[0029] Specifically, the ozone generator 803 transports the gas through the air inlet pipe 804 to the jet ring plate 801 until it is ejected from a group of nozzles 802. The ejected ozone can contact the slurry in the processing box 2, and can preliminarily decompose the phthalate in the slurry.

[0030] The second removal mechanism 9 includes: a material box 901 is arranged on the left side of the top end of the processing box 2, a Rhodococcus ruber material is placed inside the material box 901, a material pipe 902 is fixedly connected to the bottom end of the material box 901, one end of the material pipe 902 communicates with the inside of the processing box 2, and a control valve 903 is arranged on the material pipe 902.

[0031] Specifically, open the control valve 903, so that the Rhodococcus ruber material in the material box 901 is appropriately added into the inside of the processing box 2 through the material pipe 902. The added Rhodococcus ruber material contacts and degrades with the slurry in the processing box 2, and further removes the phthalate in the slurry.

[0032] The stirring mechanism 6 includes: on the right side of the top end of the base 1, a vertical plate 601 is fixedly connected. On the upper and lower sides of the left side wall of the vertical plate 601, connecting seats 602 are fixedly connected. On the right side of the adjacent end walls of the two connecting seats 602, first runners 603 are rotatably connected through bearings. On the left side of the adjacent end walls of the two connecting seats 602, second runners 604 are rotatably connected through bearings. A transmission connection is formed between the two first runners 603 and the two second runners 604 through two belts 605. A rotating column 606 is fixedly connected between the two first runners 603. In the middle of the outer part of the rotating column 606, a first gear 607 is fixedly connected. On the right side wall of the treatment tank 2, a motor 608 is fixedly installed. On the output end of the motor 608, a second gear 609 is fixedly connected. On the adjacent end walls of the two second runners 604, stirring columns 610 are fixedly connected. One end of each of the two stirring columns 610 penetrates into the interior of the treatment tank 2, and a group of stirring rods 611 are fixedly connected to the outer surface.

[0033] The first gear 607 and the second gear 609 are meshed and connected.

[0035] Specifically, start the motor 608 to drive the second gear 609 to drive the first gear 607 to rotate, the rotating column 606 rotates accordingly, the two first runners 603 rotate accordingly, through the transmission of the two belts 605, and then the two second runners 604 rotate, so that the two groups of stirring rods 611 rotate, and the mud in the treatment tank 2 is stirred, which can play an auxiliary role during decomposition and degradation.

[0036] The scraping mechanism 7 includes: a group of electric push rods 701 are fixedly connected to the top end inside the treatment tank 2. The telescopic ends of the group of electric push rods 701 are fixedly connected to the top end of the circular scraping plate 702.

[0037] The circular scraping plate 702 is in contact with the inside of the treatment tank 2.

[0038] Specifically, when the group of electric push rods 701 stretch and run, the circular scraping plate 702 scrapes on the inner surface of the treatment tank 2, which is convenient for cleaning the mud on its inner surface and mixing it with the mud in the treatment tank 2, facilitating the full removal of phthalates from the mud.

[0039] Working principle: Place the soil to be experimented into the treatment box 2, add an appropriate amount of water, start the motor 608 to drive the second gear 609 to drive the first gear 607 to rotate, and its rotating column 606 rotates accordingly. The two first runners 603 rotate accordingly. Through the transmission of the two belts 605, the two second runners 604 are driven to rotate, so that the two groups of stirring rods 611 rotate, and the soil in the treatment box 2 is stirred into a slurry state. Then start the ozone generator 803 to send the gas through the air inlet pipe 804 to the jet ring plate 801 until it is ejected from a group of nozzles 802. The ejected ozone can contact the slurry in the treatment box 2. With the rotation of the two groups of stirring rods 611, the phthalate in the slurry can be preliminarily decomposed. Then open the control valve 903, and appropriately add the Rhodococcus ruber material in the material box 901 into the interior of the treatment box 2 through the material pipe 902. The added Rhodococcus ruber material contacts and degrades with the slurry in the treatment box 2. With the rotation of the two groups of stirring rods 611, the phthalate in the slurry is further removed. During stirring, the stretching operation of a group of electric push rods 701 causes the circular scraper 702 to scrape on the inner surface of the treatment box 2, facilitating the cleaning of the slurry on its inner surface and mixing it with the slurry in the treatment box 2, so as to facilitate the slurry to fully remove phthalate. The removed slurry can be discharged from the discharge port 5.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
