Abstract

The invention is about a system unit for treating the lake water and controlling the growth of the alga. The unit includes the inlet pool, the discharge bay and the filter layer. The method is to adjust the pH using the CO2 to inhibit the growth of the alga. The unit has the high overflow and stable structure.

Description

Technical field [0001] The invention relates to a system unit for purifying lake water and effectively controlling the growth of algae in the water and its usage. Background technique [0002] Water is the source of life, the basic condition for human survival, and an important resource for economic and social development. On June 5, 2003, the 31st World Environment Day, the United Nations Environment Programme identified the theme as "Water-where human life is tied." People all over the world who care about the environment have turned their attention to the intimate relationship between "people and water". [0003] my country's per capita water resources are among the thirteen lowest countries in the world. Among the 660 cities above the county level, more than 400 cities suffer from water shortages. [0004] Lakes are the largest source of fresh water supply, but at present, as many as 85% of lakes in different eutrophication states in my country, lake eutrophication, especiall...
