  潜水搅拌机的选型是一项比较复杂的工作,选型的正确与否直接影响设备的正常使用,作为选型的原则就是要让搅拌机在适合的容积里发挥充分的搅拌功能,一般可用流速来确定。根据污水处理厂不同的工艺要求,搅拌机流速应保证在0.15~0.3m/s之间,如果低于0.15m/s的流速则达不到推流搅拌效果,超过0.3m/s的流速则会影响工艺效果且造成浪费。所以在选型前首先确定QJB搅拌机运用的场所,如:污水池、污泥池、生化池;其次是介质的参数,如:悬浮物含量、粘度、温度、PH值;还有水池的形状、水深等。

  QJB型潜水搅拌机主要应用在市政和工业污水处理过程中的混合、搅拌和环流,也可用于景观水环境的养护,通过叶轮旋转运动达到创建水流的作用,改善水体质量,增加水中含氧量,有效阻止悬浮物的沉积。工艺和工业流程需要保持固、液二相或固、液、气三相介质均匀混合反应的场所。有效的搅拌是在整体流动条件下获得的,水池中的介质整体都在发生运动,并且成为搅拌工艺的一部分。整体流速通常为0.15~0.35m/s,现在往往被用作搅拌程度的设计参数。由于无循环通道的水池也存在着如何正确定义和测量所需流速的问题,故只在学术上规定一个整体流速是不够的。直到今天,整体流速仍是污水处理中可行的对通用搅拌状态进行定量分析的方法,而以沉积量、活体积、污泥分布均匀度等参数来定量表示搅拌度的工作正在进行之中。
