In particular, modern, with the acceleration of urbanization, water and wastewater engineering has bee an important urban infrastructure construction and industrial development, security and human health became industrial and agricultural science and technology development and production, but also the talent to develop into higher education cultured important areas of expertise. Water Supply and Drainage Water Supply project is posed of two parts and drainage works, water supply and drainage pipeline project is a major ponent of water supply and drainage works, and its construction investment accounted for about 70% of the total investment in water supply and drainage works, water supply and drainage has long been highly construction, management, operations, and research departments attach great importance. Water supply and sewer systems throughout the entire engineering process water and wastewater engineering and engineering aspects and links to all the channels and link objects, water supply and sewer system piping system in function and sequence although different, but both before and after the construction has always been carried out in parallel The. As engineering students, handson learning and design our own knowledge and experience to get the best link. Students through the design, the integrated use of the basic theory and deepen learning, basic skills, to develop our independent analysis and problemsolving ability, through the design enables us to have the ability to consult Method Standard Design Atlas, product catalog, improve puting, drawings and written description of the design level, prepare a basic training engineers. Skilled detailed calculations town water supply and drainage system and the ability to develop certain theoretical analysis and design. Demonstrate the ability to analyze and improve the overall parison, technical and economic, environmental, social and other aspects of the program. The ability to develop puter operations and applications. Skilled professional software applications. 目 錄 第一章 課程設計任務書 .............................................................................................. 1 第二章 給水管網(wǎng)設計和計算 ...................................................................................... 3 給水管網(wǎng)布置及水廠選址 ............................................................................. 3 給水管網(wǎng)設計計算 ......................................................................................... 3 管網(wǎng)水力計算 ................................................................................................. 7 二級泵站 ....................................................................................................... 14 消防校核 ....................................................................................................... 14 第三章 污水管網(wǎng)設計與計算 .................................................................................... 16 污水設計流量計算 ....................................................................................... 16 污水管道水力計算 ....................................................................................... 17 第四章 雨水管網(wǎng)設計與計算 .................................................................................... 19 雨水管網(wǎng)設計流量 ....................................................................................... 19 雨水管道設計參數(shù) ....................................................................................... 19 雨水管道水力計算 ....................................................................................... 20 設計總結(jié) ...................................................................................................................... 22 附表一 .........................................................................................
