Example Embodiment
[0034] Example 1:
[0035] see figure 1 , an injection device suitable for in-situ chemical soil remediation, comprising an inner core 1 and a permeable layer 2 wrapped around the periphery of the inner core, wherein the inner core is made of high-density polyethylene (HDPE) as raw material, extruded The shape of the inner core is a long flat plate with a width of 10cm and a thickness of 0.8cm; the outer surface of the inner core is provided with axial grooves and / or ribs, and the grooves and / or protrusions The ribs are arranged longitudinally to form channels, and the cross-arranged ribs form supports to prevent the permeable layer material from being embedded in the channels due to the pressure of the external soil;
[0036] In the permeable layer, the material of the permeable layer is non-woven fabric, and the hair surface of the permeable layer is turned outward and back to the inner core, and the permeation direction is from the inside to the outside, so that the pharma...
Example Embodiment
[0037] Embodiment 2:
[0038] see figure 2 , a system for arranging the above-mentioned injection device, the system for arranging the above-mentioned injection device is a plug-in machine 3, including a chassis, a main frame, a vibrating hammer, a cannula, and a plug, the plug is arranged at the front end of the cannula, so The plug is a round head plug; the height of the main frame is 15-30 meters, the setting depth is 15-24 meters, and the top is equipped with a pulley head for the take-off and landing of the vibrating hammer; the chassis is a crawler chassis.
[0039] The method for in-situ chemical remediation of soil using the above-mentioned system for laying injection devices includes the following steps:
[0040] (1) After the plug-in machine is in place, use the vibrating hammer to align the jack to sink, and connect the injection device through the cannula to the plug at the front. After the intubation is lifted, the injection device is left in the soil, that is,...
Example Embodiment
[0044] Embodiment three:
[0045] A method for in situ chemical oxidation remediation of soil, such as image 3 shown, including the following steps:
[0046] (1) Site characterization: In order to better design and implement in-situ oxidation technology, it is necessary to fully understand and characterize the geological and hydrogeological characteristics of the restoration site and the spatial and temporal distribution characteristics of pollutants. It mainly includes the nature, concentration and spatial distribution of pollutants, the determination of chemical parameters such as the amount of pollutants (adsorbed, dissolved, and by-products), and soil properties at different depths (alkalinity, pH, Eh), composition, water permeability coefficient, Determination of geological parameters such as porosity and groundwater flow. Site characterization adopts a combination of on-site monitoring with sample collection and laboratory instrument analysis, which is a commonly used...
