What plants have a strong ability to clean up wastewater? 5

But now the water hyacinth in many places is crazy, the reproductive ability is too strong, and the manpower and material resources required to clean the water hyacinth are still higher than those of not planting water hyacinth.

By analyzing the absorption and decomposition of nutrients and pollutants such as nitrogen and phosphorus in water, different aquatic plants and their combinations can be selected to adapt to different polluted water bodies.

1. The enrichment of nitrogen and phosphorus by aquatic macroplants is one of the effective ways to control, regulate and inhibit lake eutrophication, and reduce pollution by absorbing nitrogen and phosphorus in the substrate through roots. The total nitrogen removal rate of submerged plants to the sea water body (including sediment) of Dianchi grass: the order of species removal ability was Elophylla, Bitter grass, Foxtail algae, Grate Eyelid, Ichrodis aureus, Vulgaris and Rotularella.

2. Algae, duckweed, stone lotus and other plants can enrich heavy metals in water in large quantities, but they will cause plant death and sedimentation along the food chain.

3. Lotus, reed, shallot, cattail grass and other water-holding plants can also play a role in purifying water quality, and also have an ornamental effect.

1. Water copy hoist.

Perennial perennial root floating herb. Because it has a large bubble like a gourd between the roots and leaves, it is also called water hyacinth. The stems and leaves hang over the water, and the tillers and branches creep on the water.

The flower color is gorgeous and beautiful. The leaves are emerald green and dark. It is a good plant with well-developed fibrous roots, fast tillering and propagation, extensive management, and purification of water quality.

2. Mangrove forests.

The ecological benefits of mangrove forests are its functions of preventing wind and waves, promoting siltation and beach protection, bank fixing and berm, and purifying seawater and air.

3. Reeds. aquatic plants, put in water. Its main functions can be summarized in several aspects: water purification, creating a living space for living organisms (birds, fish), I hope my answer can help you.

Plants that can purify water quality include water hyacinth, reed, duckweed, shallot, lotus, etc., water hyacinth is a good plant to monitor water pollution, reeds can absorb harmful substances in water, duckweed has obvious effect on purifying wastewater containing more pollutants, and shallots can remove phosphate and heavy metals in the water, and can purify water quality.

1. Water hyacinth

Water hyacinth, also known as phoenix eye blue, is a floating herbaceous plant, its flowers are light blue, is a common landscaping material in the garden waterscape, and the water hyacinth is suitable for growing in seriously polluted water, is a good plant to monitor environmental pollution, water hyacinth can also absorb a large number of heavy metal elements in the water during the growth process.

2. Reeds

The root system of the reed is very developed, suitable for growing in rivers, lakes and ponds, its stalks are tough, it is a good papermaking material, and the leaves, rhizomes and adventitious roots of the reed have aeration tissue, this tissue can help the reed absorb harmful substances in the water, so that the reed plays an important role in purifying sewage.

3. Duckweed

The surface of duckweed is emerald green, close to round, suitable for growing in warm areas, distributed in paddy fields, ponds and ponds, and duckweed has low requirements for the environment, it can also grow vigorously in seriously polluted water, duckweed will absorb a large number of harmful substances in the growth process, and the effect on purifying wastewater containing more pollutants is obvious.

4. Onions

Shallot is also known as cupola, pupa, water onion, etc., its root system is very developed, suitable for growing in the lake or shallow pond, is a more common cultivation of ornamental crops, shallots can grow in seriously polluted water, have a higher removal rate of phosphate in sewage, and can also purify mercury, cadmium, lead and other harmful substances in the water.

Duckweed. Duckweed is a water surface planktonic plant of the order Araceae, duckweed, and duckweed.

The phyllodes are symmetrical, the surface is greenish and colored, the back is light yellow or greenish-white or often purple, the whole margin, with 3 inconspicuous veins; 1 white filamentous root on the back; The phyllodes have a sac on the back, and the new phyllodes form a float in the sac, which is connected to the mother by a short stalk, and then falls off; 1 ovule in female flower; fruit nearly gyro-shaped; The seeds have a convex embryonic pararidge and longitudinal ribs.

Duckweed prefers warm climate and humid environment, avoid severe cold. Whole herbs can be used as feed for livestock and poultry. With the root of the whole herb into medicine, cold, pungent taste, function of diaphoresis rash, clear heat and water, the main treatment of surface fever, measles, edema and other symptoms.

Duckweed management methods.

1. Physical Methods:

When the biomass of duckweed is high, it is mainly limited by spatial factors, so after physical salvage, the growth space of duckweed can only be increased. That is, physical salvage will accelerate the growth and reproduction of duckweed, resulting in more and more by-seepage.

2. Chemical methods:

Commonly used chemical agents mainly include copper sulfate, permanganate, aluminum sulfate, ferrite composite agent, liquid chlorine, ozone and hydrogen peroxide. The use of chemical agents is undoubtedly an effective way to achieve remarkable results and quick results, but it is only a palliative method and must be used with caution.
