摘　　要：为保证高藻水情况下的供水水质,天津市芥园水厂进行了第4次改造,拆除了斜管沉淀池和双向滤池,保留了平流沉淀池、快滤池和双阀滤池,新建了一座综合净化间(包括进水室、机械絮凝池、气浮池、气水反冲洗滤池、加药间、石灰间、反冲洗排水池、变配电及控制室等建构筑物)。改造后水厂的供水能力达到50×104m3/d,出水浊度为0.5NTU。In order to ensure the quality of supply water under the high algae-laden situation, the fourth technical reconstruction was performed in Tianjin Jieyuan Water Treatment Plant. The tube settler and biflow filter were removed, the horizontal sedimentation tank, rapid filter and double-valve filter were kept, and a new comprehensive clean room including intake chamber, mechanical flocculator, floatation tank, air-water backwashing filter, chemical addition chamber, lime chamber, backwashing drainage tank, control room for power transformation and distribution and other structures was constructed on the east part of this plant. After the reconstruction, the plant has a water supply capacity of 50×10^4m^3/d, and the effluent turbidity is 0.5 NTU.
