Description

Technical Field

[0001] The present invention belongs to the field of data communication of data centers, and in particular relates to a site multi-media pollution risk early warning and control system. Background Art

[0002] With the development of economy, various industrial parks are being built continuously, and the number of industrial enterprises is increasing. The pollution of groundwater is becoming more and more serious. When groundwater is polluted, it will in turn cause harm to industrial production and seriously threaten people's health. In the future, the field of environmental monitoring will shift from air and water to soil, and the importance of soil and groundwater testing will continue to increase.

[0003] Among the existing technologies, there are two main groundwater data collection technologies. One is manual rope monitoring, which takes a long time to monitor and is difficult to ensure the accuracy of monitoring. Especially in the new era when the amount of production and living sewage increases and the groundwater situation becomes increasingly complex, this technology is relatively backward. The other is that in some parks with relatively complete modernization, monitoring wells are built to monitor water quality, water quantity and groundwater pollution using sensors, but the monitoring indicators are very few and most of them cannot accurately reflect the groundwater pollution area.

[0004] Industrial parks usually involve a variety of industrial activities that may release hazardous substances, such as chemicals and waste. Predicting the health risks of certain types of groundwater pollutants can help detect potential risk issues at an early stage. The decline in groundwater quality may pose a risk to the health of workers in the park and the surrounding community; it can also help mitigate potential health issues for people.

[0005] Traditional calculation and prediction of health risk values ​​often use statistical data for trend analysis. Traditional early warning methods are unlikely to reflect the trends and impacts of groundwater human health risks in a timely manner. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a site multi-media pollution risk early warning and control system in view of the shortcomings of the background technology.

[0008] As a further preferred solution of the site multi-media pollution risk warning and control system of the present invention, in step 1, a database is established, specifically as follows: a database of physical and chemical toxicity parameters of pollution, a database of relevant environmental standards, a groundwater pollution monitoring database, and a geological / hydrogeological parameter database, which are stored in a list form and can be retrieved, imported / exported, read, searched, and queried by management personnel, and data storage parameters are established to build a BS data interface.

[0009] As a further preferred embodiment of a multi-media pollution risk early warning and control system for a site of the present invention, in step 2, monitoring data integration and statistical analysis are performed: a list of characteristic pollutants in the park groundwater is established, monitoring data of integrated pollutants are summarized according to the monitoring period, and information such as the monitoring frequency, monitoring date, location of monitoring wells, and affiliated enterprises of groundwater pollutants are displayed in a table; management personnel can edit and query the monitoring data, browse the changes in pollutant concentration over time or the concentration distribution at different monitoring points, perform statistical analysis on the data, and summarize the average value, maximum / minimum value, 95% confidence upper limit, and confidence lower limit of pollution in the park.

[0010] As a further preferred solution of the site multi-media pollution risk warning and control system of the present invention, in step 3, the pollution space is visualized as a picture: the data visualization management module based on GIS can display the relevant information of the park groundwater pollution on the large screen, and realize the spatial processing and visualization display of groundwater environment monitoring and evaluation, pollution concentration statistics, environmental prediction and warning, and source tracing analysis of groundwater data by means of geographic information technology and GPS positioning technology; specifically including: ① Display of the spatial distribution of each monitoring point, such as the name, location, affiliated enterprise, monitoring data, and compliance information of the groundwater monitoring point; ② Combine monitoring data with geographic information systems to realize the visualization of the spatial distribution of hydrogeological exposure conceptual models, pollutant concentrations, and groundwater flow field information on maps, spatial interpolation simulation, estimation of pollution exceeding standard range, and visualization of risk spatial distribution.

[0011] As a further preferred embodiment of a multi-media pollution risk warning and control system for a site of the present invention, in step 3, the intelligent management of the risk prevention and control of groundwater pollution in the park includes risk assessment and warning and pollution source tracing analysis; the risk assessment and warning specifically include: intuitively displaying a visualization conceptual model of groundwater exposure to human health and water environment in the park, displaying quantitative risk data of groundwater pollution based on water environment protection in the form of data tables, including risk value, hazard quotient and remediation target value, and estimating the pollution exceeding standard range using a spatial visualization module; establishing pollutant toxicity characterization and hazard identification, establishing a pollutant cross-media migration model under the inhalation vapor pathway, drawing a concentration attenuation prediction curve for the lateral migration of pollutants to groundwater, and determining future risk warning areas and warning levels based on the migration range; using a groundwater pollution lateral migration model based on water environment protection and a pollutant dose-effect exposure model to predict concentrations to calculate intervention values ​​and warning values ​​at the plant boundary location, and making a warning curve; during later monitoring, if it is found that the concentration of the pollutant is greater than the intervention value or warning value, an early warning signal is immediately issued.

[0012] As a further preferred embodiment of a multi-media pollution risk warning and control system for a site of the present invention, in step 3, the pollution source tracing analysis specifically includes: presenting the spatiotemporal distribution characteristics of groundwater pollution based on the monitoring results, and displaying the source of groundwater pollution through simulation calculation, combining with the characteristic pollution index database of enterprises in the park, and through model inversion calculation, using means such as pollution factor screening to quickly check the pollution sources and monitoring points in each enterprise, determine the source strength, location, and diffusion range of the groundwater pollution source, and use two-dimensional space simulation to display the tracing results, so as to provide a decision-making basis for pollution tracing, enterprise accountability, and accident emergency response.
