A control system and method for controlling algae by cooling the surface of local water areas

Abstract

The invention relates to a partial water area surface cooling and algal inhibition control system which comprises a refrigeration system, a spraying conveying system and a green yarn alga preventing surrounding fence, wherein the green yarn alga preventing surrounding fence is arranged around a tap water taking hole; the refrigeration system comprises a shore-based refrigeration room; the spraying conveying system comprises a circulation conveying spraying device; the circulation conveying spraying device comprises a spraying conveying tube which is connected with the output end of the shore-based refrigeration room and a backflow tube which is connected with the input end of the shore-based refrigeration room; one end of the spraying conveying tube is connected with the shore-based refrigeration room; the other end of the spraying conveying tube is arranged in an encircling area of the green yarn alga preventing surrounding fence and forms an inner refrigeration area surrounding the tap water taking hole; an outer refrigeration area is formed between the spraying conveying tube forming the inner refrigeration area and the green yarn alga preventing surrounding fence; and spraying tubes are mounted on the spraying conveying tube forming the inner refrigeration area. By adopting the partial water area surface cooling and algal inhibition control system, the water temperature at the tap water taking hole can be reduced, blue-green algae can be effectively inhibited, and not only is the inhibition effect on blue-green algae improved, but also the whole system is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of cyanobacteria treatment, in particular to a cyanobacteria treatment system. Background technique [0002] At present, although the water quality of Taihu Lake has improved, the magnitude and extent of the improvement have shown "marginal effects". As far as the current situation is concerned, the water quality of Taihu Lake is improving more and more slowly, and there are even repeated outbreaks of blue-green algae. The outbreak of cyanobacteria in Taihu Lake began in 2008, and the investment in the treatment of cyanobacteria was large, but drugs were mainly used to inhibit the growth of cyanobacteria, such as adjusting P and N in the water. Inhibitory effect, after a long time, the drug will be washed away, and its effect will be greatly reduced. Since the ecological environment of algal lakes has not changed, when summer comes, when the water temperature reaches 22°C-25°C, there will still be outbreaks ...

[0002] At present, although the water quality of Taihu Lake has improved, the extent and degree of improvement have shown "marginal effects". As far as the current situation is concerned, the water quality of Taihu Lake is improving more and more slowly, and there are even repeated outbreaks of blue-green algae.

The outbreak of cyanobacteria in Taihu Lake began in 2008, and the investment in the treatment of cyanobacteria was large, but drugs were mainly used to inhibit the growth of cyanobacteria, such as adjusting P and N in the water. Inhibitory effect, after a long time, the drug will be washed away, and its effect will be greatly reduced. Since the ecological environment of algal lakes has not changed, when summer comes, when the water temperature reaches 22°C-25°C, there will still be outbreaks of blue-green algae, which seriously affects the Taihu Lake Water Quality
