Description

Technical Field

[0001] The utility model relates to the technical field of restoration of polluted soil, and particularly relates to a mobile pumping and injection integrated device suitable for treating groundwater pollution in an industrial park in production. Background Art

[0002] An industrial park is an enterprise community formed by manufacturing enterprises and service enterprises on a fixed area, which improves the economic benefits of participating enterprises while minimizing their environmental impacts, and generally covers industries such as chemical industry, medicine, and metal manufacturing. More than 80% of the industrial parks in production have soil and water pollution due to leakage problems, showing characteristics such as multiple pollution types, wide pollution distribution, and combined pollution. Most industrial parks are built near water, especially the groundwater pollution is relatively serious, and there is a risk of pollution spreading downstream and to the surrounding areas. The pollution risk urgently needs to be repaired or controlled.

[0003] At present, the objects of the soil and groundwater remediation industry are mainly industrial lands that have been decommissioned and are waiting to be transferred. Since all production enterprises in the plot have stopped production and relocated, whether using ex-situ or in-situ treatment technologies to carry out treatment work, the plot has the implementation conditions. However, there are few studies and practices on the remediation and risk control of soil and groundwater pollution risks in industrial parks in production.

[0004] Compared with decommissioned sites, the biggest feature of industrial parks in production is that all enterprises are in production, with many buildings / structures and complex underground pipelines, limited operation space and conditions. And the leakage sources are often located in the production area, with a large number of production facilities distributed, small construction space, showing the characteristics of high pollution load and great pollution risk, which makes it difficult to effectively carry out the remediation and risk control work, especially in some small-space pollution areas where the pipeline system cannot be effectively laid out;

[0005] Secondly, the leakage points in current industrial parks in production are often relatively scattered and difficult to concentrate for treatment;

[0006] Finally, there may be some pollution leakage accidents during the production process of enterprises in production. To control the further spread of pollution, it is necessary to promptly carry out emergency disposal work to reduce the pollution load.

[0007] In the prior art, traditional equipment is mostly used to treat pollution sources, and these traditional equipment usually have poor mobility. Even integrated equipment generally needs to be transferred by a crane or the like, which is inconvenient to operate and difficult to cope with the emergency disposal of scattered and point-like leakage and the treatment of small spaces.

[0008] Another treatment method in the prior art is to configure a centralized equipment disposal area, which is connected to a common area through fixed injection and extraction flexible pipes to centrally repair and control the pollution in most areas. However, due to the narrow space or the inability to effectively install the corresponding pipes to the equipment disposal area inside the factory building, the cost cannot be controlled either. Therefore, the areas where centralized extraction and injection can be truly implemented are very limited. Summary of the Invention

[0009] The utility model solves the problems existing in the prior art and provides a mobile pumping and injection integrated device suitable for treating groundwater pollution in an industrial park under production. For some small-space pollution areas where the technology implementation is limited in the industrial park under production, the effective reduction of the groundwater pollution load can be achieved through pumping / injection treatment.

[0040] An extraction and injection unit for injecting the medicament prepared by the medicament preparation unit to a designated position or extracting pollutants from a designated position;

[0041] A directional regulation unit, arranged in cooperation with the extraction and injection unit, for performing anaerobic and aerobic aeration and regulating anaerobic and aerobic environments;

[0042] A driving unit for driving the overall movement of the device;

[0043] A control unit is provided in cooperation with the medicament preparation unit, extraction and injection unit, directional regulation unit, and driving unit.

[0044] In this utility model, the overall device is integrated through an integrated housing 1, restricted within a certain volume range, and can be flexibly moved to various small space areas. A driving unit is configured on the housing 1 to achieve the overall movement of the device.

[0045] In specific implementation, the driving unit can be set as an electric transportation mechanism, including moving wheels 3 provided under the housing 1 and a motor for driving the movement of the moving wheels 3, which is easily understood by those skilled in the art.

[0065] The control unit further includes a water quality sensor (not shown in the figure), and the water quality sensor is cooperatively arranged with the pumping and injection unit.
