低温低浊地表水处理技术的探讨

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 ,得出了采用浮沉池工艺可以经济合理地处理低温低浊地表水的结论

Study on treatment technologies for surface water at low temperature and low turbidity

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.
