Problems solved by technology

However, the above-mentioned reports all focus on a certain aspect or a certain biological species, and do not build a complete aquatic ecosystem from the structural composition of the ecosystem. The effect of water treatment is not ideal, and it is difficult to continue to exert the self-purification function of the ecosystem.

Abstract

The invention discloses a method for reconstructing an eutrophic water body ecosystem. The method comprises the steps of pretreatment, reconstruction, stocking of benthonic animals, stocking of filter-feeding fishes and the like, and is characterized in that the method for reconstructing the eutrophic water body ecosystem is defined from the aspects of substrate restoration of the eutrophic water body, configuration of biological species and the like. And later maintenance measures are provided. The method is simple to operate, easy to master, low in cost and good in treatment effect of the eutrophic water body, the nitrogen and phosphorus content of the water body can be reduced by 70% or above, and the method can be widely applied to ecological restoration and treatment of small and micro wetlands such as ponds, ditches, reservoirs and landscape water bodies.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a method for rebuilding an eutrophic water body ecosystem. Background technique [0002] With the advancement of urban construction in our country, a large amount of waste containing nitrogen and phosphorus and other organic pollutants are discharged into the water body. Since the amount discharged exceeds the self-purification capacity of the water body, eutrophication of the water body is induced, resulting in a large number of algae in the water body. Dissolved oxygen in the water body, resulting in the death of aquatic organisms, and the gradual extinction of the entire water ecosystem, and then evolved into a black and smelly water body. According to my country's relevant water resources survey report, among the 118 water bodies that are greatly disturbed by human beings, eutrophic water bodies account for 78.6%, and the pollution situation is beco...
