中文摘要	通过中试试验确定了高藻条件下溶气气浮的最优强化混凝条件:pH6.60,碱式氯化铝投加量为2.0mg/L(以Al计),在此条件下,气浮工艺出水浑浊度为0.30NTU,UV254的去除率为33.3%,耗氧量的去除率为45.0%,藻的去除率为94.2%。试验显示,投加H2SO4改变原水pH对浑浊度去除的影响不显著,对UV254、耗氧量和藻去除效果的影响显著。; The pilot experiments were conducted during the treatment of high algae-laden raw water with Dissolved Air Flotation (DAF), and the best enhanced coagulation conditions were obtained with pH at 6.60 and the flocculants dosage of AlCl3 at 2.0 mg/L. Under the enhanced coagulation conditions, the turbidity in the effluent was 0.30 NTU, the removal efficiency of UV254 was 33.3%, the removal efficiency of oxygen comsumption(OC) was 45.0%, and the removal efficiency of algae was 94.2%. The results showed that the dosing of H2SO4 for pH adjustment had little effect on turbidity removal, but had obvious effect on the removal of UV254, OC and algae.
