Embodiment 1

[0031] A method for repairing polluted water bodies with immobilized composite microorganism technology. The microorganisms with remedial effects separated from the polluted water bodies to be repaired are mixed with functional strains and then immobilized, and then the immobilized composite microorganisms are put into the water to be repaired. Restoration is carried out in the repaired water body; functional strains include photosynthetic bacteria, yeast, Bacillus megaterium, lactic acid bacteria, and iron bacteria. parts, iron bacteria 10 parts.

[0032] In this example, the remedial microorganisms isolated from the polluted water body to be repaired include nitrifying bacteria, denitrifying bacteria and Bacillus subtilis, which are screened through the following steps: (1) Nitrifying bacteria, the enrichment screening method is : Take 1mL of polluted water samples into a Erlenmeyer flask containing 99mL of sterilized nitrifying bacteria enrichment medium, shake at a constan...

Embodiment 2

[0045] A method for repairing polluted water bodies with immobilized composite microorganism technology. The microorganisms with remedial effects separated from the polluted water bodies to be repaired are mixed with functional strains and then immobilized, and then the immobilized composite microorganisms are put into the water to be repaired. Restoration in the repaired water body; functional strains include photosynthetic bacteria, yeast, Bacillus megaterium, lactic acid bacteria, iron bacteria, the ratio of the functional strains is as follows: 20 parts of photosynthetic bacteria, 35 parts of yeast, 20 parts of Bacillus megaterium, 20 parts of lactic acid parts, iron bacteria 15 parts.

Abstract

The invention particularly relates to a method for repairing a polluted water body by using an immobilized composite microorganism technology. The method comprises: mixing microorganisms separated from a to-be-repaired polluted water body and having repairing function and functional strains, immobilizing, pouring the immobilized composite microorganisms into the to-be-repaired water body, and repairing, wherein the functional strains comprise: 10-40 parts of photosynthetic bacteria, 20-50 parts of yeast, 10-30 parts of Bacillus megaterium, 20-35 parts of lactic acid bacteria, and 10-20 parts of iron bacteria. According to the present invention, the functional strains separated and preserved by the company and in situ microorganisms in the corresponding polluted water source are compounded,and the polluted water body is repaired after the immobilizing, such that the repairing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of microorganism restoration of polluted water bodies, in particular to a method for repairing polluted water bodies by immobilized composite microorganism technology. Background technique [0002] With the acceleration of the industrialization process, the problem of water pollution is becoming more and more serious under the combined effect of human activities and climate environment. At present, the restoration methods for polluted water bodies are mainly physical methods, chemical methods, biological and ecological purification technologies. Physical and chemical methods to control water pollution generally involve a large amount of engineering and high cost. The biological and ecological purification technology of rivers mainly relies on the metabolic activities of microorganisms to degrade pollutants in water bodies, and is favored because of its cost-effectiveness. Immobilized microbial technology is...
