Construction method for water body self-cleaning ecological chain

Abstract

The present invention relates to a construction method for a water body self-cleaning ecological chain. The method comprises the following steps: feeding parent bacteria of common beneficial compound bacteria in water, wherein the feeding frequency is 1 time / month, and the feeding density of the parent bacteria of the common beneficial compound bacteria is 300 g / km(3); domesticating cladocera zooplankton, and enabling the cladocera zooplankton to eat cyanobacteria in a polluted water body; according to polluted indexes of the water body, feeding beneficial microorganisms in the water body, wherein the beneficial microorganisms can live together with the cladocera zooplankton; and planting submerged macrophytes on the water bottom, planting emergent macrophytes at shoreside of the water body, and planting floating macrophytes on the surface of the water body. The water body ecological restoration effects can ensure that water is crystal clear, main eutrophication indexes of water can reach a national surface water third-class water quality standard (a drinking water resource basic standard), and wherein data can be measured by a a water quality monitoring authority.

Description

technical field [0001] The invention relates to an ecological restoration method, in particular to a method for constructing a self-purification ecological chain of water bodies. Algae-eating organisms are put into waters polluted by cyanobacteria or green algae, and by devouring the blue-green algae in the waters, it can repair the water body polluted by cyanobacteria or green algae. 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...

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

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
