池的目的就是创造合适的水力条件使这种具有絮凝性能的颗粒在相互接触中聚集，以形成较大的絮凝体(絮粒)。因此，絮凝池设计是否确当，关系到絮凝的效果，而絮凝的效果又直接影响后续处理的沉淀效果。絮凝搅拌机是絮凝池机械搅拌的装置，它主要用于废水处理的搅拌过程。本设计提到了絮凝池的设计，搅拌机的设计以及其工艺流程。关键词：关键词： 絮凝池 混凝剂 沉淀效果 絮凝性能AbstractAccomplish flocculation process flocculation pool (call reaction in general often pool) , handle middle in clean water occupying important position. Natural water suspension matter and limb matter grain diameter are very trivial.Be to dislodge these matter being backed by the means drifting along curdling generally , that is ,add the appropriate coagulant , blend through sufficiently in raw water, let colloid stability be spoiled the polymer (coming off after steady) and being situated between with coagulant water looks at and appraises an adsorption , makes a pellet have the flocculation function. But, that flocculation pool purpose is to create appropriate waterpower condition makes this have flocculation function pellet assembling, to form bigger flocculation body (catkin granule) in contacting middle mutually. But therefore, flocculation pool designs thinking that indeed or not, effect being related to a flocculation, the flocculation effect has direct impact to follow-up treatment precipitayion effect. The flocculation mixer is flocculation pool mechanical rabble device , it is used for the waste water treatment mixing process mainly. Design the design having mentioned flocculation pool originally, the mixer design and whose process flow.Keywords:Keywords: Flocculation pool Coagulant Precipitayion effect Flocculation function宁夏大学 2007 届过程装备与控制工程专业毕业设计1目录目录1 1 前前 言言.11.1毕业设计课题的目的、意义、国内外现状.11.1.1 毕业设计课题的目的、意义.11.1.2 国内外污水处理的现状.11.2 搅拌机在污水处理中的作用.21.2.1 搅拌机的发展概述.21.2.2 反应搅拌机的工作原理.21.3 絮凝的工作原理.31.4 水处理中的搅拌设备.31.5 絮凝搅拌机的适应条件和构造.31.5.1 絮凝搅拌机的适应条件.31.5.2 絮凝搅拌机的构造.41.6 本课题的设计思路.52 2 絮凝池的设计絮凝池的设计.62.1 絮凝池的设计探讨.62.1.1 絮凝的相似关系.72.1.2 假设和设想.102.2 絮凝池的设计要求及结果.153 3 絮凝搅拌机的设计絮凝搅拌机的设计.163.1 设计原始数据.163.2 设计要点.163.3 设计计算数据.163.4 桨叶的设计.173.4.1 桨叶结构尺寸确定.173.4.2 搅拌器转速计算.173.4.3 搅拌功率计算.194 4 电动机及减速器的选型电动机及减速器的选型.214.1 减速器和电动机的选型条件.214.2 电动机与减速器的选择.214.4 搅拌轴的设计及其结果验证.234.5 轴与桨叶、联轴器的连接.244.5.1 连接形式.244.5.2 联轴器与轴的连接.244.6 轴承的选型及轴的最终确定.245 5 支撑装置设计支撑装置设计.255.1 搅拌机的支承部分.255.1.1 机座.255.1.2 轴承装置.265.2 水下支撑座的设计.
