Method for controlling cyanobacteria

Abstract

The invention discloses a method for controlling cyanobacteria, and belongs to the technical field of environmental engineering. According to the method, an ecological restoration belt parallel to a levee is constructed at the downstream of the levee of a lake, cyanobacteria collecting ports are arranged on the ecological restoration belt every 300-500 m, the silt of the lake is injected into theecological restoration belt, and aquatic plants are planted in the ecological restoration belt; wind force and waves drive cyanobacteria to enter the port through the cyanobacteria collecting ports soas to conveniently salvage the cyanobacteria, such that the collecting area and the water content of cyanobacteria are effectively reduced, and the comprehensive management of cyanobacteria is achieved; and after a few years, the aquatic plants in the ecological restoration belt grow, the river course is formed, wild ducks and waterfowls play freely, and the ecological restoration belt becomes asightseeing and tourism scenic spot comprising green reed, rich grass, birds' twitter and fragrance of flowers and used for villagers and tourists, such that the water, the reed and the lake are integrated so as to truly achieve the harmony between human 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.
