【正文】 1 Abstract Acplish flocculation process flocculation pool (call reaction in general often pool) , handle middle in clean water occupying important position. Natural water suspension matter and limb matter grain diameter are very to dislodge these matter being backed by the means drifting along curdling generally , that is ,add the appropriate coagulant , blend through sufficiently in raw water, let colloid stability be spoiled the polymer (ing off after steady) and being situated between with coagulant water looks at and appraises an adsorption , makes a pellet have the flocculation function. But, that flocculation pool purpose is to create appropriate waterpower condition makes this have flocculation function pellet assembling, to form bigger flocculation body (catkin granule) in contacting middle mutually. But therefore, flocculation pool designs thinking that indeed or not, effect being related to a flocculation, the flocculation effect has direct impact to followup treatment precipitayion effect. The flocculation mixer is flocculation pool mechanical rabble device , it is used for the waste water treatment mixing process mainly. Design the design having mentioned flocculation pool originally, the mixer design and whose process flow. Keywords: Flocculation pool Coagulant Precipitayion effect Flocculation function 2 目 錄 第一章 緒論 ..................................................................................................................................... 1 論文研究的意義與現(xiàn)狀 ........................................................................................................... 1 畢業(yè)設(shè)計選題的意義 ............................................................................................................ 1 廢水處理的現(xiàn)狀 .................................................................................................................... 1 論文研究的主要內(nèi)容和安排 ................................................................................................. 1 攪拌機的作用與工作原理 ........................................................................................................ 2 絮凝的工作原理 ...................................................................................................................... 2 一般絮凝攪拌機的分類與組成 ................................................................................................ 3 絮凝攪拌機的適應(yīng)條件和構(gòu)造 ................................................................................................ 3 絮凝攪拌機的適應(yīng)條件 ......................................................................................................... 3 絮凝攪拌機的構(gòu)造 ................................................................................................................ 3 第二章 絮凝池的設(shè)計 ...................................................................................................................... 6 一般絮凝池的設(shè)計理論 ........................................................................................................... 6 反映時間與沉速的相關(guān)研究實驗 .......................................................................................... 8 絮凝池的設(shè)計要求及結(jié)果 ...................................................................................................... 15 第三章 攪拌機的設(shè)計 .................................................................................................................... 16 設(shè)計原始數(shù)據(jù) ........................................................................................................................ 16 設(shè)計要點 ............................................................................................................................... 16 設(shè)計計算數(shù)據(jù) ........................................................................................................................ 16 槳葉的設(shè)計 ............................................................................................................................ 17 槳葉尺寸的確定 .................................................................................................................. 17 攪拌器轉(zhuǎn)速的確定 .............................................................................................................. 17 攪拌功率的確定 .................................................................................................................. 18 電動機及減速器的選型 ......................................................................................................... 19 減速器和電動機的選型條件 ............................................................................................... 19 電動機與減速器的選擇 ....................................................................................................... 19 攪拌軸的設(shè)計及其結(jié)果驗證 .................................................................................................. 20 軸的設(shè)計 ............................................................................................................................. 20 上支撐裝置設(shè)計 .................................................................................................................... 22 機座的設(shè)計 ......................................................................................................................... 22 機座軸承裝置 ..................................................................................................................... 23 聯(lián)軸器的選擇與校核 .......................................................................................................... 24 鍵的選擇與校核 .................................................................................................................. 25 螺母螺母的選擇 .................................................................................................................. 26 3 水下支撐座的設(shè)計 ...................................................................................
