【正文】 西南科技大學本科畢業(yè)生論文 I 制漿造紙廢水處理站的設計 摘要： 造紙 廢水已成為 水體污染 重要 污染源。該類廢水有機物濃度高、懸浮物多，因此厭氧技術成為造紙廢水處理中不可缺少的關鍵技術。 結合造紙廢 水的水質(zhì)特點及傳統(tǒng)廢水處理工藝，本設計 把成熟處理方法和先進技術以及節(jié)能裝置相結合， 選用 UASB+SBR 的聯(lián)合處理工藝 ， 污水經(jīng)過纖維回收機，再進入調(diào)節(jié)池調(diào)節(jié)水量及 pH，再由 UASB 進行厭氧處理，后進入 SBR 池進行好氧處理，通過處理，該廢水可達標排放，處理后的污水再排入城市污水管道。本設計對造紙廢水的處理具有一定的 借鑒意義。 本設計主要包括：設計說明 書（主要內(nèi)容有工藝流程設計、處理構筑物和設備的設計計算、投資估算等）；設計圖紙（包括繪制平面布置圖、高程布置圖、管道布置圖和主要構筑物詳圖等）。 關鍵詞： 造紙廢水 ； UASB+SBR 工藝；設計 西南科技大學本科畢業(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 西南科技大學本科畢業(yè)生論文 III 目錄 第 1 章 前言 .................................................................................................................... 1 造紙廢水的簡介 ................................................................................................................... 1 引言 .............................................................................................................................. 1 造紙廢水處理的實際意義 ................................................................................... 1 國內(nèi)外研究現(xiàn)狀 ...................................................................................................... 1 處理工藝現(xiàn)狀 .......................................................................................................... 1 工程設計方案的選擇原則 ................................................................................... 3 設計概況 .................................................................................................................................. 4 設計名稱 .................................................................................................................... 4 設計內(nèi)容 .................................................................................................................... 4 設計主管單位 .......................................................................................................... 4 設計編制原則 .......................................................................................................... 4 工程技術采用的主要技術規(guī)范和標準 ........................................................... 5 第 2 章 工程概況 ............................................................................................................. 6 設計的基本規(guī)劃 ...................................................................................................................... 6 處理方案的選擇 ...................................................................................................... 6 污水治理規(guī)劃與對策 ............................................................................................ 6 污水處理系統(tǒng)的設計規(guī)模 ................................................................................... 6 水質(zhì)目標 .................................................................................................................... 6 工程技術參數(shù) ......................................................................................................................... 7 設計規(guī)模 .................................................................................................................... 7 污水量變化系數(shù) ...................................................................................................... 7 設計水質(zhì)指標 .......................................................................................................... 7 設計水的排放效果 ................................................................................................. 7 污水的排放 ............................................................................................................... 7 廠址選擇 .................................................................................................................................. 7 西南科技大學本科畢業(yè)生論文 IV 廠址選擇條件 .......................................................................................................... 7 交通運輸 和水電 ...................................................................................................... 8 第 3 章 工程計算 ............................................................................................................. 9 工程設計 .................................................................................................................................. 9 處理工藝 .................................................................................................................... 9 工藝流程 .................................................................................................................... 9 工藝說明 .................................................................................................................... 9 處理水的去向 ....................................
