Embodiment 1

[0042] The embodiment of the water environment pollution analysis system based on big data of the present invention is basically as attached figure 1 shown, including:

[0043] Acquisition unit, used to obtain basic river data and pollution source data;

[0044]The division unit is used to divide the river section according to the geographical information data of the river and the setting of the water environment quality monitoring section, divide the river into several control units with the monitoring section as the boundary, and the boundary of each control unit is the monitoring section;

[0045] The modeling unit is used to establish the pollutant traceability relationship of "monitoring section-pollution source" based on the river basic data, pollution source data and river section division, and establish the river pollution source and monitoring section water quality response relationship with the EFDC hydrodynamic model;

[0046] The analysis unit is used to analyze t...

Embodiment 2

[0064] The only difference from Example 1 is that

[0065] In S4, the discharge of pollutant sources in the river is also predicted based on the basic data of the river and the data of pollution sources, and the pollutants are allocated according to the concentrated location of the pollution sources and the river control unit. For example, construct a numerical model for the conservation of pollutant mass, solve its numerical solution through the water quality balance equation by using the finite difference method, and calculate the dynamic change of the discharge of pollutants on the monitoring sections of each river section with time; at the same time, when solving the numerical solution When , if the pollution sources are relatively concentrated and the river control unit is relatively large, then assign or set a higher initial pollutant concentration.

[0066] In addition, according to the discharge data of historical pollution sources of each monitoring section, the risk ...

Embodiment 3

[0069] The only difference from Embodiment 2 is that it also includes a collection device, such as the attached figure 2 As shown, the collection device includes: a first pole 1, a second pole 2, a rotating rod 3, a pin 4, a spring 5, a tension sensor 6, a controller 7, a water quality detector 8, a filter plate 9, and a housing 10 . The housing 10 is cylindrical, and the left and right ends of the housing 10 are equipped with filter plates 9, for example, by screws; the filter plates 9 are drilled with a plurality of filter holes. One end of the first strut 1 is welded on the inner wall of the housing 10, and the controller 7 and the water quality detector 8 are fixedly installed on the other end of the first strut 1, for example, by screws or by steel wires. One end of the second pole 2 is welded on the inner wall of the housing 10 , and the other end is hinged with the rotating rod 3 , that is, hinged through the pin 4 , and the rotating rod 3 can rotate freely around the...

Abstract

The invention relates to the technical field of water resource monitoring, in particular to a water environment pollution analysis system based on big data, comprising: an acquisition unit for acquiring river basic data and pollution source data; the division unit that is used for carrying out river reach division on the river; the modeling unit that is used for establishing a pollutant tracing relationship and a monitoring section water quality response relationship; the analysis unit that is used for performing pollution source structure analysis on each water outlet of each control unit according to the internal and external source contribution analysis and the pollution source type contribution analysis, and analyzing the contribution rate of the pollution source to the water quality of the monitoring section; and the output unit that is used for outputting an analysis result. According to the invention, the monitoring section is taken as the core, the pollution source causing themonitoring section can be analyzed, the pollution source with relatively large contribution degree to the river section water quality in the river is locked, and the technical problem that when an existing method is used for coping with sudden pollution sources, pollution source checking and tracing work cannot be effectively carried out in time is solved.

Description

technical field [0001] The invention relates to the technical field of water resources monitoring, in particular to a big data-based water environment pollution analysis system and method. Background technique [0002] With the continuous acceleration of industrialization and urbanization, environmental problems have become increasingly prominent, especially water pollution has become an important restrictive factor for the sustainable development of rivers. However, there are many sources of water pollution, and the workload of pollution traceability is heavy. It is difficult to carry out pollution source investigation and traceability in a timely and effective manner, which will affect the management and treatment of rivers. [0003] In this regard, Chinese patent CN109101781A discloses a calculation method for the contribution ratio of pollution sources in a complex river network, including steps: generalization of complex river networks; determination of the main stream ...
