| 摘 要： | 针对引黄水库水的特点,采用臭氧预氧化强化常规工艺处理引黄水库水。中试研究结果表明:臭氧预氧化能够降低常规工艺出水浊度,改善对有机物的去除效果,同时提高常规工艺对氨氮和藻类的去除率。适宜的臭氧投加量为1～2mg/L,当臭氧投加量为1mg/L时,臭氧预氧化后,滤后水浊度、CODMn、UV254、氨氮和叶绿素a的去除率,与常规工艺相比分别提高了2.7,2.5,7.8,5.2和4.8个百分点。

| Abstract: | Considering the characteristics of the reservoir water from the Yellow River,the ozone preoxidation for enhanced conventional process was applied on the water treatment.The results of pilot-scale study showed that the ozone preoxidation could improve the quality of treated water compared with a conventional process,which could reduce turbidity,and improve the removal of organic compounds,NH3-N and algae as well.The appropriate ozone dosage was 1～2 mg/L,and when the ozone dosage was 1 mg/L,the removal rates of turbidity,CODMn,UV254,NH3-N and chlorophyll a could be increased by 2.7,2.5,7.8,5.2,and 4.8 percentage points,respectively. |
