Chlorella pollution is an important problem in the current water environment management. In recent years, various measures have been taken to control green algae. However, because the water body is open, there is no way to completely intercept the pollution source, so there is no way to completely avoid the problem of green algae in the water body, and can only maintain the nutrient balance in the water body as much as possible through continuous and effective maintenance, so as to reduce the possibility of large-scale green algae breeding, of course, there is a small area of green algae breeding, and it should also be treated in time.
Today, I would like to share with you the outbreak of green algae in the municipal park, and through the green algae emergency treatment products, the green algae have been effectively controlled and the beauty of the water body has been restored.
The water body of the artificial lake in the municipal park is divided into three parts: surface wetland, small lake area and large lake area. The water storage capacity of the Great Lakes is about 760,000 cubic meters, and the water storage of surface wetlands and small lakes is about 40,000 cubic meters.
Due to the high nutrient content of the reclaimed water and the unstable water quality, it flows into the lake for a long time, resulting in the enrichment of nutrients in the water body, which provides sufficient "nutrients" for the algae in the water** When the temperature is high every summer, the lake surface is prone to blooms, resulting in serious fishy odor and decreased water transparency, which affects the landscape effect of the water body.
According to the actual situation of the project and the treatment objectives, Bangyuan Environmental Protection adopts enhanced governance + effective maintenance, so as to control the outbreak of green algae.
1. Algae control in key pollution nodes
The use of green algae emergency treatment products EAMA-11 series of biological algaecides to inhibit cell protein synthesis, so that the normal metabolism of cells is terminated, algae growth is controlled, and algae are eliminated.
2. Comprehensive improvement of overall water quality
BPA-1017 series microbial water purifier is used to regulate and stabilize the microbial flora of the water body, improve the microbial diversity in the water, degrade the organic matter in the water, improve the transparency of the water body, and comprehensively improve the water quality.
After 30 days of bioremediation intensive treatment, the treatment goal was achieved:
1. Eliminate the green algae in the water body, inhibit the breeding of algae, and prevent the outbreak of blooms
2. The organic matter in the water is reduced, the transparency of the water body is improved, the small lake area is crystal clear, the transparency of the large lake area is maintained at more than 55cm, and the landscape effect of the water body is improved
3. It does not cause any impact on the fish and aquatic plants in the water body, and does not produce secondary pollution.
Due to the excessive nutrients brought in by the supplementary water every day, the water body needs to be maintained every day, and the overall water body is maintained well in the later water body maintenance stage, and the landscape effect of the water body is guaranteed.
EAMA-11 series biological algaecide can be used in the emergency treatment of green algae, water quality maintenance and prevention of green algae, which can effectively reduce the occurrence of large-scale outbreak of green algae.
