摘　　要：以南方某水库水为处理对象,探讨了预臭氧化的效果及其适用条件.研究发现,当臭氧量≤0.5 mg/L时,预臭氧化对粒径＞2μm的颗粒物、CODMn、UV254等的去除均有显著的促进作用,投量过高反而会造成沉淀出水水质恶化;只有当原水浊度较高时,预臭氧化才显示出对浊度去除的促进作用.生产性试验结果表明,臭氧投量为1.5 mg/L时的除浊效果明显劣于投量为0.5～1.0 mg/L时的除浊效果.Discussion was made on the effect of pre-ozonation on treatment of reservoir water and its applicable conditions in South China. It is observed in the study that pre-ozonation has obvious effect on removal of the particles with size above 2 μm, COD_(Mn), and UV_(254) under ozone dosage ≤0.5 mg/L. However, excessive dosage will lead to deterioration of treated water. Only when raw water has higher turbidity, can the pre-ozonation help with the turbidity removal. Large-scale experiment result shows that turbidity removal effect at ozone dosage of 1.5 mg/L is inferior to that at dosage of 0.5-1.0 mg/L.
