1、昆山市开发区净水厂设计 摘要：该区总体规划近期人口约为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，
2、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 Develo
