Water quality engineering is the main water supply and drainage engineering one of professional courses. It is an industrial and civil buildings provide the necessary production conditions and fortable, healthy and safe living environment for applied science. Course is designed to consolidate knowledge and practice engineering textbooks important means to design quality so everyone can directly reflect the level of understanding of the course. Is a water treatment plant in the city has played a decisive role in the development process units, water quality directly determines the production of urban residents living security, therefore, reasonable arrangements for water plant layout, scientific choice treatment structures are very necessary. In the design process, we will use a lot of water supply and drainage design manuals and professional design, through inspection about books, can understand the expertise did not know the individual39。 課程設(shè)計(jì)是鞏固 課本知識與聯(lián)系實(shí)際工程的重要手段，設(shè)計(jì)的好壞能直接反映大家對這么課程的理解程度。 水處理工程（一）課程設(shè)計(jì) 說明書 題 目： 某 凈水廠工藝設(shè)計(jì) 學(xué) 院： 市政與環(huán)境工程學(xué)院 專 業(yè)： 給水排水工程 I 前 言 水是人類生命的源泉，科學(xué)用水是人類社會發(fā)展史上最重要的社會活動和生產(chǎn)活動內(nèi)容之一，為保證人們能夠正常生活，供水系統(tǒng)就變的非常重要。凈水處理廠是一個在城市發(fā)展過程中起到?jīng)Q定性作用的單位，水質(zhì)問題直接決定了城市居民的生產(chǎn)生活的安全性，因此，合理的安排水廠布置，科學(xué)的選擇水處理構(gòu)筑物是非常有必要的。s capacity has been further improved. Involved in the design of a water treatment process, water control structures and structures and characteristics of elevation, water overall III arrangement, waterrelated issues encountered in the process, etc., because of the design of a preliminary design, so the design will appear some places unclear or erroneous instructions, they will continue their efforts to the maximum extent possible to make a qualified design specification.
