[0032] In order to facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0033] Working principle: To sum up, by means of the above technical solutions of the present invention, when the groundwater enters the treatment cylinder 401 through the conveying pipe 410, the second motor 403 and the first delivery pump 406 are started by the external controller. Then, the output shaft of the second motor 403 drives the rotating rod 404 to rotate. Then, the rotating rod 404 drives the mixing blades 405 to rotate. Then, the agent in the storage tank 407 is conveyed into the output pipe 408 through the first delivery pump 406, and then it is sprayed into the agitated groundwater through the nozzle 409, so that the groundwater can be mixed with the agent, so as to better ensure the osmotic reaction effect. Then, it is conveyed into the wall 1 through the input pipe 402. When the pretreated groundwater enters the wall, the five filter gratings 301 perform multiple filtration treatments on the incoming groundwater. After a long time of filtration and penetration treatment inside the wall 1, impurities adhere to the filter gratings 301, and the impurities will affect the osmotic reaction efficiency. The second delivery pump 306 and the first motor 302 are started by the external controller. Then, the output shaft of the first motor 302 drives the connecting seat 303 to rotate, and then drives the clamped threaded rod 304 to rotate, so that the cleaning scraper 305 connected to the threaded rod 304 moves from bottom to top, so as to clean the filter gratings 301, so as to avoid the osmotic reaction effect. The filter gratings 301 can be replaced by setting the sealing cover 2. Then, the second delivery pump 306 generates suction, and the collected impurities are conveyed into the collection box 308 through the cooperation of the collection cover 307 and the collection pipe 309;

[0034] After the filtration is completed, the first control valve 5 and the second control valve 6 are closed by an external controller. Then, the groundwater after the permeation reaction enters the treatment cover 413 through the treatment pipe 412. Next, the detection probe 414 is inserted into the detection cylinder 7. Then, a plurality of sealing rings 8 seal the detection probe 414. Then, the electric push rod 9 is started by the external controller. Next, the moving end of the electric push rod 9 drives the sealing plate 10 to move from one side, so as to detect the water quality in the treatment cover 413 (the detection probe 414 is set to be detachable in order to perform regular maintenance and detection on the detection probe 414, so as to better ensure the detection effect of the water quality). If it is unqualified, the second control valve 6 is opened by the external controller, and then the detected groundwater enters the circulation pipe 415, and then it is conveyed back into the wall 1 again for another permeation reaction. If the detection is qualified, the first control valve 5 is opened by the external controller to discharge it.
