毕业设计-昆山市开发区净水厂设计.doc

昆山市开发区净水厂设计 20万人，远期有将达30万人，年工业产值为15亿元，远期将达34亿元。开发区发展方向主要是积极发展区东区并向北、向南适当发展。该区设有纺织、轻工、食品、化工、机械电子、建材、服装、皮革等区、乡、镇属工业、企业近200家，其中中外、中港合资企业4家，新开发 区已有11家企业投产，正在形成一个新型工区并将成为该区的经济中心。净水厂供水范围主要是解决新开发区的用水。 主要包括取水工程与净水工程，主要内容如下： 1 用水量计算：编制总用水量计算表，确定设计规模（近、远期）； 2 给水系统的选择和给水方案的比较：选择水源与取水方式，确定净水厂厂址和净水工艺，提出可行的给水方案并进行比较； 3取水工程设计：确定净水厂厂址和净水工艺，提出可行的给水方案并进行方案比较，设计取水构筑物，取水枢纽布置； 4净水厂设计：净水构筑物的选择与工艺设计，净水厂总体布置（平面及高程） 5泵房设计：确定水泵工况，选择水泵型号及台数，进行泵房工艺布置。 随着该开发区经济的迅速发展，人口的大量增加，工业用水及居民生活用水量大幅度提高，现有的供水量已远远不能满足增长的要求，供需矛盾日益突出，同时现有的水厂水源地北环城河受到严重污染，水质恶化，所以水厂的建设迫在眉睫，本工程完成之后，可以大大缓解上述矛盾。 关键字： 用水量 工艺设计 方案比较 泵房 管网设计 Kunshan Development Zone water purification plant designAbstract: The overall planning area population of about 20 million people, forward will reach 30 million, the annual industrial output value of 15 billion yuan, forward will reach 34 billion yuan. Development Zone, the main direction of development is a positive development area Eastern and north, south proper development. Area of ??the district is served by the textile, light industry, food, chemicals, machinery and electronics, building materials, clothing, leather, township and town is an industrial, nearly 200 enterprises, including foreign, Hong Kong joint venture of four new development11 went into operation, and will become the economic center of the area is the formation of a new work area. Water purification plant water supply coverage is mainly water to solve new development zone.The Development Zone is located at latitude 30 ° 23 ', longitude 125 ° 57', located in the middle and lower reaches of the alluvial plain. Verge of Taihu Lake, located in the eastern part of Jiangsu Province, Shanghai, east, west, Suzhou, Shanghai-Nanjing Railway and the Trans territory of the river criss-cross, lakes, land and water transportation is very convenient, the city is a city with more than two thousand years of history of the southern city. Of the region is broad and flat, ground elevation is generally 1.3-1.9m, local area 2.5-3.0m, the
