Abstract

Water plant is an important urban service infrastructure, which is directly related to people's life and production. According to the original data of the design specification, the design of the water supply project of the eastern new town of Anqing City, Anhui Province is carried out. The scope of engineering design includes three parts: water plant, pump station and pipe network. The scale of the water plant is 100000 m³/day, and the water source is the Yangtze River. According to the water quality of the water source, through scheme comparison and selection, it is determined that the water purification process of coagulation, sedimentation, ozone oxidation, activated carbon adsorption, filtration and disinfection and the structure form of each treatment unit are adopted in the water plant, that is, the raw water enters the mechanical flocculation tank, inclined plate sedimentation tank, ozone contact tank, upflow activated carbon filter, ordinary fast filter through the tubular static mixer, and then enters the clean water after being disinfected by liquid chlorine The water pool enters the urban water supply network from the secondary pump station. The circular network is adopted in the water supply network, which ensures the reliability of water supply, and strives for the shortest distance of pipeline, saving economy. The main contents of this design include: water supply pipe network design, water pump and pump station design, water purification process scheme comparison and selection and structure design, sludge discharge treatment design, water plant layout, process elevation layout, production pipeline, drainage pipeline, rainwater and sewage pipeline layout, etc.

Key words: Water purification plant; pipe network; advanced ozone activated carbon treatment；conventional water treatment
