摘　　要：针对源水受到污染,藻类含量过高、总氮超标、嗅味以及亚硝酸盐超标等问题,在充分论证的基础上,对原有常规处理工艺进行了提升改造。采用臭氧-活性炭工艺,充分利用了原有构筑物,将平流沉淀池改造为气浮-斜管沉淀复合池,提高了处理水量。改造后解决了水厂原有工艺存在的工艺滞后、部分构筑物超负荷运行等不足,出水水质符合《生活饮用水卫生标准》(GB5749—2006)。Considering the problems caused by the pollution, such as the high content of algae, TN exceeding the standard, the taste and odor and the nitrite exceeding the standard, the original con ventional treatment process was reconstructed based on the ample demonstration. The ozone/activated carbon process was used, the original structures were fully used, the horizontal flow sedimentation tank was reconstructed into the airfloatation/inclinedtube sedimentation tank, and the treatment capacity was increased. After the reconstruction, the problems of original treatment process, such as the process lag, overload operation of some structures and so on were solved. The finished water quality met the require merit of the Standards for Drinking Water Quality （ GB 5749 - 2006）
