摘　　要：针对某水厂内一组网格絮凝池-斜管沉淀池-重力式无阀滤池-清水池常规处理工艺,通过中试研究和方案比选,最终确定采用以浸没式超滤膜为核心的网格絮凝-斜管沉淀-膜过滤的水处理工艺流程,扩建和改造原处理设施,工程实践证明改扩建后具有较好的运行效果。An upgrading project needed to be carried out on a water treatment plant with the traditional water treatment process of grid flocculating tank-inclined tube settling tank-gravity valveless filter-clean water tank. Based on a pilot test and process comparison, it was decided that the water treatment process of grid flocculating tank-inclined tube settling tank-membrane filter with the central part of submerged ultrafiltration membrane was used for the reconstruction and upgrading of former facilities. The engineering practice showed that the operation performance was satisfying after the upgrading project.
