摘　　要：对密云水库水采用溶气气浮(DAF)工艺进行处理,发现DAF工艺处理密云水库水效果显著.在高藻期,DAF工艺对藻类的去除效果明显,在原水温度t=13.8～20.1℃,pH=6.6,ρ(Al3+)=2.0 mg/L的最优混凝条件下,进水浊度为2.62～5.93 NTU,出水浊度为0.29～0.44 NTU,色度去除率为81.8%,嗅阈值去除率达75.0%,藻总数去除率达92.6%.It was found in the treatment of the water from Miyun reservoir by Dissolved Air Floatation (DAF) process that the result of the treatment of the said water by the said process was significant. During algae-laden period, the result of removal of algae by DAF process was obvious. When the raw water was under the optimum coagulating conditions, i.e., t = 13.8 ~ 20.1℃, pH = 6.6 and ρ(Al3+)= 2.0 mg/L, and when the turbidity of the inlet water was 2.62 ~ 5.93 NTU, the turbidity of the outlet water was 0.29 ~ 0.44 NTU, the removal rate of colour was 81.8%, the removal rate of olfactory threshold value reached 75.0% and that of total algae number reached 92.6%.
