Description

Technical Field

[0001] The invention belongs to the technical field of electric connectors, and in particular provides a rotating reaction wall of replaceable reaction filler and a construction process thereof. Background Art

[0002] Permeable reactive wall remediation technology (PRB) has been widely used as an in-situ groundwater pollution treatment technology. Its working principle is to set up a permeable active substance reaction zone on the section where the pollutant suspension flows. When the pollutant comes into contact with the reaction zone, the pollutant is removed through adsorption, precipitation, chemical decomposition or biodegradation.

[0003] After a period of use, the surface of the medium of the traditional PRB technology will be clogged by pollutants, and the reaction medium will also show attenuation effect. Therefore, regular maintenance and replacement of the inner layer of the reaction body are required. Since the reaction wall is below the ground, the cost of maintenance and replacement of the reaction body is high. Summary of the invention

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a rotating reaction wall with replaceable reaction fillers, comprising a support frame, a circular sleeve, a filler chamber and a rotating shaft, the upper and lower halves of the inner cavity of the circular sleeve are the filler chambers, the rotating shaft is plugged into the center of the circular sleeve, and support frames are mounted on both ends of the rotating shaft;

[0005] The stuffing cabin is an open cavity, the stuffing cabin is filled with reactants, and a cabin door is movably installed at the stuffing cabin.

[0006] Furthermore, the hatch is a porous plate or a mesh structure.

[0007] Furthermore, the rotating shaft is drivingly connected to the motor.

[0008] The construction process of a rotating reaction wall with replaceable reaction filler is as follows:

[0009] Step 1: According to the flow direction of underground sewage, select the construction area on the surface and drill the construction trench in the area;

[0010] Step 2: Install two support frames in parallel on both sides of the construction trench;

[0011] Step 3: Place the circular sleeve into the construction groove and, at the same time, assemble the two ends of the rotating shaft with the two support frames;

[0012] Step 4: Rotate the annular outer sleeve to expose any filling chamber completely above the ground surface, open the chamber door and fill the reactant into the filling chamber;

[0013] Step 5: Control the annular outer sleeve to rotate 180 degrees, so that the stuffing chamber filled with the reactant rotates below the ground surface, until another stuffing chamber is completely exposed on the ground surface, and then repeat step 4;

[0014] Step 6: When the permeability of the reaction body decreases or loses its activity, repeat step 5, rotate a new reaction body below the surface, and replace the reaction body in the packing chamber that has been rotated up.

[0015] Furthermore, the digging direction of the construction trench is perpendicular to the flow direction of underground sewage, and the width of the construction trench matches the width of the circular sleeve.

[0016] The beneficial effects of using the present invention are:

[0017] This solution can maintain the activity and permeability of the reactants in underground sewage by replacing the reactants at any time, greatly improving the effect of groundwater treatment;

[0018] The failed reactor is rotated to the surface by rotating the annular sleeve and then replaced, which reduces the maintenance difficulty and cost of the reactor.

[0019] Through a short rotation, a new reactant can be placed into the underground contaminated area, avoiding the situation where a large amount of contaminated groundwater enters the downstream area due to the time required for post-processing of the reactant failure, thus failing to achieve the treatment effect.

[0024] The present invention is described in detail below with reference to the accompanying drawings.

[0025] Embodiment 1

[0026] Reference Figure 1-Figure 3 A rotary reaction wall with replaceable reaction packing includes a support frame 1, a circular sleeve 2, a packing chamber 3 and a rotating shaft 4. The upper and lower halves of the inner cavity of the circular sleeve 2 are the packing chamber 3. The rotating shaft 4 is plugged into the center of the circular sleeve 2, and the two ends of the rotating shaft 4 are provided with support frames 1.

[0027] The stuffing cabin 3 is an open cavity, the stuffing cabin 3 is filled with reactants, and a cabin door 301 is movably installed at the stuffing cabin 3 .

[0028] The hatch 301 is a porous plate or a mesh structure.

[0029] The rotating shaft 4 is drivingly connected to the motor.

[0030] Preferably, the reactant is a composite material comprising an adsorptive filter material and microorganisms.

[0031] Embodiment 2

[0032] The construction process of a rotating reaction wall with replaceable reaction filler is as follows:

[0033] Step 1: According to the flow direction of underground sewage 6, a construction area is selected on the surface 5, and a construction trench 7 is drilled in the area;

[0034] Specifically, the digging direction of the construction trench 7 is perpendicular to the flow direction of the underground sewage 6, the width of the construction trench 7 matches the width of the annular jacket 2, and the depth of the construction trench 7 extends to the underground sewage 6;

[0035] When the rock and soil layer around the excavation construction area is relatively stable, use a backhoe excavator (shallow trench within 5m) or a grab excavator (trench within 60m deep);

[0036] When the rock and soil layer around the excavation construction area is unstable or there is a risk of collapse in the excavation construction area, a caisson load-bearing cover is first used to protect the excavation construction area before excavation construction begins.

[0037] Step 2: Install two support frames 1 in parallel on both sides of the construction groove 7;

[0038] Step 3: insert the annular sleeve 2 into the construction groove 7, and at the same time, assemble the two ends of the rotating shaft 4 with the two support frames 1;

[0039] Step 4: rotate the annular outer sleeve 2 to expose any filling chamber 3 completely above the ground surface 5, open the chamber door 301 and fill the reactant into the filling chamber 3;

[0040] Step 5: Control the annular outer sleeve 2 to rotate 180 degrees, so that the filling chamber 3 filled with the reactant rotates below the ground surface 1, until another filling chamber 3 is completely exposed on the ground surface 5, and then repeat step 4;

[0041] At this time, the packing chamber 3 located below the ground surface 1 intersects with the underground sewage 6. The underground sewage 6 contacts the reactant during the process of flowing through the packing chamber 3 and is purified by the reactant.

[0042] Step 6: When the permeability of the reaction body decreases or loses its activity, repeat step 5, rotate a new reaction body below the ground surface 5, and replace the reaction body in the packing chamber 3 that has been rotated up.

[0043] Specifically, one or more monitoring wells are respectively set up upstream and downstream of the reaction wall to monitor the concentration of pollutants. By comparing the difference in pollutant concentrations upstream and downstream, it is determined whether the permeability of the reaction body is reduced or the activity is lost.

[0044] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present invention. As long as these changes do not deviate from the concept of the present invention, they all belong to the protection scope of the present invention.
