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 parison 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 panies 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 multibarrier 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 哈爾濱工業(yè)大學(xué)畢業(yè)設(shè)計（論文） III 目 錄 摘 要 ......................................................................................................................
