Research On The Technical Scheme Selection And Design Of Water Supply Project In Tuandong

The project scale of the water supply project in the turbulent eastern district of neixiang county is 30,000 tons/day.The project consists of 20 kilometers of pipeline engineering,water purification plant engineering and urban water supply pipe network project.According to the investigation,the engineering water pipe line is selected by three schemes,and DN800 reinforced concrete pipe is used for pipe selection.The water transmission pipeline shall be equipped with the addition of medicine and anti-algae,and the exhaust and maintenance facilities shall be set.The main source of water in the reservoir is 20 kilometers away from the water plant,and the nearby river is the second source of water.Water treatment works to choose"conventional coagulation precipitation + filtration + disinfection" process,based on local water conditions,on the basis of sufficient investigation and research,in order to ensure the quality of water treatment,on the basis of focus on improve the efficiency of water treatment.The coagulation is mixed with a tubular static mixer,perforated swirl flocculation pool;The urban water supply pipe network is calculated according to the urban planning,and the main pipeline is reasonably arranged,which is better than the new environmental protection pipe.The pipe diameter of ND400 and above is made of nodular cast iron pipe,and PE water supply pipe is adopted for the ND400 and the following pipe diameters.
