摘要
东北地区低温低浊地表水采用常规工艺难以净化处理 ,往往受到污染而使原水的色度、耗氧量提高 ,进一步增加了水质净化的难度 .另外 ,地表水体水质在一年中变化很大 ,采用固定的常规净化工艺很难适应 .对水处理工艺混凝、分离和过滤等环节进行了分析 。
Surface water at low temperature and low turbidity in China north-east area is difficult to treat, and difficulty is further aggravated owing to environmental pollution which results in a rise in color and oxygen demand in raw water. In addition, the significant variations of water quality in different seasons make it difficult to suit with a fixed conventional treatment process. Analyzed the coagulation, separation and filtration procedures in detail, and draw the conclusion that applying flotation-sedimentation tank can efficiently and economically treat surface water at low temperature and low turbidity.
