摘　　要：南宁市五象水厂取水泵房及原水管一期工程设计规模为30万m^(3)/d,采用自流管式固定取水构筑物,主要建设内容为取水头部、引水管、取水泵房、应急加药间、值班室(含仓库)、原水管道。取水头部采用分层取水型式,可保证在不同季节及不同水位时取水水量和水质满足设计要求;引水管采用4根,自流引水,引水管切换阀门设置在泵房内,便于切换操作;通过在4根引水管设置次氯酸钠投加管,定期投加次氯酸钠避免水生植物及贝壳类在管道内生长;应急加药间内设置粉末活性炭及高锰酸钾投加设施,在水源发生突发性污染时投加。The design scale of Nanning Wuxiang Water Plant Water Intake Pump House and Raw Water Pipe Phase I Project is 30000 m^(3)/d.The fixed water intake structure adopts a self flowing pipe type,and the main construction content includes the water intake head,water intake pipe,water intake pump room,emergency dosing room,duty room(including warehouse),and raw water pipeline.The water intake head adopts a layered water intake type,which can ensure that the water intake volume and quality meet the design requirements in different seasons and water levels;Four water diversion pipes are used for self flow water diversion,and the switching valve of the water diversion pipe is set in the pump room for easy switching operation;By setting Sodium hypochlorite feeding pipes in the four water pipes,Sodium hypochlorite is regularly added to prevent Aquatic plant and shells from growing in the pipes;Powdered activated carbon and Potassium permanganate dosing facilities are set in the emergency dosing room to dosing in case of sudden pollution of water source.
