Method for controlling cyanobacterial bloom by utilizing composite strain and trace element

Abstract

The invention relates to a method for controlling cyanobacterial bloom, which is mainly characterized by throwing composite biological strains, trace elements and filter-feeding fishes into a water body so as to rapidly construct a beneficial bacteria-algae cycling system of the water body, fundamentally lower the eutrophication degree of the water body and and achieve the goal of thoroughly controlling the cyanobacterial bloom. The invention is suitable for the ecological management of various eutrophy water bodies and has simple operation, low cost, rapid management and obvious effect.

Description

technical field

[0001] The invention relates to the field of biological and environmental ecological engineering, in particular to a method for controlling cyanobacteria blooms. technical background

[0002] Cyanobacteria bloom is a water pollution phenomenon caused by the excessive reproduction of cyanobacteria caused by excess nutrients such as nitrogen and phosphorus in the water body. Accompanied by the cyanobacteria bloom, there are also a series of phenomena such as serious deterioration of water quality, destruction of water ecosystem, and peculiar smell of water, which have a serious impact on the ecological environment. At present, the control methods of cyanobacteria bloom mainly include three categories: physical method, chemical method and biological (ecological) method. Due to its unique ecological and environmental advantages, biological methods are gradually becoming an important means of controlling cyanobacterial blooms. The current commonly used methods o...

Examples

Embodiment Construction

[0012] Implementation steps of the present invention are:

[0013] 1. Put microbial strains and trace elements into the water body. According to the water quality testing situation of the water body, measure and calculate the strains and trace element doses that should be put in, conduct regular water quality testing, and make timely adjustments based on the testing situation. The microbial strains put in are composite freeze-dried strains, and the trace elements put in are highly soluble organic complexes.

[0014] Compound microbial strains include lactic acid bacteria, Lactobacillus acidophilus, Lactobacillus plantarum, Bacillus subtilis, Streptococcus faecalis, Streptococcus faecium, Lactobacillus casei, Pediococcus lactis, Bifidobacterium, Bacillus natto, yeast, photosynthetic bacteria , Rhodopseudomonas palustris, and Bacillus licheniformis. After cultivating bacteria on a special medium for 1-3 days at a temperature of 0-70°C, add a freeze-drying protective agent, fre...
