specific Embodiment 1

[0034] Specific embodiment 1, see figure 1 , a combined groundwater-soil remediation device for the polluted area of ​​a gas station, comprising an extraction unit 1 for extracting groundwater from the polluted area, a water purification device 2 for purifying the extracted groundwater, and a water purifier for purifying The final groundwater is returned to the water injection unit 3 in the polluted area.

[0035] The extraction unit 1 includes a lift pump 10 and a riser pipe 11 , the outlet of the lift pump 10 is connected to the riser pipe 11 , and a protective net covering the inlet of the lift pump 10 is installed at the inlet of the lift pump 10 .

[0036] The water purification device 2 comprises a sequentially connected degreaser 21 and a filter 22, the degreaser 21 is higher than the filter 22, the outlet of the riser 11 is connected to the inlet of the degreaser 21, and the outlet of the degreaser 21 is connected to the filter. 22 inlets are connected, the inlet of d...

specific Embodiment 2

[0048] Specific embodiment 2, see figure 2, On the basis of the specific embodiment 1, the difference is that the filter 22 is an annular filter, and the annular filter is surrounded by the periphery of the degreaser 21 . The outer side of the degreaser 21 is provided with at least three circumferentially arranged outlets; the top of the annular filter 22 is provided with an inlet end which is consistent with the number of outlets of the degreaser 21 and is connected to the outlet. It is convenient to reduce the occupied space. A flocculator (not shown) can also be installed between the filter 22 and the water injection unit 3, the height of the flocculator is lower than the height of the filter 22, the inlet of the flocculator is higher than the outlet of the flocculator, and the inlet of the flocculator Electromagnetic valves are installed on the outlet and the outlet of the flocculator is connected to the inlet of the main pipeline; the inlet of the flocculator is connect...

Abstract

The invention provides an underground water and soil combined remediation device for a contaminated area of a gas station. The device comprises an extraction unit, a water purification device and a water injection unit. The extraction unit comprises a lift pump and a lift pipe. An outlet of the lift pump is connected with the lift pipe. A protective net covering an inlet of the lift pump is installed at the inlet of the lift pump. The water purification device comprises a degreaser and a filter, wherein the degreaser and the filter are connected in sequence. The degreaser is higher than the filter in position. An outlet of the lift pipe is connected with an inlet of the degreaser. An outlet of the degreaser is connected with an inlet of the filter. An outlet of the filter is connected withan inlet end of the water injection unit. The water injection unit comprises a horizontally arranged main pipeline, and at least two vertically arranged branch pipelines. The tops of the branch pipelines are in butt joint with the main pipeline and communicate with the main pipeline. Water seepage holes are formed in the side walls of the branch pipelines. Compared with a traditional undergroundwater and soil combined remediation device, the underground water and soil combined remediation device is simplified without a gas injection unit, and is more convenient to operate, and more convenient to install and fix.

Description

technical field [0001] The invention relates to the technical field of soil and groundwater remediation, in particular to a combined groundwater and soil remediation device. Background technique [0002] With the rapid development of social economy, the quality of groundwater is deteriorating, and its pollution has become a worldwide environmental problem of concern to the whole people. Soil and groundwater pollution is a major environmental problem facing the world. It not only seriously affects soil quality and land productivity, but also endangers food security, human health and even ecological security. [0003] Gas station pollution, as an "atypical" and widespread problem in soil and groundwater pollution, deserves more attention. Therefore, environmental remediation has become an important scientific and technological field that many countries and regions pay attention to, and regard it as an indispensable technical means to eliminate pollutants and restore soil ecol...
