Problems solved by technology

However, the mesh required to salvage algae is too small and the water content is too high. From a commercial point of view, the cost of salvage is higher than the value of organic fertilizers
[0007] As we all know, water plants (such as water hyacinth, water peanut, water floating lotus, including water vegetables, water flowers, etc.) can indeed absorb nutrients in the water body, but they block the water surface and cover the sunlight, causing some underwater organisms and mud bottom organisms to In particular, the death of submerged plants will cause a large amount of dissolution of nutrients in the sediment, and their disadvantages far outweigh their benefits

Embodiment Construction

[0017] The present invention is a kind of water body ecological restoration method, comprises the following steps:

[0018] (a) taming a zooplankton to feed on cyanobacteria in polluted water bodies as algae-eating insects, and

[0019] (b) release the algae-eating insect into the water body polluted by cyanobacteria, wherein the algae-eating insect feeds on the blue-green algae in the water body polluted by cyanobacteria, thereby purifying the water body and restoring the ecological balance of the water body.

[0020] We all know that there is no existing plankton that can feed on cyanobacteria, so in step (a), a zooplankton is domesticated into a algae-eating insect that can eat cyanobacteria. Wherein the zooplankton in the step (a) is daphnia magna (Daphnia magna) in the preferred embodiment of this method. The step (a) includes the following steps: (a1) using a specific formula to feed the domesticated Daphnia magna, improving the intestinal microbial composition of Daphn...

Abstract

The invention provides a method for repairing water ecology. The method comprises the following steps: (a), domesticating a zooplankton, and making the zooplankton ingest cyanobacteria pollution in an eutrophic water body to become an algae eating bug; and (b), putting the algae eating bug into the eutrophic water body which is polluted by cyanobacteria, wherein the algae eating bug ingests the cyanobacteria in the water body to purify the water body, repair underwater ecology balance, and form self purification of the water ecology.

Description

technical field [0001] The present invention relates to an ecological restoration method, in particular to an ecological restoration method for eutrophic water bodies. Algae-eating organisms are put into waters polluted by blue-green algae or green algae, and the blue-green algae in the water can be repaired. Algae polluted waters. Background technique [0002] The reason for the outbreak of blue-green algae is that various production activities of human beings discharge nitrogen and phosphorus nutrients into rivers, lakes and other water bodies. When the ecological self-purification ability of lakes is destroyed, nitrogen, phosphorus and other nutrients continue to accumulate in water bodies. The accumulation of a large number of single-celled algae, especially cyanobacteria (mainly Microcystis aeruginosa) floods and seriously pollutes the water quality. Most of the cyanobacteria cells have a well-developed alginate layer, and the outside of the cell is surrounded by a thi...
