[0034] The lower end of material box 11 is fixed with taper nozzle 19 communicated with outlet 18, taper nozzle 19 is provided with baffle 20, baffle 20 blocks taper nozzle 19, the upper end of baffle 20 is fixed with connecting rod 21, and the upper end of connecting rod 21 is fixed with taper plug 12. Taper plug 12 is elastically slidably connected with the upper end of material box 11. Specifically, a plurality of light rods 13 are slidably arranged on taper plug 12, light rods 13 are vertically arranged and penetrate through taper plug 12, the upper end of light rods 13 is fixed on the upper end of material box 11, the lower end of light rods 13 is fixed with baffle 15, and lower spring 14 is sleeved on light rods 13 between baffle 15 and taper plug 12. The top plate of material box 11 above taper plug 12 is provided with opening 27.

[0035] The upper end of box 1 is elastically slidably provided with filling pipe 29. Specifically, the upper end of filling pipe 29 above box 1 is fixed with stop ring 23, and upper spring 24 is sleeved on filling pipe 29 between stop ring 23 and box 1.

[0036] The lower end of the filling pipe 29 is provided with a plurality of grooves 22 in the circumferential direction, and the lower end of the filling pipe 29 penetrates the opening 27, the grooves 22 are located in the tank 11, and the inner side of the lower end of the filling pipe 29 abuts against the conical surface of the cone plug 12, and a space is arranged between the cone plug 12 and the filling pipe 29 to allow the peroxysulfate to be discharged from the grooves 22 into the tank 11.

[0037] The upper end of the box body 1 is provided with a limiting assembly for limiting the filling pipe 29.

[0038] The limiting assembly comprises a limiting rod 25, the limiting rod 25 comprises a flat upper portion and a vertical lower portion, the vertical lower portion of the limiting rod 25 is rotationally connected to the upper end of the box body 1, and the flat upper portion of the limiting rod 25 blocks the upper end of the blocking ring 23.

[0039] A driving assembly is arranged in the box body 1 to drive the dosing assembly to reciprocate in the transverse direction of the box body 1. The driving assembly comprises an ear plate 10 fixed on the tank 11, a horizontal lead screw 7 rotationally arranged in the box body 1, and an upper motor 8 fixed outside the box body 1, the output shaft of the upper motor 8 is concentrically and fixedly connected with the lead screw 7, and the lead screw 7 is threadedly connected with the ear plate 10.

[0040] The sewage is added into the box body 1 through the inlet pipe 2, and then the upper motor 8 is started to drive the lead screw 7 to rotate, when the lead screw 7 rotates, the tank 11 moves to the left through the ear plate 10, and when the tank 11 contacts the blocking rod 9, the upper motor 8 is turned off. At this time, the filling pipe 29 is concentric with the opening 27, and the filling pipe 29 is pressed downward, the upper spring 24 is compressed, and the lower end of the filling pipe 29 penetrates the opening 27 and enters the tank 11. When the filling pipe 29 moves downward, the cone plug 12 is driven to move downward, and when the cone plug 12 moves downward, the lower spring 14 is compressed, and the cone plug 12 drives the blocking plate 20 to move downward through the connecting rod 21. When the blocking plate 20 blocks the cone nozzle 19, the filling pipe 29 cannot continue to move downward. Then the limiting rod 25 is rotated, the flat upper portion of the limiting rod 25 blocks the blocking ring 23 on the filling pipe 29, and at this time, the peroxysulfate can be added into the tank 11 through the filling pipe 29. The peroxysulfate in the filling pipe 29 is discharged into the tank 11 through the grooves 22.

[0041] After the peroxysulfate is added, the limiting rod 25 is rotated, the flat upper portion of the limiting rod 25 loses the blocking of the blocking ring 23, the filling pipe 29 is restored under the elastic force of the upper spring 24 and exits from the opening 27. At the same time, under the elastic force of the lower spring 14, the cone plug 12, the connecting rod 21 and the blocking plate 20 move upward, and when the blocking plate 20 moves upward, the cone nozzle 19 is opened. After the cone nozzle 19 is opened, the upper motor 8 is immediately started, the upper motor 8 drives the lead screw 7 to reciprocate, and then the tank 11 reciprocates in the transverse direction of the box body 1, and the peroxysulfate discharged from the cone nozzle 19 can be uniformly added into the sewage in the box body 1. When the tank 11 reciprocates in the box body 1, the vibrator 16 can be started to ensure that the peroxysulfate in the tank 11 can be smoothly discharged from the cone nozzle 19.

[0042] The material box 11 can reciprocate in the transverse direction within the box body 1, can make the persulfate be uniformly added into the sewage in the box body 1, and can improve the mixing rate of the sewage and the persulfate.

[0043] When the filling pipe 29 is inserted into the material box 11 and the persulfate is added into the material box 11, the blocking plate 20 can block the cone nozzle 19, prevent the persulfate in the box body 1 from being discharged through the cone nozzle 19 during the process of adding the persulfate into the material box 11, and further cause the amount of the persulfate added into the part of the box body 1 below the filling pipe 29 to be too much, so as to ensure the uniformity of adding the persulfate into the sewage in the box body 1.

[0044] After the persulfate is added into the sewage, the ultraviolet lamp 26 is started, the persulfate is activated under the action of the light emitted by the ultraviolet lamp 26, and then a chain reaction is triggered to generate oxygen-containing species such as persulfate radicals (SO4-•), hydroxyl radicals (•OH), superoxide radicals (•O2-), and singlet oxygen (102). The above-mentioned oxygen-containing species have extremely strong oxidation ability and can effectively degrade organic pollutants and toxic substances in the wastewater.

The stirring assembly comprises a lower motor 5 fixed at the lower end of the box body 1, and a stirring rod 4 rotatably arranged in the box body 1, and the output shaft of the lower motor 5 is fixedly connected with the stirring rod 4.

[0046] The auxiliary mixing assembly comprises an aeration pipe 28 fixed at the lower end in the box body 1, and the aeration pipe 28 is in communication with an aeration pump fixed outside the box body 1.

[0047] After the persulfate is added into the sewage in the box body 1, the lower motor 5 and the aeration pump can be started, and the lower motor 5 can drive the stirring rod 4 to rotate. The cooperation of the aeration pump and the aeration pipe 28 can aerate the sewage in the box body 1, and then the sewage and the persulfate can be uniformly mixed.
