①Removal of environmental pollution and black odor of organic compounds: Because the micro-nano bubbles have strong retention, they can produce more abundant CO2. Under the standard of colorful aerobic microbial strains, the environmental pollution index values of organic compounds are COD and BOD. Significant reduction, black odor condition subsided. In addition, harmful and harmful substances such as methane gas and hydrogen chloride caused by the dissolution of organic compounds at the bottom of the water quality are removed.

②Reduce the water content of nutrient salts in the water quality: Because the micro-nano bubbles have strong air flotation, retention and diffusivity, their lifting effect is weak, and the oxygenation of the water quality can reasonably inhibit the dissolution of soil organic matter of Pseudomonas aeruginosa at the bottom of the river. process, reducing the release of nitrogen and phosphorus nutrients underwater.

③Removal of algal blooms: Micro-nano bubble channel aeration has a strong re-oxygenation effect, which can improve the living conditions of aquatic organisms, thereby inhibiting the growth and development of algal plants.

④Improve water color and clarity. Various inorganic and organic chemical suspended solids, live phytoplankton and dead remains, large and medium-sized aquatic flower debris, dissolved organism debris, etc. in the water polluted by the environment are harmful to water color and The key chemical for clarity. Micro-nano bubble channel aeration can more reasonably promote the growth and development of aquatic microorganisms, thereby reducing soil organic matter in the water, significantly enhancing the clarity of water quality and improving water color.

⑤Reduce endogenous environmental pollution of sediment: After aeration and oxygenation of the micro-nano bubbles in the river channel, the surface oxygen content increases under the condition of the lake length, and the theme activities of aerobic microbial strains become stronger, and the sediment is promoted according to the whole process of metabolism of the microbial strains. The dissolution of organic chemical air pollutants gradually improves the underlying soil layer of inorganic materialization and blocks endogenous environmental pollution.
