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。

Abstract
Accomplish 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:  Flocculation pool   Coagulant    Precipitayion effect   Flocculation function
