Abstract: From the running instance of engineering, the design of suining county in Jiangsu province the ground water plant water supply project. Purification process is mainly design content for design and calculation of water works, including the determination of water flow, processing equipment calculation of frame and waterworks overall layout, then according to formulate water equipment instrument selection, determine the feasibility of the treatment process scheme, so as to determine the overall process. This design chooses polyaluminium chloride as a coagulant, choose chlorine disinfection, the effluent will be in accordance with the national standard "drinking water health standards" (GB5750-2006). Various equipment mainly calculated, according to the actual operational construction to determine the main structure size, design based on the size of the building material, determine the location of the equipment in the layout, so as to make overall layout, to map the related to structure sketch.
