Box-type complete set soil and groundwater pollution two-phase extraction restoration device and application

Abstract

The invention relates to a box-type complete set soil and groundwater pollution two-phase extraction restoration device and an application. The box-type complete set soil and groundwater pollution two-phase extraction restoration device is integrated into a standard container and used for an organic pollution site. The box-type complete set soil and groundwater pollution two-phase extraction restoration device comprises an extraction and gas-liquid separation system, a tail gas humidity and temperature control system and a tail gas treatment system. Polluted underground water, pollutant-containing soil gas and a water insoluble free phase are extracted to the ground through an extraction well in a vacuum extraction mode, and then the separation of the gas, the water and the free phase is achieved through an inertia and gravity separation mode. The separated free phase is disposed in a recovered mode. The waste water is discharged after being subjected to ground facility treatment. The tail gas is exhausted through activated carbon adsorption treatment after humidity and temperature control. The box-type complete set soil and groundwater pollution two-phase extraction restoration device is convenient to transport and move and can be applied to a restoration project rapidly. The load of the tail gas treatment is significantly reduced and the efficiency of the activated carbon treatment is improved by installing the tail gas humidity and temperature control system. No fresh water is consumed in the operational process, and waste cold and heat of the system are fully used, so that the device is capable of saving energy and reducing emission.

Description

technical field [0001] The technology of the invention is a box-type complete set of soil and groundwater pollution two-phase extraction and repair device integrated in a container and applied to an organic matter polluted site and its application. Background technique [0002] With the continuous acceleration of urbanization in my country, more and more industrial enterprises have relocated, leaving behind a large number of polluted sites with environmental risks. However, there is a large demand for site reuse, and the scale of the site redevelopment market has expanded rapidly. If these contaminated sites are not repaired, the reuse of the site may have human health risks and even lead to serious consequences. In addition, due to industrial level, industrial technical conditions, extensive environmental management and environmental violations, a large number of existing industrial enterprises also have significant soil and groundwater pollution problems. For the above po...

Problems solved by technology

[0005] The technology of the invention solves the problem: it overcomes the shortcomings of the existing technology that it cannot be quickly transported and transferred, cannot be conveniently reused in different contaminated site restoration projects, and cannot effectively control the temperature and humidity of the extraction tail gas, and provides a box type that can be used industrially. A complete set of soil and groundwater pollution two-phase extraction and remediation device, the target pollutant types include volatile organic pollutants, biodegradable semi-volatile organic pollutants and recyclable non-water-soluble free phase
