Eutrophicated water body restoration design based on ecological system model and biological manipulation technology

Abstract

The invention provides a eutrophic water body restoration design based on an ecological system model and a biological manipulation technology, and relates to the technical field of eutrophic water. The eutrophication water body remediation design based on the ecological system model and the biological manipulation technology comprises the following steps: 1, carrying out water treatment; the method comprises the following steps: S1, collecting organisms in a damaged water body, and collecting debris, planktons, fishes and benthonic animals; s2, according to existing data, constructing an Ecopath model of a water ecological system, and comprehensively analyzing an energy flow process, a nutrition-level structure and overall characteristics of the ecological system of the system; s3, performing conversion through a built-in empirical formula of the Ecopath model to obtain actual measurement data of the plankton and the debris at the collection point; s4, checking the output result of the model, and calculating the primary production quantity of unutilized aquatic plants and floating algae; and S5, determining the fish putting amount according to the primary production amount of the unused aquatic plants and the floating algae in the step S4. Through the repair design, the cost is effectively reduced, and the repair effect is improved.

Description

technical field [0001] The invention relates to the technical field of eutrophic water, in particular to a restoration design for eutrophic water based on an ecosystem model and biological manipulation technology. Background technique [0002] Eutrophication of water body means that under the influence of human activities, a large amount of nutrients such as nitrogen and phosphorus required by organisms enter slow-flowing water bodies such as lakes, rivers, bays, etc., causing algae and other plankton to multiply rapidly, and the amount of dissolved oxygen in the water body decreases. , the water quality deteriorates, and fish and other organisms die in large numbers. Under natural conditions, lakes also transition from oligotrophic to eutrophic, but this natural process is very slow. However, the eutrophication caused by the artificial discharge of industrial wastewater and domestic sewage containing nutrients can appear in a short period of time. When eutrophication occu...
