Embodiment 1

[0058] On the southwestern bank of Dianchi Lake, build 10 system units of the present invention as shown in Figure 1.

[0059] The depth of the water inlet pool 1 and the water outlet pool 2 of each system unit is 4 meters, and the bottom area is 4 meters x 12 meters;

[0060] At 3 meters above the water inlet pool 1, an air-water mixing device 5 as shown in Figure 1 is fixed. The opening of the air-water mixing device 5 is downward and below the liquid surface. Its specifications are square, with a side length of 1.5 meters and a height of 80 cm. .

[0061] The height of each filter layer is equal, and the total height is 1.5 meters. The filling filter material is: coarse filter material layers 11 and 15 are ceramsite with a particle size diameter of 2cm-4cm, and medium filter material layers 12 and 14 are river sand with a particle size of 40 mesh, fine The filter material layer 13 is river sand with a particle size of 170 meshes; the uppermost filter layer is covered with ...

Embodiment 2

[0070] On the southwestern bank of Dianchi Lake, build 10 system units of the present invention as shown in Figure 1.

[0071] The depth of the water inlet pool 1 and the water outlet pool 2 of each system unit is 4 meters, and the bottom area is 7 meters x 9 meters;

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 Program determined the theme to be "Water - the essence of human life". People all over the world who are concerned about the environment are focusing on the intimate relationship between "people and water". [0003] my country's per capita water resource is one of the thirteen countries with the lowest in the world. Among the 660 cities above the county level in the country, more than 400 are short of water resources. [0004] Lakes are the largest source of fresh water supply, but at present, as many as 85% of lakes are in different eutrophic states in my country. The eutr...
