A comprehensive control system and method for in-service industrial site pollution

Abstract

The invention provides an in-service industrial site pollution comprehensive management and control system and method, and relates to the technical field of site pollution comprehensive management and control. The system includes barrier prevention and control layer, barrier wall, pollution interception ditch, water diversion gate type permeable reaction barrier and pollution control monitoring well group; the barrier prevention and control layer is set on the surface of the industrial pollution site, and the barrier wall is set on the groundwater of the industrial pollution site The upstream boundary, the pollution interception ditch is set at the downstream boundary of the potential pollution increment device area in the industrial polluted site, the water diversion gate type permeable reaction barrier is set at the downstream boundary of the groundwater in the industrial polluted site, and the monitoring wells are set in the entire industrial polluted site and Prevention and control facilities on both sides. The above-mentioned system can complete the prevention and control of the surface barrier of the industrial site in service, the upstream barrier of groundwater, the pollution island in the stagnant water area of ​​the site, the hydraulic interception ditch in the potential pollution area, and the systemic prevention and control engineering construction of the permeable reaction barrier downstream of the groundwater. Comprehensive management and control of soil and groundwater pollution provides guarantee.

Description

technical field [0001] The invention relates to the technical field of comprehensive management and control of site pollution, in particular to a system and method for comprehensive management and control of in-service industrial site pollution. Background technique [0002] The production raw materials, auxiliary materials, intermediate products and products of petrochemical, chemical, metallurgy, mining and other industries contain many toxic and harmful substances, which belong to heavy polluting industries, and have large investment, continuous production operation, flammable and explosive, high temperature and high pressure, equipment There are many facilities and a large area. During the production process of such production enterprises, due to the running, running, dripping, leaking and accidents of the equipment and facilities, the organic, inorganic and compound pollution of the soil and groundwater of the production site is caused. The pollutants are disturbed by t...

AI Technical Summary

Problems solved by technology

However, it is still very difficult to remediate local soil and groundwater pollution in production sites of heavily polluted industries such as petrochemical, chemical, metallurgy, and mining. Large and immobile, it is generally difficult to stop production or relocate in a short period of time, and the period of periodic shutdown inspection and maintenance is also short, making it difficult to carry out systematic and effective repair construction operations, and even in-situ repairs are difficult to achieve the goal of pollutant treatment; and petrochemical, chemical, and Due to the particularity of the production process in metallurgical and other sites, there are many underground pipelines, and the core device area has extremely high requirements for breaking ground, fire, explosion-proof, anti-corrosion, anti-oxidation, etc., and repair construction operations are generally not allowed

[0004] The existing control technology mainly adopts engineering barrier measures to forcibly isolate and seal existing pollutants, the project investment is large, there is a lack of prevention and control measures for potential pollution increments, the ability to intercept and remove pollution plumes is weak, and it is difficult to implement on-site at industrial sites in service Larger, if it is applied on a large scale, the groundwater level will change greatly, which will affect the foundation and hydrogeological stability
