Embodiment 1

[0062] This embodiment provides a river pollution source analysis and pollutant migration calculation method, including the following steps:

[0063] Step 1. Construct the watershed spatial attribute database and socio-economic information database. The watershed spatial attribute database includes watershed topography, distribution of main and tributary water systems, land use data, soil types, meteorological data, hydrological stations and their runoff and water quality monitoring data, etc. The socio-economic information database includes watershed administrative divisions, planting structures, etc. , the distribution of pollutant discharge points such as area, population, industrial living, and breeding in each administrative region, as well as the statistical data of point source pollutants and non-point source pollutants in different industries such as industry, living, breeding, and planting.

[0064] Step 2, according to the spatial information of the watershed water s...

Embodiment 2

[0074] Such as figure 2 As shown, a river pollution source analysis and pollutant migration calculation method provided in this embodiment includes:

[0075] Step 201: Based on the watershed spatial attribute database and socio-economic information database of the target watershed, determine the target sub-basin and establish the water quality monitoring section network of the main and tributary rivers of the target watershed; the watershed spatial attribute database includes the topography and geomorphology information of the watershed, the distribution information of the main and tributary rivers , land use data, soil type, meteorological data, hydrological station location information, and the runoff information and water quality information collected by the hydrological station; the socio-economic information database includes the administrative area of ​​the river basin, and the sewage discharge point corresponding to each administrative area of ​​the river basin Distrib...

Embodiment 3

[0091] Such as image 3 As shown, a river pollution source analysis and pollutant migration calculation system provided in this embodiment includes:

[0092] The target sub-basin and the water quality monitoring section network determination module 301 of the main and tributary rivers of the target watershed are used to determine the target sub-basin and establish the water quality monitoring section network of the main and tributary rivers of the target watershed based on the watershed spatial attribute database and the socio-economic information database of the target watershed; The spatial attribute database of the watershed includes topographic and geomorphic information of the watershed, distribution information of main and tributary water systems, land use data, soil type, meteorological data, hydrological station location information, and runoff information and water quality information collected by the hydrological station; the socioeconomic information The database in...

Abstract

The invention discloses a river pollution source analysis and pollutant transport calculation method and system, and the method comprises the steps: determining a target sub-basin based on a basin space attribute database and a social economic information database of a target basin, building a river main and branch water quality monitoring section network of the target basin, and determining a calculation unit; on the basis of a calculation unit and a social and economic information database, calculating the pollutant river entering quantity of each target sub-basin; based on a calculation unit and a drainage basin space attribute database, calculating the monthly average flow of the main and branch node sections; based on the pollutant river entering amount and the monthly average flow of the section of the main and branch flow nodes, considering the influence of karst development on the river leakage amount and the supply amount, and constructing a target drainage basin river water amount and water quality migration simulation model; the model is used for simulating the migration process of each pollutant in a target drainage basin, and scientific guidance is provided for drainage basin water environment treatment and implementation of water pollution control measures.

Description

technical field [0001] The invention relates to the technical field of river water environment treatment, in particular to a river pollution source analysis and pollutant migration calculation method and system. Background technique [0002] Against the background of more and more attention paid to the construction of ecological civilization, the investment in sewage treatment has increased significantly and technology has made significant progress. The amount of point source pollutants entering the river is getting smaller and smaller, while the proportion of non-point source pollution is gradually increasing. Reasonably determining the source of point source and non-point source pollutants in the river basin and their impact on the river water environment is of great significance for the improvement of the ecological environment and water pollution control. [0003] The pollution load calculation model is used to determine the sources of pollutants and their contributions,...
