Which aquatic plants can purify water pollution?

In addition to directly absorbing, fixing and decomposing pollutants, aquatic plants usually only indirectly participate in the decomposition of pollutants, and repair the environment by regulating microorganisms such as bacteria and fungi in the soil.

The plants with outstanding purification ability are Eichhornia crassipes, Alternanthera philoxeroides, Spirogyra, Oenanthe javanica, Acorus calamus, Lotus Roots, Typha Typha, Cynanchum komarovii, Aquatic Canna, Phalaenopsis, Alisma orientalis, Sagittarius, Iris lactuca and Allium tuberosum.

Eichhornia crassipes, Alternanthera philoxeroides and Polygonum cuspidatum are extremely fertile, so be careful not to cause ecological disasters.
