Abstract

The invention discloses a method for restoring eutrophic water by utilizing rumex japonicas. The method comprises the following steps of: carrying N<+> ion injection treatment on rumex japonicas seeds; sowing the rumex japonicas seeds which are injected with the N<+> ions into the soil, transplanting the grown rumex japonicas plants to a planting floating floor; placing the planting floating floor on which the rumex japonica plants are cultivated into the eutrophic water; and purifying the water in a rumex japonicas growing process. Compared with the prior art, the method has the advantages that the plant rumex japonicas which can grow throughout the year and has a better water purifying effect is screened, and the N<+> ion injection technology is utilized to treat the rumex japonicas seeds; the water purifying effect of the obtained rumex japonicas variety on the eutrophic water under the low-temperature environment is greatly improved, and the obtained rumex japonicas variety is higher in application value.

Description

technical field

[0001] The invention relates to the technical field of environmental protection, in particular to a method for repairing eutrophic water body by using sheep's hooves. Background technique

[0002] Eutrophication refers to that under the influence of human activities, a large amount of nutrients such as nitrogen and phosphorus enter slow-flowing water bodies such as lakes and bays, causing rapid reproduction of algae and other plankton, a decrease in dissolved oxygen in the water body, and deterioration of water quality. A phenomenon in which fish and other living things die in large numbers. Under natural conditions, lakes will also transition from an oligotrophic state to a eutrophic state, but this natural process is very slow; while the eutrophication caused by the artificial discharge of industrial wastewater and domestic sewage containing nutrients can be achieved in a short period of time. appear within.

[0003] The prevention and control of eutrophi...
