Embodiment 1

[0045] A pollution source online monitoring system, including:

[0046] The pollution source signal receiving module 1 is used to receive pollution source monitoring data of pollutant discharge enterprises;

[0047] The gaseous pollutant detection module 2 is used to detect gaseous pollutants in the external environment of the pollutant discharge enterprise;

[0048] Liquid pollutant detection module 3, used to detect liquid pollutants in the external environment of the pollutant discharge enterprise;

[0049] The solid pollutant detection module 4 is used to detect solid pollutants in the external environment of the pollutant discharge enterprise;

[0050] The external environmental pollutant analysis module 5 is respectively connected to the gaseous pollutant detection module 2, the liquid pollutant detection module 3, and the solid pollutant detection module 4 to analyze the external environmental pollutants;

[0051] The comparison and judgment module 6 is used to judge the authentic...

Embodiment 2

[0083] This embodiment is improved on the basis of Embodiment 1. In step A, use the calculated initial content of each individual pollutant in gaseous pollutants, liquid pollutants and solid pollutants and the actually measured content of each individual pollutant to calculate the diffusion rate of each individual pollutant. Then use the diffusion rate of each individual pollutant and the pollutant diffusion rate obtained in step A2 to fit their common approximation function as the corrected diffusion rate. For each individual pollutant in gaseous, liquid and solid pollutants The initial content of pollutants is calculated twice. Through the secondary fitting of the pollutant diffusion rate, the accuracy of the calculation of the pollutant diffusion rate can be improved.

Embodiment 3

[0085] This embodiment is improved on the basis of Embodiment 2. In step B33, when reconstructing the iterated data, if the reconstructed data has a negative value, replace the negative data as follows:

[0086]

[0087] among them, To reconstruct the objective function before correction, Is the modified reconstruction objective function, x is the data after iteration, and H is the nonlinear observation operator corresponding to x.

[0088] By replacing the invalid negative data in the reconstructed data, the utilization rate of the reconstructed data can be improved, thereby improving the calculation accuracy of the change trend of each individual pollutant.

Abstract

The invention discloses a pollution source online monitoring system, and the system comprises a pollution source signal receiving module, a gaseous pollutant detection module, a liquid pollutant detection module, a solid pollutant detection module, an external environment pollutant analysis module, a comparison and judgment module, and a calibration module. The external environment pollutant analysis module comprises a gas-liquid pollutant combined analysis module, a gas-solid pollutant combined analysis module and a solid-liquid pollutant combined analysis module. The system can iron out the defects in the prior art, achieves the active analysis and judgment of the monitoring data through a monitoring system and improves the monitoring authenticity and accuracy.

Description

Technical field [0001] The invention relates to the technical field of pollution online monitoring, in particular to a pollution source online monitoring system and an analysis method thereof. Background technique [0002] With the development of industry, the impact of industrial production on the environment has become more and more obvious. In order to protect the environment, my country has strict regulations on the discharge of industrial enterprises. In order to conduct timely supervision of pollutant-discharging enterprises, environmental protection departments in various places have successively established online monitoring systems linked with pollutant-discharging enterprises' information. However, the existing monitoring system only passively receives information and data, and cannot actively control the authenticity and accuracy of the monitoring data. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a pollut...
