【正文】 西南科技大學(xué)本科畢業(yè)生論文 I 制漿造紙廢水處理站的設(shè)計(jì) 摘要： 造紙 廢水已成為 水體污染 重要 污染源。該類廢水有機(jī)物濃度高、懸浮物多，因此厭氧技術(shù)成為造紙廢水處理中不可缺少的關(guān)鍵技術(shù)。 結(jié)合造紙廢 水的水質(zhì)特點(diǎn)及傳統(tǒng)廢水處理工藝，本設(shè)計(jì) 把成熟處理方法和先進(jìn)技術(shù)以及節(jié)能裝置相結(jié)合， 選用 UASB+SBR 的聯(lián)合處理工藝 ， 污水經(jīng)過纖維回收機(jī)，再進(jìn)入調(diào)節(jié)池調(diào)節(jié)水量及 pH，再由 UASB 進(jìn)行厭氧處理，后進(jìn)入 SBR 池進(jìn)行好氧處理，通過處理，該廢水可達(dá)標(biāo)排放，處理后的污水再排入城市污水管道。本設(shè)計(jì)對(duì)造紙廢水的處理具有一定的 借鑒意義。 本設(shè)計(jì)主要包括：設(shè)計(jì)說明 書（主要內(nèi)容有工藝流程設(shè)計(jì)、處理構(gòu)筑物和設(shè)備的設(shè)計(jì)計(jì)算、投資估算等）；設(shè)計(jì)圖紙（包括繪制平面布置圖、高程布置圖、管道布置圖和主要構(gòu)筑物詳圖等）。 關(guān)鍵詞： 造紙廢水 ； UASB+SBR 工藝；設(shè)計(jì) 西南科技大學(xué)本科畢業(yè)生論文 II The Design Of Treatment Plant Of Pulp And Papermaking Wastewater Abstract: Bee of high anic concentrations and suspended solids, the papermaking wastewater has been one mainly pollution source of water. And the method of anaerobic technology is adopted to treat papermaking wastewater by degrees. According to characteristics of papermaking wastewater, traditional wastewater treatment process and advanced EnergySaving device, this paper elects the joint UASB + SBR process to treat sewage: fiber is recycled from sewage by FiberRecycling machine, reentry adjustment pool of water and pH, and then carried out by the UASB anaerobic treatment, the following is to enter the SBR tank for aerobic treatment, through treatment, the wastewater can be discharged, treated and then discharged into the sewage pipeline. The design of wastewater treatment of paper making has a certain reference. This design include: the design specification (the design process mainly to deal with the design of structures and equipment, the investment estimates, etc.)。 design drawings (including floor plan drawing, elevation layout, piping layout and details of major structures such as ). Keywords: Papermaking wastewater, UASB + SBR Process, Design 西南科技大學(xué)本科畢業(yè)生論文 III 目錄 第 1 章 前言 .................................................................................................................... 1 造紙廢水的簡(jiǎn)介 ................................................................................................................... 1 引言 .............................................................................................................................. 1 造紙廢水處理的實(shí)際意義 ................................................................................... 1 國(guó)內(nèi)外研究現(xiàn)狀 ...................................................................................................... 1 處理工藝現(xiàn)狀 .......................................................................................................... 1 工程設(shè)計(jì)方案的選擇原則 ................................................................................... 3 設(shè)計(jì)概況 .................................................................................................................................. 4 設(shè)計(jì)名稱 .................................................................................................................... 4 設(shè)計(jì)內(nèi)容 .................................................................................................................... 4 設(shè)計(jì)主管單位 .......................................................................................................... 4 設(shè)計(jì)編制原則 .......................................................................................................... 4 工程技術(shù)采用的主要技術(shù)規(guī)范和標(biāo)準(zhǔn) ........................................................... 5 第 2 章 工程概況 ............................................................................................................. 6 設(shè)計(jì)的基本規(guī)劃 ...................................................................................................................... 6 處理方案的選擇 ...................................................................................................... 6 污水治理規(guī)劃與對(duì)策 ............................................................................................ 6 污水處理系統(tǒng)的設(shè)計(jì)規(guī)模 ................................................................................... 6 水質(zhì)目標(biāo) .................................................................................................................... 6 工程技術(shù)參數(shù) ......................................................................................................................... 7 設(shè)計(jì)規(guī)模 .................................................................................................................... 7 污水量變化系數(shù) ...................................................................................................... 7 設(shè)計(jì)水質(zhì)指標(biāo) .......................................................................................................... 7 設(shè)計(jì)水的排放效果 ................................................................................................. 7 污水的排放 ............................................................................................................... 7 廠址選擇 .................................................................................................................................. 7 西南科技大學(xué)本科畢業(yè)生論文 IV 廠址選擇條件 .......................................................................................................... 7 交通運(yùn)輸 和水電 ...................................................................................................... 8 第 3 章 工程計(jì)算 ............................................................................................................. 9 工程設(shè)計(jì) .................................................................................................................................. 9 處理工藝 .................................................................................................................... 9 工藝流程 .................................................................................................................... 9 工藝說明 .................................................................................................................... 9 處理水的去向 ....................................
