Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes. A macrophyte is an aquatic plant that grows in or near water and is either emergent, submergent, or floating, and includes helophytes (a plant that grows in marsh, partly submerged in water, so that it regrows from buds below the water surface). In lakes and rivers macrophytes provide cover for fish and substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Aquatic plants are a way to clean the water going into other bodies of water. The plants slow down the flow of water and capture pollutants and other sediments, the plants will eventually absorb the pollutants and the excess sediment will settle down to the bottom of the body of water.

The invention discloses a water pollution treatment method which comprises the following steps: pretreating a polluted water body, and removing larger particle pollutants from the source; biological treatment, wherein organic pollutants and heavy metal pollutants are removed through the combined action of a biological composite microbial agent and an adsorbent; ecological restoration: through the configuration of aquatic plants and organisms, heavy metal pollution and the like are further removed, and the ecological environment is improved for a long time; underground water treatment: underground water pollution is prevented from entering the downstream through interception and adsorption of an underground water permeation wall, and a three-dimensional treatment effect is achieved; and circular treatment, wherein the treatment effect is further improved through a circular treatment method of reflux dilution. According to special geological and hydrological conditions of the karst region in Guizhou, efficient removal of heavy metal and agricultural non-point source pollutants is achieved through a multi-means synergistic effect, the method has the advantages of being high in adaptability, low in cost, environmentally friendly and the like, guidance is provided for water pollution treatment in similar regions, and the method has high practical application value.
