中文摘要：
以模拟铁超标的水源水作为研究对象，在水厂常规工艺的基础上增加预臭氧工艺，考察了该组合工艺对含铁原水的处理效果。结果表明，常规工艺对铁的去除效果有限；臭氧～沉淀工艺可以有效去除原水中总铁，原水中总铁含量为7．5～8．0mg／L时，臭氧投加量提高至5mg／L即可保证出水铁含量达标，但对浊度去除效果差。结合经济性原则，当原水总铁含量为5～8mg／L时，最佳工艺参数如下：O3投加量为4mg／L，PAC投加量为20mg／L；当原水中总铁含量为8～10mg／L时，最佳工艺参数如下：O3投加量为5mg／L，PAC投加量为20mg／L。
英文摘要：
Taking the simulated source water with excessive iron as the research object, pre-ozona- tion technology was added based on the conventional processes, and the treatment effect of Fe-containing raw water by the combined process was investigated. The results showed that iron removal efficiency of conventional processes was limited. Iron could be effectively removed by ozonation and sedimentation process, and when iron content in the raw water was 7.5 mg/L to 8.0 mg/L, and ozone dosage was 5 mg/L, the iron concentration in the effluent could meet the standard, but turbidity removal efficiency would be poor. Combined with the economy principle, when total iron content in raw water was 5 mg/L to 8 mg/L, the optimum process parameters were as 20 mg/L. When total iron content in raw water was 8 PAC was 5 mg/L and 20 mg/L respectively. follows： ozone dosage of 4 mg/L and PAC dosage of mg/L to 10 mg/L, the optimum dosage of ozone and
