摘　　要：针对原水微污染、存在富营养化风险、总氮指标偏高、嗅味等问题,在充分调研和论证的基础上,对常州魏村水厂现有生产工艺进行提质改造,增设以臭氧-生物活性炭为核心的深度处理工艺。项目通水后,出水水质符合《生活饮用水卫生标准》(GB 5749—2006),有机物去除效果明显提高,出厂水高锰酸盐指数最高质量浓度由2.00 mg/L降低至1.40 mg/L。本次改造工程实践中工艺总体方案、管道式投加预臭氧和深度处理工艺构筑物设计等,可供相似改造工程设计参考。Considering the problems of slight pollution, eutrophication risk, high content of TN, taste and odor, the conventional treatment process was reconstructed based on the ample research and demonstration, and the advanced treatment process of ozone-activated carbon process was added as the core. After the reconstruction, the finished water quality met the requirement of Standards for Drinking Water Quality(GB 5749—2006). The removal effect of organic in finished water was obviously improved, and the highest mass concentration of permanganate index was reduced from 2.00 mg/L to 1.40 mg/L. Overall process plan, pre-pipeline dosing of ozone, design of advanced treatment structures of this transformation project practice had a good reference for similar project design.
