Embodiment 1

[0033] The algae enrichment reactor is made of opaque materials, and the light source can only be illuminated from the top: a 40-mesh movable screen that fits the diameter of the container is embedded below the water surface, and it is cleaned regularly to prevent duckweed residues from falling The purpose of sinking is to affect the water quality and the purity of the collected algae. A transparent tube is connected to the bottom, and valves are arranged at both ends of the upper and bottom of the tube, and the collection and transfer of algae in the enrichment tube can be realized by adjusting the two valves.

Abstract

The invention relates to a method for enriching and transferring microalgae in an algae-polluted eutrophic water body by utilizing specific active organisms. The method comprises the following steps of: 1, introducing an algae-polluted natural water body into an enriching device, and inoculating duckweed in the enriching device to biologically inactive the algae; and 2, allowing biologically inactivated algae bacteria to be downwards enriched rapidly and finally reach a collection tube. The enriching device comprises a lift pump (1), a screen (2), an algae bacteria enrichment reactor (3), a valve 1 (4), the collection tube (5) and a valve 2 (6). The duckweed is inoculated in an amount which accounts for 10 to 100 percent of natural coverage rate. The invention aims to provide a novel high-efficiency method for enriching and collecting the algae in the algae-polluted eutrophic water body and overcomes the defects that the separation efficiency is low, the energy consumption is high, the treatment cost is high and secondary pollution is easily generated in the conventional enriching method; and the method has the advantages of finishing the enrichment and transfer of the algae by using the specific active organisms and having the function of water purification, along with the advantages of small investment, quick response, low energy consumption, high enrichment transfer rate, simplicity and practicability and no ecological pollution.

Description

technical field [0001] The invention relates to the technical field of biological environmental protection engineering, in particular to a method for enriching and transferring microalgae by using specific active organisms in algae polluted eutrophic water bodies. Background technique [0002] The increasing eutrophication of rivers and lakes has become a worldwide environmental problem. One of the consequences is the proliferation and even outbreak of algae, especially blue-green algae. At present, the water ecological environment pollution caused by the prevalence of algae has become a global problem. problem. Excessive algae will affect the landscape in the slightest, and cause serious alternative environmental pollution to the water body, resulting in a large reduction or even extinction of other biological populations in the water body, a serious ecological imbalance, and unusable water sources, such as cyanobacteria toxins and liver cancer-causing aeruginosa microcapsu...
