1、本科毕业论文题目絮凝剂处理废水的研究进展学院城乡建设学院专业环境工程学生姓名学号年级指导教师职称I絮凝剂处理废水的研究进展I摘要:在污水处理领域中,絮凝沉淀法是应用最普遍且成本较低的处理工艺。絮凝剂是该工艺的核心部分,它不仅可以用来降低原水的色度、浊度等感观指标,去除多种有机物、重金属粒子和固体悬浮颗粒,也可以自成系统,独立进行水处理,还可以与其它处理方式进行组合进行水处理。因而絮凝剂在水处理方面有着工艺简单、操作简便、高效率、低成本以及绿色环保的特点,比其它水处理工艺更具优越性。本文讨论了絮凝剂的研究现状,分析了各种絮凝剂
2、的分子结构、理化性质、絮凝机理,对比了絮凝剂在处理造纸、印染和重金属废水的处理效果,分析了絮凝剂处理废水存在的问题,并提出相关措施,以为研制和开发高效、无公害和低成本的新型絮凝剂提供理论基础。关键字:絮凝剂;处理废水;效果;措施IVAdvancesinResearchonWastewaterTreatmentbyFlocculationAbstract:Inthewastewatertreatmentfield,flocculatingsedimentationisthemostcommon-usedandlow-costa
