Intelligent restoration system and restoration method for polluted site

Abstract

The invention discloses an intelligent restoration system and restoration method for a polluted site, wherein the system comprises a real-time monitoring subsystem, a scheme decision subsystem and a restoration subsystem, the real-time monitoring subsystem is used for monitoring the information of the polluted site in real time and transmitting the information to the scheme decision subsystem, the scheme decision subsystem is used for judging the monitored information, making a decision, and selecting the corresponding repair subsystem for repair. According to the intelligent restoration system and method for the polluted site, the restoration strategy and the restoration target can be adjusted in time according to the current pollution situation change of the polluted site, the restoration efficiency is improved, the whole system is easy and convenient to operate and easy to maintain, and efficient restoration of the polluted site can be achieved.

Description

technical field [0001] The invention belongs to the technical field of soil (groundwater) restoration, and in particular relates to an intelligent restoration system and restoration method for polluted sites. Background technique [0002] Soil is the most important and basic comprehensive natural resource for human survival and development. Soil environmental conditions not only directly affect the development of the national economy and the safety of land resources and the environment, but also relate to the safety of agricultural products and human health. With the rapid development of my country's industrialization, unreasonable mining of mineral resources and its smelting discharge, landfill, chemical plant pollution, application of chemical fertilizers and pesticides and other reasons have caused serious groundwater and soil pollution, and the complex hydrogeology of the polluted site Due to the influence of conditions, the phenomenon of incomplete repair and secondary r...

AI Technical Summary

Problems solved by technology

[0004]However, due to the wide variety of pollutants in polluted sites, the physical and chemical properties are quite different, especially in some aged polluted sites, the occurrence forms of pollutants are more complicated, and the The complex hydrogeological conditions in the world have brought serious challenges to the actual efficiency of the restoration process, and the above-mentioned physical, chemical and biological restoration techniques cannot achieve good quality results

For example, the use of microwave heating technology to remediate contaminated soil, although it has a good removal effect on various organic pollutants, but because the soil cannot effectively absorb microwaves, microwave absorbing materials must be added to achieve this; chemical leaching technology is often not completely repaired, After rinsing, the soil still contains a lot of pollutants and pollutants wrapped in the eluent, and it is only suitable for small-scale and polluted soil remediation work; although the electrodynamic remediation technology is simple to operate, it takes a long time to process and is difficult to adapt Actual engineering needs

In addition, the current restoration of contaminated sites still has the problems of low automation and high safety risks.

[0005] In summary, the repair methods commonly used in the prior art have problems such as long treatment period, high treatment cost, and poor treatment effect. It is necessary to provide a short treatment period, An intelligent restoration system for polluted sites with low cost, significant treatment effect and flexible adjustment
