Analysis method of ecological environment water demand in river course for algae bloom prevention and control

Abstract

The invention relates to a method for analyzing the water demand of the ecological environment in the river channel for the prevention and control of algae blooms, comprising the steps of: setting collection points, acquiring underwater terrain data, hydrological data, water conservancy engineering data, water quality data and water ecological data; constructing river channel hydrodynamics model; construct a water ecological numerical model; calculate the hydrological boundary conditions at the collection point; calibrate and verify the river hydrodynamic model and the water ecological numerical model; couple the calculation results of the river hydrodynamic model with the water ecological numerical model, and calculate the The ecological environment water demand in the river channel controlled by Huahua. The invention utilizes the self-purification ability of the water body, uses the hydraulic method to divert water and divert water, and prevents and controls the outbreak of algal blooms through reasonable scheduling of external projects, greatly reduces the workload and cost, and is easy to implement; dynamically adjusts the water flow according to the data collected in real time, The implementation cycle is greatly reduced, and the timeliness is high; it is conducive to the realization of regional environmental autonomy and the unified allocation of water resources.

Description

technical field [0001] The invention relates to the technical field of water ecology, in particular to a water demand analysis method for an ecological environment in a river channel used for the prevention and control of algae blooms. Background technique [0002] With the increase of the population in the basin and the rapid development of industrial and agricultural production, a large amount of industrial wastewater and domestic sewage in cities and towns are discharged into the lake, which leads to the increase of nutrient salt and organic matter in the lake, the acceleration of the eutrophication process of the lake, the increasing shortage of water resources, and the ecological environment. Water demand has been paid more and more attention by relevant experts and scholars. In recent years, river water quality control efforts have been gradually increased, and water pollution in my country has been partially improved, but cyanobacteria blooms have not been effectively...
