[0001] The present invention relates to the technical field of pollution control, and in particular to a pollution control result evaluation method and system based on big data. Background Art

[0002] By integrating IoT sensor data, enterprise emission data, pipe network topology information, meteorological and hydrological data, and combining deep learning models with dynamic causal analysis, it is possible to quantitatively evaluate the effect of sewage treatment. This is already a relatively mature technical means, but existing technologies often rely on traditional water quality monitoring station data and lack technical solutions for the fusion of multi-dimensional data such as pipe network pressure, real-time enterprise emissions, and surface runoff. Moreover, the existing technology for pollution control often only stays at the stage of discharge from sewage treatment plants, but fails to continue to evaluate its subsequent diffusion. Under actual environmental conditions, different rainfall and runoff will indirectly affect the concentration changes of pollutants, and even meet the standards when discharged but exceed the standards in the river, resulting in unstable pollution control. In view of the shortcomings of the existing technology, the present invention provides a pollution control result evaluation method and system based on big data. Summary of the invention

The diffusion distance refers to the length of the river between each monitoring point and the outlet of the sewage treatment plant. The historical data set and diffusion distance of each monitoring point in different treatment cycles are obtained respectively.

[0009] Furthermore, the process of combining the first evaluation coefficient in the distribution map to obtain the influence of different environmental conditions on different pollutants and constructing a corresponding interference analysis model includes: According to a single historical data set of a single monitoring point and a first evaluation coefficient in a corresponding processing period, the influence degree Y of the single monitoring point on a single water quality parameter in the corresponding processing period is obtained;

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention obtains the removal rates of different pollutants when they are discharged from the sewage treatment plant and uses them as the first evaluation coefficient. In combination with the water quality parameters, environmental parameters and diffusion distances at different monitoring points in the downstream river, the influence of different environmental conditions on the diffusion of different pollutants can be obtained, and then the second evaluation coefficient can be obtained, which is conducive to continuing to monitor the pollution situation of the treated pollutants during the diffusion process, and solves the limitation that the evaluation of pollution control results in the past only stays at the time of discharge, and can more accurately evaluate the control results of different pollutants. By constructing an interference analysis model, we can directly obtain the interference of different environmental conditions on the concentrations of different pollutants. According to the subsequent changes in rainfall and runoff, we can judge in advance whether the concentrations of different pollutants will be too high, and adjust the sewage treatment process in advance to avoid this situation. This can more effectively ensure that the sewage treatment results are always up to standard. BRIEF DESCRIPTION OF THE DRAWINGS
