环境工程专业学生设计性实验报告实验课程名称混凝剂（硫酸铝）与污泥反应时间的不同对污泥比阻的影响＿指导教师＿董春欣＿＿＿＿＿＿孙镜伟＿学号＿＿12310113＿＿＿专业＿＿＿环境工程＿＿班级＿环工1201＿＿＿＿摘要:根据长期实验教学中所取得的经验,对污泥比阻实验中几个参数的确定和经常碰到的一些问题,提出了自己的看法和解决的办法,为比阻实验的可操作性提供了帮助。

混凝剂种类繁多，如何根据水处理厂工艺条件、原水水质情况和处理后水质目标选用合适的混凝药剂，是十分重要的污泥比阻作为反映污泥脱水性能的主要参数,是水厂生产废水调质及脱水工艺的重要控制指标.指出了常规污泥比阻抽滤测定方法中存在的测定指标多、操作复杂、测定历时长等问题.针对自来水厂生产废水的水质特点,根据污泥比阻的测定理论。
