Problems solved by technology

[0005] However, although the above-mentioned groundwater circulation equipment can effectively control the vertical flow direction of groundwater, since the well screens of the extraction pipe and the injection pipe are all fully open (that is, the screen opening angle is 360 degrees), it is still unable to effectively limit the concentration of groundwater pollutants. Therefore, the proportion of pollutants extracted by the extraction pipe is low, so the efficiency of on-site groundwater treatment is limited

Embodiment 1

[0064] Example 1 is to use as figure 1 The shown high-efficiency multi-angle well screen groundwater remediation equipment 100 equal-fold (100 times) scaled-down model is used to simulate the on-site treatment of groundwater, wherein the groundwater contains sodium bromide as a tracer substance, and its initial concentration is 3 weight%. According to the ratio of the sodium bromide concentration in the extracted groundwater to its initial concentration, the extraction ratio of groundwater pollutants can be known, and the specific screen opening angle, the number of injection well pipes and the evaluation results are listed in Table 2. I won't repeat them here.

Embodiment 2 to 3 and comparative example 1 to 2

[0066] Embodiments 2 to 3 and Comparative Examples 1 to 2 are carried out using the same high-efficiency multi-angle well screen groundwater treatment equipment 100 as in Embodiment 1, but Embodiments 2 to 3 and Comparative Examples 1 to 2 are performed by changing the injection well pipe. The sieve angle, its specific equipment parameters and evaluation results are listed in Table 2.

[0070] Proportion of groundwater pollutants

[0071] The proportion of groundwater pollutants referred to herein in the present invention refers to the proportion of the groundwater pollutants extracted by the well pipe, which is to add sodium bromide with an initial concentration of 3% by weight in the groundwater, and according to the extracted The ratio of bromide ion concentration contained in groundwater relative to its initial concentration is used to determine the proportion of groundwater pollutants extracted. The bromide ion co...

Abstract

A high efficiency groundwater remediation equipment with multi-angle well screens is provided. The equipment includes a movable water purifier, an extraction pipe and at least one filling pipe. A first wall of the extraction pipe has a plurality of first well screens, and each of the first well screens has a first screen angle of 90 DEG to 360 DEG. A second wall of the filling pipe has a plurality of second well screens. The first well screens and the second well screens are disposed face to face. Each of the second well screens has a second screen angle of 90 DEG to 270 DEG. The equipment has high mobility and can stabilize a flow direction of the ground water, restrict a location of pollutant of the groundwater, and increase percentage of the pollutant of the groundwater extracted by the extraction pipe to increase groundwater on-site remediation efficiency.

Description

technical field [0001] The present invention provides a groundwater improvement equipment, and in particular provides a high-efficiency multi-angle well screen groundwater improvement equipment with a specific opening angle. Background technique [0002] The qualitative change of groundwater caused by natural or man-made activities will affect the normal use or endanger human health and living environment. Pollutants produced by human activities, such as industrial and agricultural wastewater, industrial production, transportation or storage of chemical substances seep into the ground, may change the quality of groundwater and cause groundwater pollution. Especially in the stratum soil or groundwater around petrochemical factories, gas stations and other places, gasoline, diesel oil or organic solvents usually seep into it, which easily pollutes the soil and groundwater. [0003] The types of groundwater pollutants include inorganic substances, organic substances, microorga...
