摘要
水是人民生活和社会生产必需的基本资源之一。合理开发利用水资源，实现水资源优化配置、有效保护与安全供给，对于促进经济社会发展、提高人民生活水平和保障国家安全均具有重大的战略意义。因此，作为给排水工程技术人员，面临着艰巨的任务和巨大的挑战。
本设计为东北地区D城市给水工程，设计内容包括以下方面：
（1）城市给水管网设计及方案的选择比较；
（2）取水工艺设计；
（3）净水厂工艺设计及构筑物结构设计；
（4）二泵站工艺设计；
（5）工程总概算。
目前，随着科技的进步，供水行业需要建立新型的水质观及高效的饮用水水质保障体系。强化单元工艺及多级屏障技术是十分有效的保障手段。本设计在常规工艺的基础上，增设臭氧预氧化单元，用以强化混凝效果；同时对过滤单元进行强化，采用国内外最先进的翻板滤池，使滤后水的浊度大大降低，保证了出厂水的安全性。

Abstract
Water is one of essential resources for people’s life and social production. Some strategies including utilizing the water resource reasonablely, arranging the water resource optimally, protecting the water resource effectively and supplying the water resource safely make great contributions to the development of economic society, the improvement of people’s life and the protection of national safety. Hence, as an engineer of water supply and drainage engineering, I will confront arduous tasks and great challenges.
The title of my undergraduate design is D city’s water supply engineering in northeast China, and it includes several aspects:
(1) The design of water distribution system and the comparison of two schemes;
(2) The design of intake station;
(3) The design of drinkable water treatment plant;
(4) The design of pump station;
(5) General estimate of the water supply project.
Nowadays, with scientific and technical development, water supply companies need to form a new conception of water quality and establish new effective protective system of drinkable water. Accoding to the data of researches and projects, the intensified unit process and multi-barrier process are considered to be effective methods to protect the water quality. In my design, I not only added an ozone pretreatment process in order to strengthen the effect of coagulation, but also intestified the filtration process via introducing shutter filter to descrease the turbidity of filter effluent and assure the safety of water supply.
Keywords water distribution system; portable water treatment process; ozone pretreatment; shutter filter; general estimate of the water supply project
