Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0032] Such as Figure 1-3 As shown, the present invention provides an in-situ remediation system for organically polluted groundwater. The remediation system for organically polluted groundwater consists of an ozone generation and mixing system 1 , an ozone injection well 2 and an ozone injector 3 .

[0033] The ozone generation and compounding system 1 is composed of a compressed air preparation device, an ozone prepar...

Abstract

The invention belongs to the technical field of underground water remediation, and particularly relates to an organic polluted underground water in-situ remediation system, which is composed of an ozone generation and mixing system, an ozone injection well and an ozone ejector. The ozone generation and mixing system is composed of a compressed air preparation device, an ozone preparation device and an ozone concentration adjusting device; the compressed air preparation device consists of an air compressor, a refrigeration dryer and a dry compressed air storage tank; after the air compressor compresses the air, the temperature of the air rises, and meanwhile moisture in the air is separated out in a supersaturated mode; the saturated compressed air is frozen, cooled and dewatered by the refrigeration dryer to become dry compressed air with the pressure of 0.6-0.8 MPa and the dew point lower than 20 DEG C, and the dry compressed air enters the compressed air storage tank to be stored; ozone is in contact with organic matters in underground water to generate oxidation reaction, so that the purpose of degrading the organic matters is achieved, and the technical effect of degrading the organic matters is achieved.

Description

technical field [0001] The invention relates to the technical field of groundwater restoration, in particular to an in-situ restoration system for organically polluted groundwater. Background technique [0002] With the economic transformation in various parts of our country, a large number of industrial sites, industrial raw material storage tanks, damaged pipelines, etc. have been relocated, leaving a large number of organic pollution sites. As a part of the polluted site, groundwater is buried hidden and complicated, and poses a huge hidden danger to the health of surrounding people and the environment. [0003] For organic pollution of groundwater, the main methods used in the treatment process include extraction-treatment, in-situ ventilation, circulation wells, biological remediation, electrochemical remediation, in-situ oxidation (or reduction) injection and other technologies. Among them, due to the advantages of high oxidation-reduction potential, strong oxidation,...
