 摘 要：
 目前，以廢紙為原料進(jìn)行瓦楞原紙的生產(chǎn)已經(jīng)普遍受到許多造紙企業(yè)的歡迎，但造紙工業(yè)廢水是水環(huán)境的主要污染源，而且廢水不經(jīng)過(guò)處理直接排放是造成水質(zhì)污染的主要根源。因此，許多有效的處理技術(shù)應(yīng)用于廢水處理。經(jīng)過(guò)對(duì)蔡倫紙業(yè)有限公司的廢水處理系統(tǒng)的調(diào)研，熟悉了相關(guān)生產(chǎn)工藝和了解廢紙廢水的基本特性。又通過(guò)相應(yīng)的實(shí)驗(yàn)對(duì)廢水色度、固含量和化學(xué)耗氧量等進(jìn)行分析，達(dá)到監(jiān)測(cè)目的。對(duì)于廢水監(jiān)測(cè)中存在的問(wèn)題提出相應(yīng)的解決對(duì)策。
 本論文針對(duì)杭州市蔡倫紙業(yè)的綜合廢水進(jìn)行了分時(shí)段監(jiān)測(cè)，并對(duì)企業(yè)的廢水處理現(xiàn)狀做了認(rèn)真的分析，同時(shí)在實(shí)驗(yàn)室研究的基礎(chǔ)上，對(duì)該廢水進(jìn)行了混凝處理。
 在本研究中，廢水處理的主要內(nèi)容是采用了高效絮凝處理法，又稱混凝沉淀法。控制相同條件，在廢水中加入不同的絮凝劑進(jìn)行反應(yīng)，得到最佳絮凝劑和最佳工藝條件下的實(shí)驗(yàn)效果，并利用最佳絮凝劑對(duì)廢水進(jìn)行處理，獲得了比較滿意的效果。

  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
