A method of controlling blue-green algae

Abstract

The invention discloses a method for controlling cyanobacteria, which belongs to the technical field of environmental engineering. The method is to build an ecological restoration belt parallel to the embankment at the downstream of the embankment of the lake, and the ecological restoration belt is set every 300-500 meters. The cyanobacteria collection port, and then inject the silt in the lake into the ecological restoration zone, and plant aquatic plants in the ecological restoration zone, thus forming a wetland aquatic plant belt along the lake; the cyanobacteria enter the port through the cyanobacteria collection port driven by wind and waves, which is convenient Cyanobacteria salvage effectively reduces the collection area and water content of cyanobacteria, and realizes the comprehensive management of cyanobacteria. A few years later, the aquatic plants in the ecological restoration belt will grow, the river will be formed, and the wild ducks and waterfowl will play freely. The ecological restoration belt will become a sightseeing and tourist scenic belt for villagers and tourists. The integration of water, reeds and lakes truly achieves harmony between man and nature.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to a method for controlling cyanobacteria. Background technique [0002] In recent years, my country's water pollution situation has become increasingly serious, and some lakes under national key monitoring have prominent problems of eutrophication and frequent cyanobacteria blooms. The outbreak of cyanobacteria not only leads to the degradation of the structure and function of the lake ecosystem and the reduction of biodiversity, but also seriously affects the normal production and life of the people, threatens the safety of drinking water, and has a great negative impact on the tourism industry. [0003] 1. The nature of cyanobacteria [0004] Cyanobacteria are cyanobacteria, also known as blue-green algae. It is one of the most primitive and ancient algal plants. Its main features are: simple plant body, unicellular, various groups and filaments; ...

[0015] In recent years, many scientific researchers have conducted a lot of research on the control of blue-green algae, and have also explored several effective methods, but they are always treating the symptoms, not the root cause.
