摘要 随着城市供水水质要求的提高及供水量需求的不断上升,老旧水厂节地改造已成为目前国内的普遍性问题。针对合肥市某水厂的供水量增产需求,采用侧向流斜板沉淀工艺对该水厂的4#混凝沉淀池进行提标改造。生产运行结果表明,在低浊微污染水库原水水质条件下,该工艺可在不增加用地面积的情况下,改造提升老旧平流沉淀池的出水水质及水量,并显著降低净水剂单耗。因此,侧向流斜板沉淀工艺可在老旧平流沉淀池改造工程中进行推广应用。 With the improvement of water quality requirement and increased of water quantity,the land-saving reconstruction of aging water treatment plant(WTP)has become a common issues at home.According the increasing demand for water supply of a WTP in Hefei City,side-flow lamella sedimentation process is used to reconstruct the 4#flocculation sedimentation tank.The operation results show that,under low turbidity micro-pollution reservoir raw water condition,side-flow lamella sedimentation process could improve the water quality and quantity of aging horizontal-flow sedimentation tank without increasing the total site area,and also reduce the consumption of flocculant.Side-flow lamella sedimentation process could be widely applied in the reconstruction projects of aging horizontal-flow sedimentation tanks.
