摘　　要：以南方某水库原水为处理对象,通过跟踪监测加压溶气气浮工艺和斜管沉淀工艺出水效果,对比分析两种工艺处理低浊、高藻水库原水的处理效能。结果表明,在加药量相同的条件下,压力溶气气浮工艺对藻类、浊度、Mn、CODMn、氨氮等指标的平均去除率分别为92.96%、75.50%、75.81%、57.99%、76.29%,而斜管沉淀工艺的去除率分别为83.77%、56.28%、53.34%、36.02%、54.29%,压力溶气气浮工艺对低浊、高藻水库原水的处理效能明显高于斜管沉淀工艺。This article focused on the raw water from a specific southern reservoir,comparing and analyzing the water treatment efficiency of the pressurized dissolved air flotation process and the inclined tube sedimentation process.The evaluation was based on tracking and monitoring the effluent efficiency of both processes in treating raw water with low turbidity and high algae reservoir content.Results indicated that under the same dosage conditions,the pressurized DAF process exhibits higher average removal rates for indicators such as algae,turbidity,Mn,CODMn,ammonia nitrogen and other indicators by the pressure dissolved air flotation process were 92.96%,75.50%,75.81%,57.99%,and 76.29%,respectively.The removal rates of the inclined tube sedimentation process were 83.77%,56.28%,53.34%,36.02%,and 54.29%,respectively.The treatment efficiency of the pressure dissolved air flotation process for low turbidity and high algae reservoir raw water was significantly superior to that of the inclined tube sedimentation process.
