Abstract Objective To find out the reasons of abnormal pH value of raw water in Shang lake and to deal with them by prop-

er measures. Methods Based on the field investigation the relation of pH value with climate dissolved oxygen total hardness
,
total alkalinity the number of algae of Shang Lake during 2007 and 2008 were analyzed. Results In the east areas of Shang
, ,
Lake the strong photosynthesis of multiplying submerged plants led raw water pH value to increase abnormally and restrained the
,
growth of algaes. Conclusion The multiplying of submerged plants purified the raw water quality. In water plant the raw water
,
pH value was adjusted to normal level by adding hy
