工藝。在逐漸認(rèn)識(shí)到飲用水存在水質(zhì)污染和危害的同時(shí),人們也開始了長(zhǎng)期不懈地對(duì)飲用水凈化技術(shù)的研究和應(yīng)用。 給水處理的主要任務(wù)和目的就是通過(guò)必要的處理方法去除水中的雜質(zhì),以價(jià)格合理、水質(zhì)優(yōu)良安全的水供給人們使用,并提供符合質(zhì)量要求的水用于工業(yè)。但從 總體看我國(guó)給水工藝與世界先進(jìn)技術(shù)相比還有一定距離。 給水處理工程:凈水廠場(chǎng)址選擇、水處理方案的比較與選擇、工藝流程、總平面布置 (包括主要輔助建筑物,給排水管道,道路、綠化、沖洗水、排泥水回收等 ),各建構(gòu)筑物型式、尺寸及設(shè)備選擇,選擇,投藥、消毒,新工藝及新型構(gòu)筑物采用原理及效果的設(shè)計(jì)計(jì)算并繪圖。掌握設(shè)計(jì)說(shuō)明書、計(jì)算書的編寫內(nèi)容和編制方法,并繪制工程圖。對(duì)取水工程、凈水工程與輸配水工程進(jìn)行設(shè)計(jì)。slanting canal preciplitank。 water treatment project。 通過(guò)技術(shù)和經(jīng)濟(jì)比較,確定凈水廠的工藝流程選用方案一: 方案一:太湖水 一級(jí)泵房液氯聚合鋁網(wǎng)格絮凝斜管沉淀池 無(wú)閥濾池 無(wú)閥濾池 清水池 二泵房 城市管網(wǎng)液氯 關(guān)鍵詞: 取水工程;輸配水工程;凈水工程; 網(wǎng)格絮凝池;斜管沉淀池;無(wú)閥濾池; Abstract The design is water supply project for the water plant of PuZhuang town of SuZhou City in Jiangsu Province. The total volume of this project is 10 thousand cubic meters. The whole project consists of three parts which is water diversion project, water transport and allocation project and water treatment project. The surface water diversion project consists of the selection of water source location, the form of water diversion and the design of pump station. The water clarification project is the major part in this paper. It consists of the choice of the water plant location, processes selection, water treatment constructions design, plant layout and architectural design. This paper also demonstrates the detail of process of design for each construction or apparatus in the water treatment plant. It is divided into two parts: water treatment plant designing and water proportioning plant designing. According to the surveying about quality of raw water, the raw water can be transmitted to the user only through simple disinfection (add chlorine). Two sets of program have been pared both technologically and economically. And the first program is preferred. The whole process is as follows: raw water→ pipeshaped mixing apparatus →mechanical stirring clarifier → water treatment project→ flocculent tank→ nonvalve filter →clear well→ highservice pumping station→ municipal pipe work. Keywords: water diversion projects。 凈水工程的主要設(shè)計(jì)內(nèi)容為凈水廠的設(shè)計(jì)計(jì)算。 整個(gè)工程包括三大部分:取水工程、輸配水工程和凈水工程。 揚(yáng)州大學(xué)環(huán)境科學(xué)與工程學(xué)院 畢 業(yè) 設(shè) 計(jì) 專 業(yè) 給水排水工程 班 級(jí) 學(xué) 生 姓 名 完 成 日 期 2021 年 6 月 11 日 指 導(dǎo) 教 師 評(píng)閱 人 揚(yáng)州大學(xué)畢業(yè)設(shè)計(jì) 摘 要 本設(shè)計(jì)為江蘇省蘇州市浦莊鎮(zhèn)二期擴(kuò)建工程設(shè)計(jì)。該工程水量目標(biāo),預(yù)計(jì)水廠的總規(guī)模為 1*104m3/d。 取水工程主要的設(shè)計(jì)內(nèi)容為地表取水位置的選擇、取水型式的確定及取水泵站的設(shè)計(jì)。包括水處理工藝流程的確定、處理構(gòu)筑物的設(shè)計(jì)計(jì)算以及水廠的平面和高程布置。 water transport and allocation projects。flocculent tank。 nonvalve filter 目 錄 緒 論 .................................................................................................................................... 1 1 概 況 .................................................................................................................................... 6 設(shè)計(jì)任務(wù) ...................................................................................................................... 6 設(shè)計(jì)原則 ...................................................................................................................... 6 設(shè)計(jì)原始資料 .............................................................................................................. 6 2 供水方案設(shè)計(jì) ........................................................................................................................ 8 水源選擇 ....................................................................................................................... 8 取水點(diǎn)及取水構(gòu)筑物型式確定 ................................................................................... 8 廠址選擇 ....................................................................................................................... 9 水廠工藝流程確定 ....................................................................................................... 9 水處理構(gòu)筑物型式選擇確定 ..................................................................................... 14 凈水廠總體布置 ......................................................................................................... 16 3 供水方案設(shè)計(jì) ...................................................................................................................... 20 給水處理廠用水量設(shè)計(jì) ............................................................................................. 20 投藥系統(tǒng) ..................................................................................................................... 20 加氯系統(tǒng) ..................................................................................................................... 21 網(wǎng)格絮凝池設(shè)計(jì) ......................................................................................................... 22 斜管沉淀池設(shè)計(jì) ......................................................................................................... 27 半敞開式無(wú)閥濾池 ..................................................................................................... 32 清水池 ......................................................................................................................... 38 取水工程設(shè)計(jì) ............................................................................................................. 40 二級(jí)泵房 ..................................................................................................................... 43 系統(tǒng)高程設(shè)計(jì) ........................................................................................................... 46 平面布置 ................................................................................................................... 48 致 謝 ........................................................................................................................................ 49 參考文獻(xiàn) .....................................................................................
