范文编号:QH021  范文字数:15939,页数:37

 摘 要：
 目前，以废纸为原料进行瓦楞原纸的生产已经普遍受到许多造纸企业的欢迎，但造纸工业废水是水环境的主要污染源，而且废水不经过处理直接排放是造成水质污染的主要根源。因此，许多有效的处理技术应用于废水处理。经过对蔡伦纸业有限公司的废水处理系统的调研，熟悉了相关生产工艺和了解废纸废水的基本特性。又通过相应的实验对废水色度、固含量和化学耗氧量等进行分析，达到监测目的。对于废水监测中存在的问题提出相应的解决对策。
 本范文针对杭州市蔡伦纸业的综合废水进行了分时段监测，并对企业的废水处理现状做了认真的分析，同时在实验室研究的基础上，对该废水进行了混凝处理。
 在本研究中，废水处理的主要内容是采用了高效絮凝处理法，又称混凝沉淀法。控制相同条件，在废水中加入不同的絮凝剂进行反应，得到最佳絮凝剂和最佳工艺条件下的实验效果，并利用最佳絮凝剂对废水进行处理，获得了比较满意的效果。

 关键词：瓦楞原纸 ；化学耗氧量；混凝沉淀法；絮凝剂
 

 Determination and processing of the integrated waste water from paperboard mill
 Abstract:
 The waste paper as raw material for the production of corrugated base paper has generally been welcomed by many paper-making enterprises. But the paper industry wastewater is a major source of pollution of water environment. What's more, waste water without treatment   is the main root cause of water pollution. Therefore, many effective treatment technologies are applied in the waste water. After conducting a survey about the waste water treatment system from the Cai Lun paperboard mill, we are familiar with the company's related production technology and understand the basic characteristics of waste water from waste paper. Doing relevant experiments that we analysis on water color, solid content and chemical oxygen demand can achieve the purpose of determination. According to certain problems, there exist corresponding solutions in the monitoring of waste water.
 In this thesis, the determination of process of the integrated waste water from Cai Lun paperboard mill in Hangzhou is discussed on detailed.
 In the study, the high efficient flocculation technology is applied in the treatment of wastewater as the main content we deal with in this paper which is known as coagulation-sedimentation method. Under the same conditions, adding the response of different flocculants to the waste water. After the process of which, the best flocculants and optimum conditions of experimental results come out. And take advantage of the best flocculants for waste water treatment, to obtain satisfactory results.

Keywords：Corrugating; chemical oxygen demand; coagulation-sedimentation method; flocculants
