Description

Technical Field

[0001] The utility model relates to the technical field of groundwater restoration, in particular to a multi-stage treatment device for groundwater restoration. Background Art

[0002] Groundwater remediation refers to the use of extraction, gas extraction, bioremediation, infiltration reaction wall and other technologies to restore contaminated groundwater to its original water quality. Groundwater resources are an important part of water resources. The implementation of groundwater pollution control and remediation work is of great significance to the sustainable utilization of groundwater resources.

[0003] The patent with announcement number CN221319482U discloses a multi-stage treatment device for groundwater remediation. The multi-stage treatment device for groundwater remediation realizes the monitoring of the water level above the activated carbon filter through the cooperation between the straight cylinder, the first support rod and the floating part. When the water is draining slowly, the user can know it at the first time, which solves the problem that the existing treatment method is single and the user cannot find out in time when the filter structure is blocked, which affects the continuous progress of groundwater treatment and reduces work efficiency. In addition, through the cooperation between the box, the block and the curved rod, the activated carbon filter can be quickly replaced, which is convenient for the user to clean impurities on the activated carbon filter.

[0004] However, since the activated carbon filter has a large resistance, the water flow rate is low when passing through the activated carbon filter, which may affect the overall efficiency. Utility Model Content

[0026] A connecting assembly is provided between the first purification mechanism and the second purification mechanism, and the connecting assembly includes a pump 401 bolted to the side wall of the first purification box 201, the water inlet of the pump 401 is connected to the outlet pipe 402, the outlet pipe 402 is located in the first purification box 201 and below the filter plate 205, the water outlet of the pump 401 is connected to the connecting pipe 403, the other end of the connecting pipe 403 is fixedly connected to the side wall of the second purification box 301, the connecting pipe 403 is connected to the area of ​​the second purification box 301 above the activated carbon adsorption layer 304, and the pump 401 is started to discharge the water flow in the first purification box 201 that has undergone primary purification into the second purification box 301.

[0027] An auxiliary mechanism is provided above the activated carbon adsorption layer 304, and the auxiliary mechanism includes a piston plate 501 slidably connected between the inner walls of the second purification box 301. The piston plate 501 divides the area above the activated carbon adsorption layer 304 into two chambers. The upper chamber 502 is located above the piston plate 501, and the lower chamber 503 is located below the piston plate 501. An air supply pipe 504 is fixedly connected to the piston plate 501, and a one-way valve is provided in the air supply pipe 504.

While treating the groundwater, the hydraulic cylinder 507 is controlled to make the top plate 506 drive the top rod 505 to drive the piston plate 501 to move up and down. When the piston plate 501 moves upward, the air supply pipe 504 opens Open, the gas in the upper chamber 502 enters the lower chamber 503 to ensure the air pressure balance in the lower chamber 503. During the downward movement of the piston plate 501, the air supply pipe 504 is closed, and the external gas will not enter the lower chamber 503. Therefore, the downward movement of the piston plate 501 will squeeze the gas in the lower chamber 503, increase the pressure in the lower chamber 503, and facilitate to increase the efficiency of water flow through the activated carbon adsorption layer 304. The external gas enters and exits the upper chamber 502 through the vent 508. When the filter plate 205 needs to be replaced, the first top cover 202 is removed from the first purification box 201.

After replacement, the first top cover 202 and the second top cover 302 are respectively fixed to the first purification box 201 and the second purification box 301.
