Aquatic Plants Critical Element Determination

Aquatic plants are an important part of the water ecosystem. Aquatic plants mainly include aquatic vascular plants and higher algae, which are divided into four types, such as water-holding, floating, floating leaves, and submerged water.

The chemical composition and content of aquatic plants directly affect the intake of aquatic animal nutrition. The changes in population composition, population change, biomass, and community structure and function of aquatic organisms are important indicators to reflect the degree of eutrophication in the lake. Various biological indicators, especially chlorophyll amount, primary productivity, various indicator organisms, and biological indices are the key to evaluate and predict the eutrophication status of the lake.

Aquatic Plants Application Status

The treatment and remediation methods of polluted water bodies mainly include chemical, physical and biological methods, etc. The physical and chemical methods are more costly and less effective. The use of aquatic plants for sewage purification is a new ecological engineering technology, through the cultivation of aquatic plants, the use of aquatic plant roots and stems and leaves on the absorption of heavy metals, transformation, enrichment, and other functions can reduce the concentration of pollutants in the water body.

The purification process of aquatic plants for pollutants

• Degradation
• Adsorption
• Absorption
• Enrichment

In comparison, the biological method of ecological restoration using aquatic plants has the advantages of low treatment cost, low energy consumption, environmental protection, and aesthetic, no secondary pollution.
